Method for capturing movement based on multiple binocular stereovision

Abstract

The invention discloses a movement capturing method based on multiple binocular stereo vision. A movement video collecting device is constructed, and human movement video sequences from different orientations are collected by the movement video collecting device. Multiocular movement video sequences shot by a plurality of cameras are calibrated. Marked points matching and tracking of each binocular tracker is finished. Data fusion of three-dimensional tracking result of multiple binocular trackers is completed. The three-dimensional movement information of the marked points acquired by a multiocular fusion device is fed back to the binocular tracker to consummate binocular tracking. On the basis of binocular three-dimensional tracking realized by binocular vision, the invention fuses multiple groups of binocular three-dimensional movement data, resolves parameter acquiring problem of three-dimensional position, tracking, track fusion and the like for a plurality of marked points, increases number of traceable market points and enables the tracking effect to be comparable with three-dimensional movement acquiring device employing multi-infrared cameras for collecting.

Description

technical field [0001] The invention relates to the field of electronic information technology, especially the field of computer vision. Background technique [0002] Motion capture technology is a high-tech widely used in the world. Motion capture technology is to place sensors on each joint of the performer. When the performer makes an action, the capture device will detect and record the movement trajectory of the performer's joints in three-dimensional space, and convert it into a digital "abstract movement". . These motion data can be used to drive different character models, so that these character models make exactly the same movements as the performers, thereby realizing motion reproduction on the computer, and finally generating animation sequences. [0003] At present, motion capture technology has been fully used in related industries such as film and television advertising and game production. It has the characteristics of high speed, high quality, and extreme ...

Problems solved by technology

However, using color blocks as marking points is prone to deformation in 3D vision and there are differences in imaging hues between different cameras, which will lead to inaccurate tracking, and when the number of marking points increases, the colors that can be clearly distinguished are limited.

These problems prevent the practical application of this method
