[0105] Example

[0106] At present, depth-based skeletal tracking technology processes depth data to establish the coordinates of various joints of the human body. Skeletal tracking can determine various parts of the human body, such as the hands, head, and body, as well as their location. However, ordinary cameras can only obtain two-dimensional information in space. The goal of this algorithm is to track human skeleton points in a two-dimensional video stream.

[0107] First as figure 1 As shown, define the relevant detection points and correlation diagrams of the human body, as shown in Table 1 and Table 2 below;

Abstract

The invention discloses a human body bone point tracking method and system in a two-dimensional video stream. The method comprises: a camera obtains a two-dimensional video stream, a foreground picture is obtained by a foreground extraction module, head point and neck point coordinates are obtained by a face detection module, a system determines whether the head point is in a screen or not, and otherwise, the face detection module carries out operation continuously; a human body is divided into a left part ROI and a right part ROI to carry out detection on other key points, and a shoulder point detection module is used for obtaining left shoulder point and right shoulder point coordinates; a hand point detection module obtains left hand point and right hand point coordinates; an elbow point detection module obtains left elbow point and right elbow point coordinates; and then statistics of credibility of all points is carried out and credible points are displayed.

Description

technical field [0001] The invention relates to the research field of image processing, in particular to a method and system for tracking human skeleton points in two-dimensional video streams. Background technique [0002] Human-computer interaction technology refers to the technology that realizes effective communication between humans and computers in a way that is convenient for people to use through computer input and output devices. Human skeleton point tracking technology is an important technology in the field of human-computer interaction. It can identify the movement of the human body with the help of infrared rays, and can track multiple parts of the human body in real time without using any external equipment for motion capture. It has broad application prospects in computer-computer interaction environment. The human skeleton tracking technology in the prior art is generally based on the framework of Kinect and PC host system. Kinect is mainly responsible for c...
