Bug fixes

  • Project management
    • Fix bug where project could not be opened when it was created with version 2.2 and the processing option Use MTPs under 1. Initial Processing > Matching > Matching Image Pairs > Custom were unselected.
  • Coordinates system
    • Fix bug where GCP and output coordinate system were not automatically updated when changing the image coordinate system from arbitrary to known coordinate system after the project has been created.
  • Camera models
    • Fix bug where no camera model from the user database could be selected.
  • Processing
    • Fix bug where the texture file was not generated when generating the 3D Textured Mesh in OBJ format. This happened when creating a new project and directly processing it.
    • Fix bug where the orthomosaic generated from a project with Sequoia's RGB images was fully transparent.
  • Index calculator
    • Fix bug where the degree symbol was not displayed correctly for thermal datasets.
  • Various UI bug fixes

 

Other changes

 

Known issues

  • Mac version
    • Software crashes or project is not loaded when either right clicking on the p4d file and selecting open with > Pix4Dmapper or when double clicking on the p4d file.
      Workaround: To open the project, start Pix4Dmapper and in the menu select Project > Open Project....
    • Cannot create nor process projects with images containing Airinov's calibration target. The software crashes.
      Workaround: no workaround exists for Mac.

 

Version 2.2.22

What is new

  • New Volumes view
    • The Volumes view allows you to easily measure volumes as well as to import and export them. For more information on how to use the Volumes view: 209268446.

 

  • Manually improve the 3D textured mesh
    • Use surfaces drawn in the rayCloud to improve the 3D textured mesh. This new tool helps to flatten surfaces or to fill holes on flat surfaces. For more information on how to improve the 3D textured mesh: 211083803.
Original 3D Textured Mesh Improved 3D textured Mesh: surfaces are flattened

 

Original 3D Textured Mesh Improved 3D textured Mesh: holes are filled

 

  • Automatic sky masking for Parrot Bebop images
    • New processing option that allows automatically masking the sky in Parrot Bebop images during step 1. When running step 2 Point Cloud Densification masked areas will not be used to reconstruct 3D Points. Therefore the sky will not be reconstructed at step 2. For more information: 205327965.
Densified point cloud without sky detection Densified point cloud with sky detection

 

  • Manually remove orthoplane background
    • Annotate images in the rayCloud in order to remove the background for orthoplane generation. For more information: 210226543.
Orthoplane with background Orthoplane with background removed

 

  • Optimized camera position uncertainties
    • The optimized camera position uncertainties are displayed in the quality report. The absolute position uncertainty is displayed in Figure 3 and the relative position uncertainty is displayed in Figure 5. For more information about the absolute and relative position uncertainty: 202558679.
Absolute camera position uncertainties Relative camera position uncertainties

 

  • 360° cameras processing
    • A new spherical model has been introduced, which allows processing of images and videos acquired with a 360° camera. Only equirectangular images and videos are supported. For more information on how to process images from a spherical camera: 210663886.

 

  • Automatic detection of the Airinov calibration targets
    • When an image with an Airinov calibration target is imported at project creation the target is automatically detected and the target region and albedo values are automatically extracted. For more information on how to use these targets with Sequoia: 206494883.
  • Pix4Dtagger
    • Pix4Dtagger is a distinct piece of software that automatically detects specific tags in images and marks them. This is useful to automatically mark GCPs/MTPs for a project. It generates a p4d file that can be opened in Pix4Dmapper. The executable is installed together with Pix4Dmapper. Note: Camera rigs are not supported (e.g. Sequoia, Airinov multiSPEC 4C, etc...)
      For more information on how to use Pix4Dtagger: 210729106.
  • French version
    • Pix4Dmapper is now available in French. For more information on how to set the language: 202557889.

 

Improvements

  • Processing options
    • 3D textured mesh: remove zipped OBJ option as it is no longer compatible with Sketchfab. By default the 3D textured mesh is generated in OBJ and FBX format.
  • Processing
    • Faster processing for multi-spectral rigs (e.g. Sequoia, etc...).
    • Easier and faster processing for images acquired by senseFly's albris.
    • Automatically remove foreground objects when generating the 3D Textured Mesh.
  • Outputs
    • The 3D Textured Mesh can be exported directly from the rayCloud layers by right clicking on a mesh layer. For more information: 202558079.
    • Save the DSM and orthomosaic generated with the SGM add-on.
  • Image annotation
    • Annotate images globally to remove objects that are visible in each image at the same location. E.g. Remove the feet of the drone. For more information: 210749586.
  • send to eMotion
    • The two options Send Map to eMotion and Send DSM to eMotion can now also be used when only step 1 is done or when only step 1 and step 3 are done. For more information: 207963566.
  • Quality report
    • Display all the processing options used for processing.
  • CLI
    • Pix4Dmapper outputs are now split between stdout (Info, UI, Processing) and stderr (Error, Warning) when using the command line. For more information: 202560329.

 

Other changes

  • Processing options
    • Discontinue the orthomosaic in Mapbox tiles format.
  • Quality Report
    • Figure 7. Georeference Verification will not be shown in the quality report anymore. The Ground Control Table can be used to assess the accuracy of the GCPs. The rayCloud gives a better indication about the GCP marks and reprojection.

 

Known issues

  • Software usage
    • Pix4Dmapper does not start on laptops with Windows 7 or 8 and with Nvidia Optimus Technology (Intel + Nvidia graphics cards). The system gets unstable (screen blinks, becomes black, blue screen, windows shows the login window, etc.). This happens when updating the Nvidia graphics drivers using the Nvidia GeForce Experience Tool, or when downloading and installing the latest drivers from the Nvidia web site.
      Workaround:
      a) Uninstall the latest Nvidia graphics drivers and reboot the computer. The Windows Update tool will then automatically install older drivers for which this issue was not happening.
      b) Update to Windows 10.
      For more information: 213090783.
  • Project management
    • Project cannot be opened when it has been created with version 2.2 and the processing option Use MTPs under 1. Initial Processing > Matching > Matching Image Pairs > Custom has been unselected.
      Workaround:
      1. Open the .p4d file in a text editor (e.g. Notepad++).
      2. Search for the line with <matchMtpMaxImagePair>0</matchMtpMaxImagePair> and replace 0 by 1.
      3. Save the .p4d file and close the text editor.
      4. Open the .p4d file in Pix4Dmapper.
      5. Go to the processing options.
      6. Under 1. Initial Processing > Matching > Matching Image Pairs > Custom unselect Use MTPs.
  • Coordinates system
    • GCP and output coordinate system are not automatically updated when changing the image coordinate system from arbitrary to known coordinate system after the project has been created.
      Workaround: select manually the image, GCP and output coordinate system.
  • Processing
    • Point cloud densification for full fisheye cameras is slower compared to version 2.1.
    • Software crashes when generating the 3D Textured Mesh for non RGB images and using the option Color Balancing for Texture.
    • Orthomosaic generated from a project with Sequoia's RGB images is fully transparent.
  • rayCloud
    • The rayCloud does not display properly when using a 4K screen.
