Abstract
Systems and methods for tracking using a tracking camera. For each frame of image data generated by the tracking camera, each blob of the frame is determined. For each determined blob, a 2D image coordinate of a centroid of the blob is determined in a coordinate space of the frame. A tracking system processor generates a first tag identifier from the determined 2D image coordinates. The tracking system processor uses the first tag identifier to access stored first tag information that is stored in association with the first tag identifier. The tracking system processor determines an absolute 3-space position and orientation of the tracking camera by performing a motion tracking process using the determined 2D image coordinates and the accessed first tag information.
