Digital twinborn body construction method of human skeleton

Abstract

The invention discloses a digital twinborn body construction method for human skeletons, which comprises the following steps: acquiring data at important positions of a human body by utilizing VR (Virtual Reality) action capture and sensor technologies aiming at real human skeletons, and performing data classification, screening, reduction and calculation through artificial intelligence to obtainkey data; solving the key data through a human body reverse dynamics and biomechanics algorithm to obtain spatial orientation information and mechanical information of a target skeleton, fusing part of sensor data with a calculation result, then performing analogue simulation on the target skeleton, and obtaining the biomechanical property of the target skeleton and predicting the biomechanical property of the skeleton in an unknown posture by utilizing a plurality of prediction algorithms; and finally, performing modeling rendering on the performance data to obtain a high-fidelity digital twinning body of a real bone, thereby realizing loyalty twinning mapping of bone biomechanical properties. Under various human body action postures, the biomechanical property of the target skeleton canbe calculated in real time by utilizing the wearable VR equipment and a small number of sensors, and the real-time health detection of the target skeleton can be realized.
