Title:
CORRECTION PORTION PRIORITY ORDER GENERATION METHOD, CORRECTION PORTION PRIORITY ORDER GENERATION DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/243044
Kind Code:
A1
Abstract:
On the basis of video data of a practicing motion and a target motion, a data generation unit 111 extracts a plurality of key frames and joint coordinates in each of the key frames, and extends practicing person data that serves as joint coordinates of a practicing person. On the basis of joint coordinates of a practicing motion, joint coordinates of a target motion in each of the key frames acquired by the data generation unit 111, and joint coordinates of the practicing motion after data extension, a measure learning unit 112 observes joint coordinates (posture state) St of the practicing motion in each of the key frames, selects a joint portion at to be corrected in accordance with a measure π learned through reinforcement learning in a posture state St of the observed practicing motion, calculates, by a weighted sum between a reward rt E indicating the performance of the practicing person and a reward rt M indicating a correction quantity (distance between the target motion and the practicing motion), a reward rt+1 in a case when a transition is made to a next posture state St+1 by correction of the selected joint portion at, and performs reinforcement learning of the measure π such that a cumulative reward R becomes maximum. In accordance with the learned measure π, one joint portion to be corrected by the practicing person is outputted.
