These functions are the following: saving the project; exporting reconstruction results you can only view a 3D model on the screen. On purchasing you will get the serial number to enter into the registration box on starting PhotoScan. Once the serial number is entered the registration box will not appear again and you will get full access to all functions of the program. Photographs can be taken by any standard digital camera, as long as you follow some specific capturing guidelines.

This section explains the general principles of taking and selecting pictures that provide the most appropriate data for 3D model generation. Basic rules Use a digital camera with reasonably high resolution 5 MPix or more. Wide angle lenses suit better for reconstructing spatial relations between objects than telephoto ones. Avoid not textured and flat objects or scenes. Avoid shiny and transparent objects. Avoid unwanted foregrounds and moving objects as much as possible.

Shoot shiny objects under a cloudy sky. Shoot pictures of the scene with a lot of overlap. Capture most important scene content from multiple viewpoints 3 or more. Do not crop or geometrically transform the images. More photos is better than not enough. Spending some time planning your shot might be very useful.

If you intend to set a reference coordinate system for reconstructed 3D model, make sure to identify or place on ground markers that will be used to set reference coordinate system and scale. Measure reference distance. Make sure to study the following schemes and read the list of restrictions before you get out for shooting photographs.

Capturing scenarios The following figures represent several typical capturing scenarios: 4. A short list of typical reasons for photographs unsuitability is given below. Modifications of photographs PhotoScan can process only unmodified photos as they were taken by a digital photo camera. Processing the photos which were manually cropped or geometrically warped is likely to fail or produce highly inaccurate results. Photometric modifications do not affect reconstruction results. In this case PhotoScan assumes that the 35mm focal length equivalent equals to 50 mm and tries to align the photos in accordance with this assumption.

If the correct focal length value differs significantly from 50 mm, the alignment can give incorrect results or even fail. In such cases it is required to specify initial camera calibration manually. The details of necessary EXIF tags and instructions for manual setting of the calibration parameters are given in the Camera calibration section Lens distortion The distortion of the lens being used to capture the photos should be well modeled using the Brown’s distortion model.

Otherwise it is almost impossible to build a precise 3D model. Fish eyes and ultrawide angle lenses are poorly modeled by the distortion model implemented, which leads to inaccurate reconstructions. If you are using PhotoScan in the full function not the Demo mode, intermediate results of the image processing can be saved at any stage in the form of project files and can be used later.

The concept of projects and project files is briefly explained in the Saving intermediate results section. The list above represents all the necessary steps involved in the construction of a textured 3D model from your photos. Some additional tools, which you may find to be useful, are described in the Chapter 4, Advanced use. Loading photos Before starting any operation it is necessary to point out what photos will be used as a source for 3D reconstruction. In fact, photographs themselves are not loaded into PhotoScan until they are needed.

So, when you “load photos” you only indicate photographs that will be used for further processing. To load a set of photos Select Add Photos In the Add Photos dialog box browse to the folder containing the images and select files to be processed. Then click Open button. Selected photos will appear on the Workspace pane. Photos in any other format will not be shown in the Add Photos dialog box. To work with such photos you will need to convert them in one of the supported formats. If you have loaded some unwanted photos, you can easily remove them at any moment.

To remove unwanted photos On the Workspace pane select the photos to be removed. Remove Items toolbar button. The selected photos will be removed from the Inspecting the loaded photos Loaded photos are displayed on the Workspace pane along with flags reflecting their status.

The following flags can appear next to the photo name: NC Not calibrated Notifies that the EXIF data available is not sufficient to estimate the camera focal length. In this case PhotoScan assumes that the corresponding photo was taken using 50mm lens 35mm film equivalent. If the actual focal length differs significantly from this value, manual calibration may be required.

More details on manual camera calibration can be found in the Camera calibration section. NA Not aligned Notifies that external camera orientation parameters were not estimated for the current photo yet. Images loaded to PhotoScan will not be aligned until you perform the next step – photos alignment. Aligning photos Once photos are loaded into PhotoScan, they need to be aligned. At this stage PhotoScan finds the camera position for each photo and builds a point cloud model.

To align a set of photos Select Align Photos In the Align Photos dialog box select the desired alignment options. Click OK button when done. The progress dialog box will appear displaying the current processing status. To cancel processing click Cancel button. Alignment having been completed, computed camera positions and a sparse point cloud will be displayed.

