Method for distinguishing human body balance disorders based on gravity center area model under visual stimulation

Abstract

The invention discloses a method for distinguishing human body balance obstacles based on a gravity center area model under visual stimulation. The method comprises the following steps of firstly shooting a human body walking posture video of a normal person and an abnormal person in an established simulated reality scene according to an angle of 90 degrees with the front face when the human bodywalks; secondly, respectively extracting acquired walking posture videos of the normal person and the abnormal person into pictures, and respectively processing the extracted pictures to obtain upper,middle and lower gravity center coordinate data of the normal person and the abnormal person; and finally, judging and classifying the crowd with the balance ability disorder by combining the gravitycenter area data, the triangular area mean square error, the speed and the track route map. According to the method, the tumbler principle is used for explaining the crowd with the balance obstacle capability through the gravity center area deviation model, so that the balance capability of the crowd or other people is objectively judged, videos and images are processed through a plurality of steps, and the final classification accuracy is ensured to be 86% or above.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and relates to a method for distinguishing human balance disorders based on a center-of-gravity area model under visual stimulation. Background technique [0002] Human body balance ability is a kind of physical quality, which refers to the ability to resist the external force that destroys the balance to keep the whole body in a stable state, and is the basic ability of all static and dynamic activities. 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 balance ability are support area, center of gravity height, body weight and other factors, and it is also affected by vision, body organs, sensory system and other factors. When there is a balance disorder in the human body, there will be low...
