Group tracking in motion capture
First Claim
Patent Images
1. A computer-implemented method of tracking a group of motion capture markers in a sequence of frames stored on a non-transitory tangible storage medium, the method comprising:
- establishing a group relationship among a plurality of motion capture markers in a current frame;
labeling said plurality of motion capture markers in said current frame as a group using said group relationship,wherein said plurality of motion capture markers in said current frame forms an inherent shape which is used in labeling markers in other frames, andwherein each motion capture marker in said plurality of motion capture markers is identified by its position in the inherent shape; and
labeling a plurality of unlabeled motion capture markers in a next frame using said group relationship and based on a shape analysis of the group to substantially minimize incorrect marker labeling.

20. A system for tracking a group of motion capture markers in a sequence of frames, comprising:
-
a reference group module, for generating a reference group of motion capture marker information about the group of motion capture markers; and a group trajectory labeling module, for generating labeled marker group trajectory data of the group of motion capture markers using said reference group of motion capture marker information, wherein the labeled marker group trajectory data of motion capture markers is based on a shape analysis of the reference group to substantially minimize incorrect marker labeling, wherein said group of motion capture markers forms an inherent shape, and wherein each motion capture marker in said group of motion capture markers is identified by its position in the inherent shape which is used in labeling markers in other frames. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)

28. An apparatus tracking a group of motion capture markers in a sequence of frames, comprising:
-
means for establishing a group relationship among a plurality of motion capture markers in a current frame; means for labeling said plurality of motion capture markers in said current frame as a group using said group relationship, wherein said plurality of motion capture markers in the current frame forms an inherent shape which is used in labeling markers in other frames, and wherein each motion capture marker in said plurality of motion capture markers is identified by its position in the inherent shape; and means for labeling a plurality of unlabeled motion capture markers in a next frame using said group relationship and based on a shape analysis of the group to substantially minimize incorrect marker labeling. - View Dependent Claims (29, 30, 31, 32, 33, 34)