You can inspect alignment results and remove incorrectly positioned photos, if any. To see the matches between any two photos use View Matches The point cloud and estimated camera positions can be exported for processing with another software if needed. Incorrectly positioned photos can be realigned. To realign a subset of photos Reset alignment for incorrectly positioned photos using Reset Photo Alignment command from the photo context menu.

Set markers at least 4 per photo on these photos and indicate their projections on at least two photos from the already aligned subset. PhotoScan will consider these points to be true matches. For information on markers placement refer to the Setting coordinate system section. Select photos to be realigned and use Align Selected Photos command from the photo context menu. Alignment parameters The following parameters control the photo alignment procedure and can be modified in the Align Photos dialog box: Accuracy Higher accuracy setting helps to obtain more accurate camera position estimates.

Lower accuracy setting can be used to get the rough camera positions in a shorter period of time. Pair preselection The alignment process of large photo sets can take a long time. A significant portion of this time period is spent on matching of detected features across the photos. Image pair preselection option may speed up this process due to selection of a subset of image pairs to be matched. In the Generic preselection mode the overlapping pairs of photos are selected by matching photos using lower accuracy setting first.

In the Ground Control preselection mode the overlapping pairs of photos are selected basing on the measured camera locations if present. Constrain features by mask When this option is enabled, features detected in the masked image regions are discarded. For additional information on the usage of masks please refer to the Using masks section. Building model geometry 3D model reconstruction is a computationally intensive operation and can take a long time, depending on the quantity and resolution of loaded photos.

It is recommended to build a model with the lowest quality first to estimate the applicability of the chosen reconstruction method, and then to recompute the results using a higher quality setting. It is also recommended to save the project before building the geometry.

To build a 3D model Check the reconstruction volume bounding box. To adjust the bounding box use the Resize Region and Rotate Region toolbar buttons. Rotate the bounding box and then drag corners of the box to the desired positions. If the Height field reconstruction method is applied, the red side of the bounding box will define the reconstruction plane. In this case make sure that the bounding box is correctly oriented.

Select the Build Geometry In the Build Geometry dialog box select the desired reconstruction parameters. Reconstruction methods PhotoScan supports several reconstruction methods and settings, which help to produce optimal reconstructions for a given data set. It should be selected for closed objects, such as statues, buildings, etc. It doesn’t make any assumptions on the type of the object modeled, which comes at a cost of higher memory consumption.

Height field The Height field object type is optimized for modeling of planar surfaces, such as terrains or basreliefs. It should be selected for aerial photography processing as it requires lower amount of memory and allows for larger data sets processing. Geometry type Sharp Sharp geometry type option leads to more accurate reconstruction results and does not introduce extra geometry, like hole filling “patches”.

Manual hole filling is usually required at the post processing step. Smooth Smooth geometry type option produces watertight reconstructions with no or little holes on resulting surface. Large areas of extra geometry might be generated with this method, but they could be easily removed later using selection and cropping tools. Smooth setting is recommended for orthophoto generation. Reconstruction parameters Quality Specifies the desired reconstruction quality.

Higher quality settings can be used to obtain more detailed and accurate geometry, but require longer time for processing. Point Cloud quality setting is used for fast 3D model generation based solely on the sparse point cloud. The option is available for Smooth geometry type only.

Face count Specifies the maximum face count in the final mesh. Filter threshold Specifies the maximum face count of small connected components to be removed after surface reconstruction in percent of the total face count. The 0 value disables connected component filtering. Hole threshold Height field methods only Specifies the maximum size of holes to be filled after surface reconstruction in percent of the total surface area.

The 0 value disables automatic hole filling. PhotoScan tends to produce 3D models with excessive geometry resolution, so it is recommended to perform mesh decimation after geometry computation. More information on mesh decimation and other 3D model geometry editing tools is given in the Editing model geometry section.

Texture mapping modes The texture mapping mode determines how the object texture will be packed in the texture atlas. Proper texture mapping mode selection helps to obtain optimal texture packing and, consequently, better visual quality of the final model. Generic The default mode is the Generic mapping mode; it allows to parameterize texture atlas for arbitrary geometry.

