Template:Tracking Algorithm

Tracking Algorithm[edit]

Tracking Algorithm determines the way rigid bodies are tracked.
  • Auto-Select: Depending on the system camera count, Motive determines whether to use the marker-based tracking or the the ray-based tracking. For systems with fewer than 5 cameras, or the Duo/Trio Tracking Bars, ray based tracking is used. For systems with higher camera counts, marker based tracking is used.
  • Marker Based: Standard marker based tracking. It uses 3D coordinates obtained by the Point Cloud reconstruction to solve position and orientation of the rigid body.
  • Ray Based: In addition to the standard marker tracking, ray based tracking also utilizes untracked rays and rigid body definitions to solve for the position and orientation of the rigid body. In other words, when a marker is occluded because it did not satisfy the minimum required number of the tracked rays, this tracking algorithm can utilize the remaining untracked rays and the corresponding rigid body asset definition to provide more stable tracking of the rigid body. In order to utilize the Ray Based tracking, the Use Smart Markers setting must be enabled under reconstruction settings. Ray-based tracking is NOT supported for active markers
