Using the rayCloud - PIX4Dmapper


The use of the rayCloud is optional and it can be used to:

  • Visualize the different elements of the reconstruction (Camera Positions, Reprojections (rays), GCPs, Manual / Automatic Tie Points, Processing Area, Clipping Box, Densified Point Cloud, Point Cloud Classification, 3D Textured Mesh, Video Animation Trajectories) and their properties.
  • Verify/ improve the accuracy of the reconstruction of the model.
  • Visualize point clouds created in other projects or with other software.
  • Georeference a project using GCPs and /or Scale and Orientation constraints.
  • Create Orthoplanes to obtain mosaics of any selected plane (for example, building facades).
  • Assign points of the point cloud to different point groups.
  • Improve the visual aspect.
  • Create objects and measure distances (polylines) and surfaces.
  • Create 3D fly-through animations (Video Animation Trajectories).
  • Export different elements (GCPs, Manual / Automatic Tie Points, Objects, Video Animation Trajectories).
  • Export point cloud files using points belonging to one or several groups.

    I am editing the densified point cloud. When I position and reshape the clipping box, then select the clip point cloud icon all I see is the extent of the clipping box on a fully black background - there is no clipped point cloud.

    Is there anything else I need to select or deselect

    Hi Malcolm,

    Our video academy on how to edit the 3D Point Cloud should help you. Please have a look ;-)

    Es posible hacer una superficie redonda? Es para saber el Área de una superficie redonda. En el caso de que no, como podria hacerla ? Gracias de antemano.

    Hola David, at the moment the surfaces can be defined with lines drawn in the rayCloud but not directly as a predefined shape (circle, square,...).

    In order to get an area of the circle, you could measure the radius/diameter of the area and calculate it manually.

    Is there any function/process available for point to point registration?

    Hello, could you please give us more information about what do you have in mind for "point to point registration"? Thank you :)
