 What most people think of when they hear "markerless motion capture", is the system which uses vision-based deep learning to detect and identify anatomical landmarks (similar to - but not necessarily the same as - the physical markers in marker-based methods), in 2D image space (per camera, per frame). The 3D position of the subject is found through triangulation across multiple calibrated cameras. The output of these systems is therefore generally 4x4 pose matrices that fully represent the pose (3D position and orientation) of the associated [[visual3d:documentation:modeling:segments:segment_overview|segment]]. Examples of vision-based markerless systems include [[visual3d:documentation:third-party:theia|Theia]] and [[visual3d:documentation:third-party:fujitsu|Fujitsu]]. What most people think of when they hear "markerless motion capture", is the system which uses vision-based deep learning to detect and identify anatomical landmarks (similar to - but not necessarily the same as - the physical markers in marker-based methods), in 2D image space (per camera, per frame).
