Embodiment Construction

[0072] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but this does not constitute a limitation of the present invention.

[0073] The whole body motion capture system and method of the present invention are mainly for single human body object and motion capture in indoor environment. figure 1 The five-step composition of the motion capture method of the present invention is given: multi-camera synchronous shooting to obtain video images of human objects (101), reconstruction of three-dimensional body data (three-dimensional point cloud, three-dimensional optical flow) from multi-camera video image data (102) , motion capture initialization (103), three-dimensional skeleton pose estimation and tracking (104), and the virtual character being driven to move synchronously by the obtained pose motion data (105).

[0074] Human whole body motion is defined as the skeleton posture movement of the three-d...

Abstract

The invention discloses a vision-based real-time general movement capturing method and system for a human body. The vision-based real-time general movement capturing system comprises a multi-camera synchronous acquisition unit used for acquiring interested three-dimensional space scene video streaming, a real-time three-dimensional body and three-dimensional movement flow reconstructing unit used for reconstructing the three-dimensional body and whole-body three-dimensional movement flow information of the human body object in real time, a whole-body pose estimating and tracking unit used for estimating and tracking the three-dimensional general movement pose of the human body in real time, and a display unit using movement data to drive virtual characters in real time, wherein the display unit is used for using captured skeleton pose data to drive virtual characters in real time and displaying in a display device. The vision-based real-time general movement capturing method and system for the human body use a non-contact computer vision method, the real-time acquisition for the whole-body skeleton pose data and the real-time virtual character drive can be realized without an extra wear marking device, and compared with common action capturing technology and equipment, the vision-based real-time general movement capturing method and system for the human body are easy and convenient to realize.

Description

technical field [0001] The invention relates to the field of electronic information science, in particular to a vision-based real-time whole-body motion capture method and system thereof. Background technique [0002] Human motion analysis is one of the hot issues in computer graphics and computer vision research. The reason for this is that human motion data are used in many fields of entertainment and human-computer interaction. For example, in many video games or computer animations, human body motion data is often used to drive virtual characters, making the movements of virtual characters natural and lifelike; tracking and recognition of human body motions such as gestures can convert human body postures, gestures and other actions into certain computer commands, as a way of human-computer interaction; the third major application is in medical and sports, such as gait analysis is the observation and analysis of human body movements, body mechanics, and muscle activity ...
