Research on kick motion before Sanda based on 3D wireless sensor network image

Abstract

The biomechanical analysis of the pushing kick in the conventional free combat was aimed at the crowds with different ages and different types of skeletal muscles. The analysis precision was low. Therefore, this article put forward the biomechanical analysis of push-kick of free combat based on 3D image. Three-dimensional image technique and Hill equation were used to construct the biomechanical model of muscles of free-combat athletes and describe the leg mechanics in the kicking process. Pattern system provides an up-to-date and authoritative fuzzy model, which is an intelligent recognition algorithm. Then, the image analysis was used to build the motion model of knee joint, so as to determine the dynamic equation of knee joint of pushing kick. Based on the above model, the characteristics such as the strike force of push kick, the peak characteristic of leg joint angular velocity and the joint torque were analyzed to achieve the biomechanical analysis of the pushing kick in free combat. Experimental data show that combined the proposed biomechanical analysis method with the traditional analysis method, the precision has improved by 47.69%. Meanwhile, it is suitable for the biomechanics analysis of different free combat crowds.

For the analysis of crowds with different ages and different types of skeletal muscles, the influence of height, weight, and muscle type is not considered. Thus, analytical accuracy is low. 1,2 Therefore, this article put forward the biomechanical analysis of push-kick of free combat based on 3D image. The stereoscopic multi-action decomposition of three-dimensional image is used to capture the slight mechanical change. Based on Hill equation, the biomechanics model of muscle of push-kick action is built. The mechanical description is carried out based on data changes of muscle biological model. Meanwhile, the motion model of knee joint is constructed through the image analysis, and the biomechanical equation is optimized.The biomechanical analysis model of push-kick actions based on three-dimensional images is built. The fuzzy normal form neural system is mainly divided into three parts: relational model, fuzzy neural network, and rule-based model. In this article, based on the "check-feedback-optimization of data quality control technology, the technology used in the data analysis of medical health, achieve fundamentally health big data quality control, this method is effective to solve the medical health data and analysis, and ultimately provide health big data using high quality data. The materials of relational model include theory and a large number of implementat...
