  • Body dynamics calculation method, body dynamics model and model data thereof, and body-model generation method
    Patent number: 8145440
    Abstract: A forward/reverse mechanics calculation of an accurate model of a human body having bone geometrical data and muscle/cord/band data is carried out at high speed. When a new skeleton geometrical model is given, a mapping between the new skeleton geometrical model and a pre-defined normal body model representing a normal body is defined to automatically produce a new body model.
    Type: Grant
    Filed: January 5, 2009
    Date of Patent: March 27, 2012
    Assignee: Japan Science and Technology Agency
    Inventors: Yoshihiko Nakamura, Katsu Yamane, Ichiro Suzuki, Kazutaka Kurihara, Koji Tatani

  • Method of processing passive optical motion capture data
    Publication number: 20030215130
    Abstract: In a method of processing passive optical motion capture data having: an image capture step for capturing synchronized multiple camera images of a subject with passive optical markers; a three-dimensional reconstruction step for obtaining a set of three-dimensional coordinates of the markers from the picked-up data; a labeling step for deciding temporal correspondence between the markers in the subsequent captures and, thereby, locating the body part of the subject to which the markers are attached; and a joint angle calculation step for deciding an angle of each joint of a kinematic model to which the motion of subject is projected, on the basis of a set of labeled markers and computing a posture of the subject, the labeling step and the joint angle step are coupled as a loop and are performed simultaneously.
