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.

Claim (Index 19):
The system of  claim 17 ,\n wherein the instructions that control the tracking system to generate the first tag identifier include instructions that when executed by the at least one processing device, control the tracking system to: select a first 2D image coordinate of the first group of 2D image coordinates; for each remaining 2D image coordinate of the first group of 2D image coordinates, determine a distance between the remaining 2D image coordinate and the first 2D image coordinate; select five remaining 2D image coordinates having shortest distances to the first image coordinate from among the determined distances; and determine whether a first candidate set that includes the first 2D image coordinate and the selected five remaining 2D image coordinates includes a first sub-set of 2D image coordinates that form a first straight line and a second sub-set of 2D image coordinates that form a second straight line, and wherein responsive to a determination that the first candidate set includes a first sub-set of 2D image coordinates that form a first straight line and a second sub-set of 2D image coordinates that form a second straight line, generate the first tag identifier by using the 2D image coordinates of the first candidate set.
