Fitness compensatory evaluation method based on Openose and binocular vision

Abstract

The invention discloses a fitness compensatory evaluation method based on Openose and binocular vision, and belongs to the field of fitness compensatory evaluation. The method includes: constructing ahuman sport event-sport mode-compensatory fitness basic library; capturing the human skeleton information by using two ordinary RGB cameras and an OpenPose human skeleton model library to obtain thetwo-dimensional coordinates of the joints of a human body in different coordinate systems; calibrating the two RGB cameras to realize the conversion and fusiong of the human skeleton data under the two cameras so as to obtain its three-dimensional motion data in a world coordinate system; extracting an abnormal motion characteristic value according to a human kinematic model with known kinematic parameters, and obtaining a fitness compensatory evaluation result having three dimensionalities including the degree of freedom compensation, activity compensation, and activity coordination compensation according to a matching result of the abnormal motion characteristic value and a standard motion characteristic value. The method effectively reduces the subjectivity and arbitrariness of the evaluation process, and improves the comprehensiveness and scientificity of the compensatory evaluation.

Description

technical field [0001] The invention belongs to the field of fitness compensation assessment, and more particularly relates to a fitness compensation assessment method and system based on OpenPose and binocular vision. Background technique [0002] Fitness compensation refers to the function of the body mobilizing other undamaged or less damaged limbs to replace or compensate for the severely damaged limbs when a certain part of the body is damaged. Many studies have shown that fitness compensation will greatly affect the recovery of damaged limbs, seriously affect the reconstruction of the normal movement pattern of the human body, and be extremely detrimental to the stability, symmetry and coordination of the human body's movement, and even cause damage to the damaged limbs. further decline in functionality. Therefore, how to correctly assess fitness compensation and inhibit fitness compensation has always been a key issue in stroke medical rehabilitation. [0003] At pr...