No assumptions regarding the type of the scene to be processed are made; program tries to create as uniform texture as possible.

Adaptive orthophoto In the Adaptive orthophoto mapping mode the object surface is split into the flat part and vertical regions. The flat part of the surface is textured using the orthographic projection, while vertical regions are textured separately to maintain accurate texture representation in such regions.

When in the Adaptive orthophoto mapping mode, program tends to produce more compact texture representation for nearly planar scenes, while maintaining good texture quality for vertical surfaces, such as walls of the buildings. Orthophoto In the Orthophoto mapping mode the whole object surface is textured in the orthographic projection. The Orthophoto mapping mode produces even more compact texture representation than the Adaptive orthophoto mode at the expense of texture quality in vertical regions.

Single photo The Single photo mapping mode allows to generate texture from a single photo. The photo to be used for texturing can be selected from Texture from list. Keep uv The Keep uv mapping mode generates texture atlas using current texture parameterization.

It can be used to rebuild texture atlas using different resolution or to generate the atlas for the model parametrized in the external software. Texture generation parameters The following parameters control various aspects of texture atlas generation: Texture from Single photo mapping mode only Specifies the photo to be used for texturing.

Available only in the Single photo mapping mode. Blending mode not used in Single photo mode Selects the way how pixel values from different photos will be combined in the final texture. Average – uses the average value of all pixels from individual photos.

Mosaic – gives more quality for orthophoto and texture atlas than Average mode, since it does not mix image details of overlapping photos but uses more appropriate photo. Mosaic texture blending mode is especially useful for orthophoto generation based on approximate geometric model. Min Intensity – the photo which has minimum intensity of the corresponding pixel is selected.

Fill holes Enables hole filling for contiguous, orthophoto-like texture generation. Recommended for use only combined with Height-field geometry reconstruction mode. It is recommended to disable hole filling option when texturing stand-alone objects reconstructed in Arbitrary mode. Atlas width Specifies the width of the texture atlas in pixels. Atlas height Specifies the height of the texture atlas in pixels.

Saving intermediate results Certain stages of 3D model reconstruction can take a long time. The full chain of operations could easily last for hours when building a model from hundreds of photos.

It is not always possible to finish all the operations in one run. PhotoScan allows to save intermediate results in a project file.

PhotoScan project files may contain the following information: List of loaded photographs with reference paths to the image files. Photo alignment data such as information on camera positions, point cloud model and set of refined camera calibration parameters for each photo. Masks applied to the photos in project. Reconstructed 3D model with any changes made by user. This includes geometry and texture if they were built. List of added markers and information on their positions.

Structure of the project, i. You can save the project at the end of any processing stage and return to it later. To restart work simply load the corresponding file into PhotoScan. Project files can also serve as backup files or be used to save different versions of the same model. Project files use relative paths to reference original photos. Thus, when moving or copying the project file to another location do not forget to move or copy photographs with all the folder structure involved as well.

Otherwise, PhotoScan will fail to run any operation requiring source images, although the project file including the reconstructed model will be loaded up correctly. Exporting results PhotoScan supports export of processing results in various representations. Sparse and dense point clouds, camera calibration data, 3D models, orthophotos, and digital elevation models can be generated according to the user requirements.

All other export options are available after the geometry is built. In some cases editing model geometry in the external software may be required.

PhotoScan supports model export for editing in external software and then allows to import it back, as it is described in the Editing model geometry section of the manual. Browse the destination folder, choose the file type, and print in the file name. Click Save button. In the Export Points dialog box set the Point Cloud value for the Quality parameter if you need to export sparse point cloud.

To export a dense point cloud choose an approprite quality among the rest of the values. Specify the coordinate system and indicate export parameters applicable to the selected file type.

Click OK button to start export. In some cases it may be reasonable to edit sparse point cloud before exporting it. To read about point cloud edititing refer to the Editing sparse point cloud section of the manual. Camera calibration and positions data export To export camera calibration and positions data select Export Cameras Camera data export in Bundler file format would not save distortion coefficient k 3D model export To export 3D model Select Export Model In the Export Model dialog specify the coordinate system and indicate export parameters applicable to the selected file type.

