General workflow • List of added markers as well as of scale-bars and information on their positions. • Structure of the project, i.e. number of chunks in the project and their content. 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. The software also allows to save PhotoScan Project file (*.psx) which stores the links to the processing results in *.psx file and the data itself in *.files structured archive. This format enables responsive loading of large data (dense point clouds, meshes, etc.), thus avoiding delays on reopening a hundreds-of-photos project. DEM and orthomosaic generation options are available only for projects saved in PSX format. 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. 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. Orthomosaics and digital elevation models (both DSM and DTM), as well as tiled models can be generated according to the user requirements. Point cloud and camera calibration data can be exported right after photo alignment is completed. All other export options are available after the corresponding processing step. If you are going to export the results (point cloud / mesh / tiled model / orthomosaics) for the model that is not referenced, please note that the resulting file will be oriented according to a default coordinate system (see axes in the bottom right corner of the Model view), i. e. the model can be shown differently from what you see in PhotoScan window. To align the model orientation with the default coordinate system use Rotate object button from the Toolbar. 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... command from the File menu. 2. Browse the destination folder, choose the file type, and print in the file name. Click Save button. 23
