Topcon ContextCapture: 3D Point Cloud Generation

0 1
  • After completing 3D Mesh Reconstruction for a given photo block, 3D Point Cloud generation can be performed.
  • Select the General tab for a given Reconstruction.
  • Select Submit new production from the bottom right of the screen.
  • Enter a name for the production and select Next.
  • For the purpose of production, select the 3D Point Cloud radio button.
  • Select Next.
  • On the Format/Options screen, choose the format the 3D Point cloud will be created in:
    • Currently only *.LAS or *.POD formats are supported.
  • If necessary, to decimate the point cloud, enter the point sampling in either meters or pixels.
    • By default, Topcon Context capture will set the point sampling to every pixel which will correspond to the ground sampling distance (GSD) of the collected UAS data.
  • Once finished, select Next.
  • On the Spatial reference system screen, select the spatial reference system for the 3D Point Cloud from the pull down menu.
  • Once finished, select Next.
  • On the Extent screen, select the tiles that will be used for 3D point cloud generation. All tiles will be generated by default.
  • However, if necessary, the user can generate only the specific tiles needed rather than all tiles for a particular dataset to speed up processing time.
  • To select or deselect which tiles will be generated as a 3D point cloud, select the Select from 3D View button and choose on the 3D View which tiles to generate.
  • Once finished, select Next.
  • On the Destination screen, select Browse and navigate to the directory on the PC to save the 3D Point cloud tiles.
  • Once finished, select Submit to begin 3D point cloud generation.