If the model is referenced in local coordinates, PhotoScan can write a KML file for the exported model to be correctly located on Google maps. The texture file should be kept in the same directory as the main file describing the geometry. If the texture atlas was not built only the model geometry is exported. The most common application is aerial photographic survey processing, but it may be also useful when a detailed view of the object is required.

Orthophoto is often accompanied by the digital elevation model see the next section. In order to export orthophoto in the correct orientation it is necessary to set the coordinate system for the model first. Since PhotoScan uses original images to build an orthophoto, there is no need to build a texture atlas.

To export Orthophoto Select Export Orthophoto In the Export Orthophoto dialog box specify coordinate system to georeference the Orthophoto. Select Blending mode to be used for texture mapping.

For details please see the Building model texture section. Click Export button to start export. Write KML file option is available only if the model is georeferenced in WGS84 coordinate system due to the fact that Google Earth supports only this coordinate system.

World file specifies coordinates of the four angle vertices of the exporting orthophoto. This information is already included in GeoTIFF file, however, you could duplicate it for some reason. If you need to export orthophoto in JPEG or PNG file formats and would like to have georeferencing data this informations could be useful.

PhotoScan allows to export Orthophoto in different planar projections as well. You can select projection plane and orientation of the Orthophoto. PhotoScan provides an option to project the model to a plane determined by a set of markers if there are no 3 markers in a desired projection plane it can be specified with 2 vectors, i. Default value for pixel size in Export Orthophoto dialog refers to ground sampling resolution, thus, it is useless to set a smaller value: the number of pixels would increase, but the effective resolution would not.

PhotoScan allows for automatic hole filling. Check Fill Holes option in the Export Orthophoto dialog to generate holeless orthophoto. Split in blocks option in the Export Orthophoto dialog can be useful for exporting large projects. If you need an original file or, on the contrary, more compressed file, you should use external software to do the transformation. DEM export Digital elevation models DEMs represent the model surface as a regular grid of height values, and are often used for aerial photographic survey data.

Digital elevation model can be combined with orthophoto to produce a 3D model of the area. World file specifies coordinates of the four angle vertices of the exporting DEM.

This information is already included in GeoTIFF elevation data as well as in other supported file formatsfo DEM export, however, you could duplicate it for some reason. PhotoScan allows to export DEM in different planar projections in the same way as it is done for orthophoto export. See previous section. DEM parts corresponding to the areas visible on less than 2 source photos.

The values for the points of the grid that couldn’t be calculated will be set to the value indicated in no-data value box. To generate processing report Select Generate Report PhotoScan processing report represents the following data: Orthophoto and digital elevation model sketch. Camera parameters and survey scheme.

Image overlap statistics. Camera positioning error estimates. Ground control point error estimates. Processing report can be exported only after geometry is constructed and georeferenced. Advanced use Splitting project In some cases it is very hard or even impossible to generate 3D model of the whole object in one go. This could happen for instance if the total amount of photographs is too large to be processed. To overcome this PhotoScan offers the possibility of splitting the set of photos in several separate “chunks” within the project.

The alignment of photos, building geometry and forming the texture atlas may be performed on each chunk separately and then the resulting 3D models may be combined together. Working with chunks is no more difficult than using PhotoScan following the general workflow.

In fact, in PhotoScan always exists at least one active chunk and all the 3D model processing workflow operations are applied to this chunk. To work with several chunks you need to know how to create chunks and how to combine resulting 3D models from separate chunks into one model. Creating a chunk To create new chunk click on the Add Chunk toolbar button on the Workspace pane or select Add Chunk command from the Workspace context menu available by right-clicking on the root element in the Workspace pane.

After the chunk is created you may load photos in it, align them, generate mesh surface model, build texture atlas, export the models at any stage and so on. The models in the chunks are not linked with each other. To move photos from one chunk to another simply select them in the list of photos on the Workspace pane, and then drag and drop in the desirable chunk.

Working with chunks All operations within the chunk are carried out following the common workflow: loading photographs, aligning them, building geometry model, building texture atlas, exporting 3D model and so on. When a new chunk is created it is activated automatically. Save project operation saves the content of all chunks. To set another chunk as active Right-click on the chunk title on the Workspace pane. Select Set Active command from the context menu.

