Abstract
With the development and popularization of 3D technology, human behavior recognition has gradually developed from plane feature recognition to elevation feature recognition. In the process of collecting motion characteristics, the research on skeletal muscle will lead to a series of data in time series, which is the basis of sports biomechanics research and sports training. Some important semantic information such as centerline and joint center can be obtained by further data processing. The results of the study showed that the three-dimensional coordinate positions of the femur and pelvic attachment points of the muscles surrounding the hip joint from the pelvis were measured and positioned. A 3D model is built to simulate the human skeletal model subjected to speeds of 3 and 7 m/s, and different motion velocities can exhibit different motions. The research in this study shows that using 3D technology and comprehensively utilizing the expertise of biomechanical analysis and graphical modeling to study the mechanical properties of bone joints and soft tissues provide new ways and methods.

Introduction e3D visualization technology of data human body is an important research direction in the field of virtual human modeling
One is to mark some locations to capture the action. e second is to reconstruct three-dimensional information from a two-dimensional image sequence [9]. e third method is to use a ranging sensor to describe the motion by distance. e extraction of data on bone and the joint center has become a research hotspot [10]. e extraction of human bones and joint centers based on point cloud data is processed by processing the point cloud data of the real human body acquired by the three-dimensional scanner, thereby extracting semantic information such as the skeleton and joint center of the human body model [11,12,13]
Musculoskeletal systems need to be simulated, and these local simulations need to be integrated into the whole human motion for comprehensive analysis
Summary
Musculoskeletal systems need to be simulated, and these local simulations need to be integrated into the whole human motion for comprehensive analysis. E 3D model of point cloud data based on scanning technology can vividly reproduce the personalized shape information of the human body. It is an accurate and reliable representation method of virtual human geometry. E specific process is as follows: in the voxel model, the pixel of a certain point has a certain distribution relationship with its neighboring pixels According to this feature, certain rules can be drafted to filter it, the redundant information is gradually removed, and the center pixel is retained. E method has been gradually applied to many disciplines such as bioengineering and medicine in combination with 3D reconstruction technology and other virtual reality technologies and has become an important experimental method in the field of biomechanics It can effectively analyze the physical properties of the human body. E basic idea of the method of directly judging the joint based on the registration image is to register the image as a
