Patent number: 11967101Abstract: The present invention provides a motion capture with a high accuracy which can replace an optical motion capture technology, without attaching optical markers and sensors to a subject. A subject with an articulated structure has a plurality of feature points in the body of the subject including a plurality of joints wherein a distance between adjacent feature points is obtained as a constant. A spatial distribution of a likelihood of a position of each feature point is obtained based on a single input image or a plurality of input images taken at the same time. One or a plurality of position candidates corresponding to each feature point are obtained based on the spatial distribution of the likelihood of the position of each feature point. Each join angle is obtained by performing an optimization calculation based on inverse kinematics using the candidates and the articulated structure.Type: GrantFiled: August 29, 2019Date of Patent: April 23, 2024Assignee: THE UNIVERSITY OF TOKYOInventors: Yoshihiko Nakamura, Wataru Takano, Yosuke Ikegami, Takuya Ohashi, Kazuki Yamamoto, Kentaro Takemoto