To remove chunk Right-click on the chunk title on the Workspace pane. Select Remove Items command from the context menu. Aligning chunks After the “partial” 3D models are built in several chunks they can be merged together.

Before merging the models they need to be aligned. In the Align Chunks dialog box select chunks to be aligned, indicate reference chunk with a doubleclick. Set desired alignment options. To cancel processing click the Cancel button. The following parameters control the chunks alignment procedure and can be modified in the Align Chunks dialog box: Method Defines the chunks alignment method.

Point based method alignes chunks by matching photos across the different chunks. Marker based method uses markers as common points between different chunks. The details on using markers are available in the Setting coordinate system section. Corresponding cameras should have the same label. Accuracy Point based alignment only Higher accuracy setting helps to obtain more accurate chunk alignment results.

Lower accuracy setting can be used to get the rough chunk alignment in the shorter time. Preselect image pairs Point based alignment only The alignment process of many chunks may take a long time. A signficant portion of this time is spent for matching of detected features across the photos.

Image pair preselection option can speed up this process by selection of a subset of image pairs to be matched. Constrain features by mask Point based alignment only When this option is enabled, features detected in the masked image regions are discarded.

For additional information on the usage of masks refer to the Using masks section. Chunk alignment can be performed only for chunks containing aligned photos. There is no need to perform chunk alignment for georeferenced chunks, as they are already in the same coordinate frame. Merging chunks After alignment is complete the separate models can be merged into a single model.

To merge models Select Merge Chunks command from the Workflow menu. In the Merge Chunks dialog box select chunks to be merged and the desired merging options. PhotoScan will merge the separate chunks into one. The merged chunk will be displayed in the project content list on Workspace pane. The following parameters control the chunks merging procedure and can be modified in the Merge Chunks dialog box: Merge markers Defines if markers from the selected chunks are merged only markers with the same labels would be merged.

Chunks merging result i. Batch processing PhotoScan allows to perform general workflow operations with multiple chunks automatically. It is useful when dealing with a large number of chunks to be processed.

Batch processing can be applied to all chunks in the Workspace, to unprocessed chunks only, or to the chunks selected by the user. Click Add to add the desired processing stages.

In the Add Job dialog select the kind of operation to be performed, the list of chunks it should be applied to, and desired processing parameters. Repeat the previos steps to add other processing steps as required. Arrange jobs by clicking Up and Down arrows by the right of the Batch Process Click OK button to start processing. Camera calibration While carrying out photos alignment PhotoScan estimates both internal and external camera orientation parameters, including nonlinear radial distortions.

For a successful estimation the information on approximate focal length values is required. Normally this data is extracted automatically from the EXIF In some cases, the 50mm guess can differ too much from the actual focal length. This can lead to the failure of the alignment process. In such cases it is required to specify the initial camera calibration manually.

To specify camera calibration manually Select Camera Calibration In the Camera Calibration dialog box, select Initial viewing mode. Select the photos to be calibrated. Modify the calibration parameters displayed in the corresponding edit boxes. Normally only fx, fy, cx and cy values should be corrected. Click Apply button to set the calibration. It should be selected for closed objects, such as statues, buildings, etc.

It doesn’t make any assumptions on the type of the object modeled, which comes at a cost of higher memory consumption. Height field surface type is optimized for modeling of planar surfaces, such as terrains or bas-reliefs. It should be selected for aerial photography processing as it requires lower amount of memory and allows for larger data sets processing. Source data Specifies the source for the mesh generation procedure. Sparse cloud can be used for fast 3D model generation based solely on the sparse point cloud.

Dense cloud setting will result in longer processing time but will generate high quality output based on the previously reconstructed dense point cloud.

Polygon count Specifies the maximum number of polygons in the final mesh. Suggested values High, Medium, Low are calculated based on the number of points in the previously generated dense point cloud: the They present optimal number of polygons for a mesh of a corresponding level of detail. It is still possible for a user to indicate the target number of polygons in the final mesh according to his choice.

It could be done through the Custom value of the Polygon count parameter. Please note that while too small number of polygons is likely to result in too rough mesh, too huge custom number over 10 million polygons is likely to cause model visualization problems in external software. Interpolation If interpolation mode is Disabled it leads to accurate reconstruction results since only areas corresponding to dense point cloud points are reconstructed.

