In this section, you will find different blocks associated with the tracking module.
See section Graph Editor for more general introduction about graphs.

As usual, in order to add a block, you need to drag&drop the object into the graph editor.
Graph blocks are available for Groups, Cameras, and Objects.

Tracking group

Drag from: Tracking main tab

Block parameters:

  • data: a string containing the reconstruction data in camera frame (ids of markers and 3D positions), can be interfaced with blocks Listing, Dot selector, Position Spy, Transform 3d.
  • dataRemap: a string containing the reconstruction data in world frame (ids of markers and 3D positions), can be interfaced with blocks Listing, Dot selector, Position Spy, Transform 3d. This output is available only if the ground transformation was calibrated and Enable ground transform is on, empty otherwise.

Tracking camera

Drag from: Tracking main tab

  • data: a string containing the tracking data in camera frame (ids of markers and 2D positions in pixels), can be interfaced with blocks Listing.
  • 2dPointsRemaped: a string containing marker location data in the frame defined in the corresponding Editor (ids of markers and 3D positions).

Tracking object

Drag from: Tracking group editor / objects

Block parameters:

  • px: x-axis position in meters
  • py: y-axis position in meters
  • pz: z-axis position in meters
  • rx: x-axis rotation in degrees
  • ry: y-axis rotation in degrees
  • rz: z-axis rotation in degrees
  • vaild (true,false): defines whether the transformation is valid or not
