Computes the features parameters in the camera frame (cP) thanks to the parameters given in the object frame (vpForwardProjection::oP) and the homogeneous matrix relative to the pose (cMo) between the object frame and the camera frame.
To set the parameters in the object frame you need to call setWorldCoordinates().
cMo | : The homogeneous matrix corresponding to the pose between the camera frame and the object frame. |
The features parameters in the camera frame (cP) are updated in the vpTracker::cP public attribute.
Implemented in vpSphere, vpPoint, vpLine, vpCylinder, and vpCircle.
