Abstract

Disclosed is a human motion capture method based on unsynchronized videos, which can effectively recover the 3D motion of a target person through multiple unsynchronized videos of the person. In order to utilize multiple unsynchronized videos, the present disclosure provides a video synchronization and motion reconstruction method. The present disclosure is implemented in the following steps: synchronizing multiple videos based on a 3D human pose; performing motion reconstruction based on synchronized videos, modeling the motion difference across different viewpoints by using the low-rank constraint to realize high-precision human motion capture from the plurality of unsynchronized videos. According to the present disclosure, more accurate motion capture is carried out by using multiple unsynchronized videos.
