What is new

  • Index Calculator
    The new Index calculator interface allows the user to create meaningful maps from any multi-spectral sensor and customize your NDVI as well as any vegetation index map directly in the software.
    For more information on how to use the Index Calculator: 47826703.

  • Point Cloud Filters
    Create filters based on image content to remove points from the 3D point cloud.
    • Point Cloud Densification Area: Define a 3D area that will be used for the point cloud densification. All points outside that area are removed.
      For more information on how to draw a Point Cloud Densification Area with the rayCloud Editor: 52385303.
      For more information on how to edit a Point Cloud Densification Area with the rayCloud Editor: 52394673.

  • Automatic improvement of the reconstruction
    The new Rematch and Optimize option allows the user to computes more matches between the images (and therefore more Automatic Tie Points) and reoptimizes the internal and external camera parameters. For more information: 48550678.

  • Generate the Quality Report independently
    Generate a new report once the reconstruction has been manually modified (e.g. adding GCPs). This allows the user to generate the report only once the reconstruction is adequate. For more information: 48550848.

  • Define the horizontal and vertical tolerance for GCPs
    For more information: 27896983.

  • Define the horizontal and vertical tolerance for the images position
    For more information: 28142498.

  • Generate a low resolution orthomosaic at step 1. Initial Processing
    For more information: 27133613.

  • New snapping option when drawing new objects 
    It is possible to use existing vertices for the new object being drawn by snapping to them.

  • Outputs
    • Choose the delimiter for XYZ output files. The delimiter can be set to spacetab, comma, or semicolon. For more information: 27345277.
