Method for tracing three-dimensional human body movement based on multi-camera

Abstract

A three-dimensional human body motion trace method based on a multi-camera in the computer vision technical field has the following steps: firstly, tissue data points on the human body surface are picked up and outmost points are obtained through processing the tissue data; secondly, a standard three-dimensional skeleton model which is used for dynamic posture adjustment of the model during the trace process is established before skeleton pick-up and human body motion trace, thereby realizing fitting of the model and an original three-dimensional image; thirdly, a skeleton observation method is established and the skeleton model posture is adjusted according to the status that whether the number of the tissue points in each section of bone sleeve is maximal; fourthly, an implementation approach of optimal matching skeleton is established and the state that whether the current skeleton pose has met the trace requirements or not is judged through changing the space positions of root nodes and the angle of rotation of each boot section winding around the father node. The invention can quickly get the human body three-dimensional skeleton based on the existing human body tissue data, thereby realizing the human body motion trace.

Description

technical field [0001] The invention relates to a method in the technical field of telecommunications, in particular to a method for tracking three-dimensional human body motion based on a multi-eye camera. Background technique [0002] Three-dimensional human motion tracking is a hot and difficult point in the field of computer vision. Extracting human skeleton models from video data is a very effective monitoring and tracking method. The main application fields of human skeleton obtained from 3D voxel data are: surveillance system, virtual reality, advanced user interface, intelligent environment, entertainment, motion analysis, medicine, education, etc. The English word for three-dimensional voxel is voxel, which is the abbreviation of Volume Element. Voxel is called "voxel", which is equivalent to "pixel" in two-dimensional image--"pixel", which is the basic small element in three-dimensional space. The square contains information such as the X, Y, and Z coordinates of...

Problems solved by technology

3D human motion tracking is much more complicated than 2D

[0003] After searching the prior art literature, it was found that Caillette, F. et al. in 2004 in "Third IEEE and ACM International Symposium on Mixed and Augmented Reality" (IEEE and ACM third international symposium on mixed and extended reality) The published paper "Real-time markerless human body tracking using colored voxels and 3D blobs", (using colored voxels and 3D modules to track unmarked human bodies in real time) uses colored voxel information to track the human body, the The method needs to have a relatively good color contrast between the tracked target and the scene, which greatly limits its application in engineering
