Assignee: THE UNIVERSITY OF TOKYO
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method of obtaining joint positions of a subject with an articulated structure, said subject having a plurality of feature points in the body of said subject including a plurality of joints wherein a distance between adjacent feature points is obtained as a constant,
obtaining a spatial distribution of a likelihood of a position of each feature point based on a single input image or a plurality of input images taken at the same time;
obtaining one or a plurality of position candidates corresponding to each feature point based on the spatial distribution of said likelihood of the position of each feature point;
obtaining each joint angle by performing an optimization calculation based on inverse kinematics using said candidates and said articulated structure; and
obtaining positions of the feature points including the joints by performing a forward kinematics calculation using said joint angles.