Manual hole filling is usually required at the post processing step. With Enabled default interpolation mode PhotoScan will interpolate some surface areas within a circle of a certain radius around every dense cloud point.

As a result some holes can be automatically covered. Yet some holes can still be present on the model and are to be filled at the post processing step. Enabled default setting is recommended for orthophoto generation. In Extrapolated mode the program generates holeless model with extrapolated geometry. Large areas of extra geometry might be generated with this method, but they could be easily removed later using selection and cropping tools.

Point classes Specifies the classes of the dense point cloud to be used for mesh generation. Preliminary dense cloud classification should be performed for this option of mesh generation to be active. Note PhotoScan tends to produce 3D models with excessive geometry resolution, so it is recommended to perform mesh decimation after geometry computation. More information on mesh decimation and other 3D model geometry editing tools is given in the Editing model geometry section.

Building model texture To generate 3D model texture 1. Select Build Texture Select the desired texture generation parameters in the Build Texture dialog box. Texture mapping modes The texture mapping mode determines how the object texture will be packed in the texture atlas. Proper texture mapping mode selection helps to obtain optimal texture packing and, consequently, better visual quality of the final model. No assumptions regarding the type of the scene to be processed are made; program tries to create as uniform texture as possible.

Adaptive orthophoto In the Adaptive orthophoto mapping mode the object surface is split into the flat part and vertical regions.

The flat part of the surface is textured using the orthographic projection, while vertical regions are textured separately to maintain accurate texture representation in such regions. When in the Adaptive orthophoto mapping mode, program tends to produce more compact texture representation for nearly planar scenes, while maintaining good texture quality for vertical surfaces, such as walls of the buildings.

Orthophoto In the Orthophoto mapping mode the whole object surface is textured in the orthographic projection. The Orthophoto mapping mode produces even more compact texture representation than the Adaptive orthophoto mode at the expense of texture quality in vertical regions.

Spherical Spherical mapping mode is appropriate only to a certain class of objects that have a ball-like form. It allows for continuous texture atlas being exported for this type of objects, so that it is much easier to edit it later. When generating texture in Spherical mapping mode it is crucial to set the Bounding box properly. The whole model should be within the Bounding box.

The red side of the Bounding box should be under the model; it defines the axis of the spherical projection. The marks on the front side determine the 0 meridian.

Single photo The Single photo mapping mode allows to generate texture from a single photo. The photo to be used for texturing can be selected from ‘Texture from’ list.

Keep uv The Keep uv mapping mode generates texture atlas using current texture parametrization. It can be used to rebuild texture atlas using different resolution or to generate the atlas for the model parametrized in the external software.

Texture generation parameters The following parameters control various aspects of texture atlas generation: Texture from Single photo mapping mode only Specifies the photo to be used for texturing. Available only in the Single photo mapping mode. Blending mode not used in Single photo mode Selects the way how pixel values from different photos will be combined in the final texture. Mosaic – gives more quality for orthophoto and texture atlas than Average mode, since it does not mix image details of overlapping photos but uses most appropriate photo i.

Mosaic texture blending mode is especially useful for orthophoto generation based on approximate geometric model. Average – uses the average value of all pixels from individual photos. Max Intensity – the photo which has maximum intensity of the corresponding pixel is selected. Min Intensity – the photo which has minimum intensity of the corresponding pixel is selected. Exporting texture to several files allows to archive greater resolution of the final model texture, while export of high resolution texture to a single file can fail due to RAM limitations.

Enable color correction The feature is useful for processing of data sets with extreme brightness variation. However, please note that color correction process takes up quite a long time, so it is recommended to enable the setting only for the data sets that proved to present results of poor quality. To improve result texture quality it may be reasonable to exclude poorly focused images from processing at this step. PhotoScan suggests automatic image quality estimation feature.

PhotoScan estimates image quality as a relative sharpness of the photo with respect to other images in the data set. Saving intermediate results Certain stages of 3D model reconstruction can take a long time.

The full chain of operations could easily last for hours when building a model from hundreds of photos. It is not always possible to finish all the operations in one run.

