Center-of-gravity position estimation device, center-of-gravity position estimation method, and program

摘要

PROBLEM TO BE SOLVED: To provide a technique for accurately estimating a three-dimensional center-of-gravity position of a human body from a multi-view image even when there is a region that cannot be observed by a camera. A three-dimensional model generation unit that generates a three-dimensional model at time t from multi-view images, a three-dimensional joint position estimation unit that estimates joint position coordinates at time t from the multi-view images, and three-dimensional at time t A weighted three-dimensional model generation unit that generates a weighted three-dimensional model at time t from the model and the joint position coordinates at time t, a weighted three-dimensional model at time t, and a part identifier i at a time before time t And a three-dimensional center-of-gravity position estimation unit that estimates the three-dimensional center-of-gravity position at time t from the part three-dimensional center-of-gravity position and the weighted three-dimensional model at a predetermined time.
