Classification: CPC G | IPC G

Claim 10:
11. A system for obtaining joint positions of a subject comprising a memory and a processor,
said memory configured to store a file defining an articulated structure comprising a plurality of feature point in the body of the subject including a plurality of joints and a set of constants each defining a distance between adjacent feature points,
said processor configured to:
obtain 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;
obtain 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;
obtain each joint angle by performing an optimization calculation based on inverse kinematics using said candidates and said articulated structure; and
obtain positions of the feature points including the joints by performing a forward kinematics calculation using said joint angles.