PhotoScan allows to save intermediate results in a project file. PhotoScan project files may contain the following information: List of loaded photographs with reference paths to the image files. Photo alignment data such as information on camera positions, sparse point cloud model and set of refined camera calibration parameters for each calibration group.

Masks applied to the photos in project. Dense point cloud model with information on points classification.

Reconstructed 3D polygonal model with any changes made by user. This includes mesh and texture if it was built. List of added markers as well as of scale-bars and information on their positions. Structure of the project, i. You can save the project at the end of any processing stage and return to it later. To restart work simply load the corresponding file into PhotoScan. Project files can also serve as backup files or be used to save different versions of the same model.

Note that since PhotoScan tends to generate extra dense point clouds and highly detailed polygonal models, project saving procedure can take up quite a long time. You can decrease compression level to speed up the saving process.

However, please note that it will result in a larger project file. Compression level setting can be found on the Advanced tab of the Preferences dialog available from Tools menu. Project files use relative paths to reference original photos. Thus, when moving or copying the project file to another location do not forget to move or copy photographs with all the folder structure involved as well.

Otherwise, PhotoScan will fail to run any operation requiring source images, although the project file including the reconstructed model will be loaded up correctly. Alternatively, you can enable Store absolute image paths option on the Advanced tab of the Preferences dialog available from Tools menu.

Exporting results PhotoScan supports export of processing results in various representations: sparse and dense point clouds, camera calibration and camera orientation data, mesh, etc.

Point clouds and camera calibration data can be exported right after photo alignment is completed. All other export options are available after the 3D model is built. To align the model orientation with the default coordinate system use object button from the Toolbar.

Rotate In some cases editing model geometry in the external software may be required. PhotoScan supports model export for editing in external software and then allows to import it back, as it is described in the Editing model geometry section of the manual. Main export commands are available from the File menu and the rest from the Export submenu of the Tools menu. Point cloud export To export sparse or dense point cloud 1.

Select Export Points Browse the destination folder, choose the file type, and print in the file name. Click Save button. Specify the coordinate system and indicate export parameters applicable to the selected file type, including the dense cloud classes to be saved.

Click OK button to start export. Split in blocks option in the Export Points dialog can be useful for exporting large projects. It is available for referenced models only. You can indicate the size of the section in xy plane in meters for the point cloud to be divided into respective rectangular blocks. The total volume of the 3D scene is limited with the Bounding Box. The whole volume will be split in equal blocks starting from the point with minimum x and y values. Note that empty blocks will not be saved.

In some cases it may be reasonable to edit point cloud before exporting it. To read about point cloud editing refer to the Editing point cloud section of the manual. Tie points data export To export matching points 1. Select Export Matches In the Export Matches dialog box set export parameters.

Precision value sets the limit to the number of decimal digits in the tie points coordinates to be saved. Later on estimated camera data can be imported back to PhotoScan using Import Cameras command from the Tools menu to proceed with 3D model reconstruction procedure. Camera calibration and orientation data export To export camera calibration and camera orientation data select Export Cameras Camera data export in Bundler file format would not save distortion coefficients k3, k4.

PhotoScan is capable of panorama stitching for images taken from the same camera position – camera station. To indicate for the software that loaded images have been taken from one camera station one For information on camera group refer to Loading photos section.

To export panorama 1. Select Export – Export Panorama Select camera group which panorama should be previewed for. Choose panorama orientation in the file with the help of navigation buttons to the right of the preview window in the Export Panorama dialog. Set exporting parameters: select camera groups which panorama should be exported for and indicate export file name mask. Click OK button 6. Browse the destination folder and click Save button. Select Export Model In the Export Model dialog specify the coordinate system and indicate export parameters applicable to the selected file type.

If a model generated with PhotoScan is to be imported in a 3D editor program for inspection or further editing, it might be helpful to use Shift function while exporting the model. It allows to set the value to be subtracted from the respective coordinate value for every vertex in the mesh. Essentially, this means translation of the model coordinate system origin, which may be useful since some 3D editors, for example, truncate the coordinates values up to 8 or so digits, while in some projects they are decimals that make sense with respect to model positioning task.

So it can be recommended to subtract a value equal to the whole part of a certain coordinate value see Reference pane, Camera coordinates values before exporting the model, thus providing for a reasonable scale for the model to be processed in a 3D editor program.
