Embodiment Construction

[0025] A specific implementation process of the present invention will be described below in conjunction with the accompanying drawings.

[0026] The human body motion track detection method that the present invention proposes comprises the following steps:

[0027] 1) Paste the mark points: Paste the mark points 2 on the surface of the part to be detected of the detected person 1, such as figure 1 shown. In order to solve the problem that the automatic identification and tracking success rate of marker points is low due to the same color of marker points due to small spacing or cross-moving parts, markers of different colors are pasted on these sensitive parts. Paste different colors on the parts where the distance between adjacent marker points is small or where there is cross movement of the detected human limbs, and the color of the marker points is different from the background color of the paste surface. For example, the distance between the two marker points on the an...

Abstract

A method for detecting the moving trace of human body includes such steps as sticking the color markers at the positions on human body, walking on the ground while taking the images of walking procedure by color camera, transmitting the images to computer, recognizing and tracking the markers by program, and data analyzing.

Description

technical field [0001] The invention relates to a detection method for identifying and tracking colored marker points pasted on main parts of a human body by an image processing method to obtain a human body movement track, and belongs to the technical field of gait analysis in biomedical engineering. Background technique [0002] Walking is the most common behavior process in people's daily life, and the detection device of human body motion trajectory is a special device for recording and analyzing human walking rules. At present, there are two main types of human body motion trajectories in clinical application: the first is to use the electronic goniometer to detect the change of joint angle to obtain the law of human motion; the second is to capture the image of human motion and paste it on the joint. The human body motion trajectory detector that obtains the human body motion law through the marker points. The first method needs to install angle sensors on both sides ...
