A method for distinguishing the crowd with balance disorder based on the center of gravity shift model

Abstract

The invention discloses a method for distinguishing the crowd with balance disorder based on a center of gravity shift model. The method comprises the following steps: firstly, human walking posture video of a normal person and an abnormal person in a built virtual reality scene is collected from 45 DEG; then, the video of normal person and abnormal person is loaded, the video image is extracted into pictures, and then the pictures are processed to obtain the barycenter coordinates of normal person and abnormal person respectively, finally, according to the center of gravity data, the center of gravity angle data and the mean and variance of the upper and lower center of gravity of human body are extracted, and the center of gravity data are classified by SVM classifier, and then combinedwith the center of gravity angle data and the mean and variance of the upper and lower center of gravity of human body, the balance ability disorder crowd is quickly judged. The method disclosed by the invention solves the problems that the traditional subjective method is too coarse and the gauge evaluation method is too complex and the cost is too high, and the video and the image are processedthrough a plurality of steps, and the final classification accuracy rate is above 85%.

Description

technical field [0001] The invention belongs to the technical field of computer digital image processing, and relates to a method for distinguishing people with balance ability impairments based on a center-of-gravity offset model. Background technique [0002] The balance ability of the human body refers to the ability of the human body to maintain its own stability and resist disruption of balance, including the ability to maintain a certain posture or the ability to regulate the body to maintain balance when subjected to external forces. It is one of the important physiological functions of the human body. The main factors affecting the balance ability are the support area, the height of the center of gravity, the weight and other factors, and it is also affected by the vision, body organs, and the response of the sensory system. Possessing a good balance ability is conducive to improving the function of motor organs and vestibular organs, improving the central nervous sy...
