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 6):
The method of  claim 4 ,\n wherein the tracking system processor generating the first tag comprises:\n determining a first intersection coordinate of an intersection between the first straight line and the second straight line; \n determining a first cross ratio by using the three coordinates of the first sub-set and the first intersection coordinate; \n determining a second cross ratio by using the three coordinates of the second sub-set and the first intersection coordinate; \n determining a first vector cross product of the first straight line and the second straight line; \n responsive to a determination that the first vector cross product is a positive value, forming a first ordered pair that includes the first cross ratio as a first value of the first ordered pair and that includes the second cross ratio as a second value of the first ordered pair, wherein the first tag identifier is the first ordered pair; and \n responsive to a determination that the first vector cross product is a negative value, forming a second ordered pair that includes the second cross ratio as a first value of the second ordered pair and that includes the first cross ratio as a second value of the second ordered pair, wherein the first tag identifier is the second ordered pair.
