What's new


  • (3.3.17) New projection algorithm in the rayCloud to better detect outliers when marking the points.
  • (3.3.13) Micasense Atlas uploader connection
    • In the Index Calculator, a new button allows to efficiently upload the reflectance map to your Atlas account.

Other enhancements and changes

  • (3.3.19) The software starts 0.7 seconds faster in Windows.
  • (3.3.17) Up to 30% faster Geometrically Verified Matching in the standard calibration pipeline.
  • (3.3.17) Improved DTM algorithm. Better building detection parameters have been introduced.
  • (3.3.17) Information about the optimizer and lever-arm have been removed from the Quality Report.
  • (3.3.13) Improved color balancing algorithms. This reduces greatly purple artifacts on the edges of the orthmosaics.
  • (3.3.13) Improved Tetracam Rig support. In the rig page, the Tetracam rig is now created correctly with the right bands.
  • (3.3.7) LOD generation available in p4d files.
  • (3.3.4) Improved reading of Micasense Rededge camera.
  • (3.3.4) Improved calibration: correlation parameters are calculated faster and for all projects.
  • (3.3.4) The global mask is now also applied during orthomosaic computation.
  • (3.3.4) Updated coordinate system database, including Japanese Geodetic Datum 2011 and more.
  • (3.3.4) Slight improved calibration speed, mostly for larger projects.

Bug fixes

  • (3.3.19) Fixed reset button in the Mosaic Editor. 
  • (3.3.17) Fixed wrong pixel size determination for Aeryon images.
  • (3.3.17) Fixed Gamma (radiometric) corrections for the S110 NIR modified camera.
  • (3.3.14) Fixed wrong logo in Quality Report in Pix4Dmodel.
  • (3.3.13) Fixed crashes during DTM generation.
  • (3.3.13) Fixed updating of Image dots in MapView during step 2.
  • (3.3.13) Fixed parsing of geolocation file when the image name is a number.
  • (3.3.13) Fixed crash when uploading project with image in multiple directories.
  • (3.3.13) Fixed crash when creating a project out of multiple videos.
  • (3.3.13) Fixed issue in some values not being translated.
  • (3.3.13) Fixed issue when importing geolocation file with image filenames containing a + sign.
  • (3.3.7) The mosaic editor saves correctly its closing state when the user did not generate a DTM.
  • (3.3.7) Fixed missing icons in the quality report after merging.
  • (3.3.4) Fixed merging issue when the project or images are on remote drives.

Known issues

  • (3.3.4) Possible crash at the end of processing when disabling the automatic Quality Report display.
    • Workaround: don't uncheck the automatic Quality Report display
  • (3.3.4) In very rare cases, regression in calibration speed
    • Fixed in 3.3.7
