Abstract

The invention discloses a motion capture method for a binocular vision image based on background modeling. By the method, a human body serving as a foreground can be divided and the upper torso of the human body is subjected to motion capture simultaneously so as to achieve the effect of man-machine interaction. The method comprises the following steps of: on the basis of background modeling, establishing a Gaussian model for a clean background acquired by a camera, comparing an acquired video with a background model, providing a probability value which belongs to the foreground or the background for each pixel of a scene through depth information acquired by a binocular camera, and dividing the foreground and the background of the scene through an image cutting algorithm. When the divided foreground is the upper torso of the human body, a basic skeleton model of the human body is acquired by refining a foreground profile, de-noising and determining a key point so as to complete the motion capture process.

Description

technical field [0001] The invention belongs to the field of computer vision technology and digital interactive entertainment, and relates to a background segmentation and motion capture process completed by using a binocular camera and background modeling technology. Background technique [0002] Motion capture technology refers to the use of computer vision or other means to capture the movement of the human body in real time and accurately. With the development of computer software and hardware and the improvement of computer users' needs, the role of motion capture technology in digital entertainment, video surveillance, motion analysis and other fields has become more and more obvious. [0003] However, the development of motion capture technology is also restricted by various conditions and there are many limitations. For example, changes in light, complex backgrounds, and occlusion during motion. These factors make the process of motion capture more difficult. Howe...
