Method and device for obtaining video human motion

Abstract

The present application discloses a method and a device for obtaining video human body movements. The method comprises the following steps of: acquiring calibration information of a camera; acquiringvideo information photographed by a camera, wherein the video information comprises a plurality of different unique identification points of an encoded pattern, the identification points being arranged on a target part of a human body for marking a moving state of the target part of the human body, each encoded pattern comprising at least four feature points; obtaining target information of an identification point, wherein the target information comprises at least: a coding pattern of the identification point and spatial structure information of the coding pattern; according to the calibrationinformation and the target information of the marking point, the video information is reconstructed to obtain the spatial posture of the marking point in the camera coordinate system, so as to determine the movement of the target part of the human body. In the related art of human motion capture, the invention solves the technical problems that the motion capture system cannot simultaneously giveconsideration to the simple structure, the convenient operation and the accurate motion reconstruction.

Description

technical field [0001] This application relates to the field of motion capture, and in particular, to a method and device for acquiring video human motion. Background technique [0002] Traditional motion capture systems include electromagnetic, mechanical, and optical, among which optical is the most mature and commonly used capture system in recent years. There are a wide range of applications in production and other fields. [0003] The characteristic of this type of system is to use special markers to mark the target, and to accurately measure the movement information of the target through a multi-camera array based on the principle of stereo vision. It has the advantages of high precision and accurate motion reconstruction. However, due to the large and complex system and the large amount of installation work, it can usually only be used in a fixed studio, and has high requirements for ambient light. The site cannot be directly exposed to the sun, and the site is refle...
