Study on the Movement Posture and Sports Characteristics Based on the 3D Reconstruction of Human Body

With the development of computer technology, 3D simulation and digital technology has been used in sports training. It will help athletes to master the technical essentials in the training process, greatly improve training efficiency and reduce the possibility of injury. In this paper, the author analyzes the movement posture and sports characteristics based on the 3D reconstruction. Through the human body movement tracking, we can segment the motion steps and establish the overall motion trajectory. At the same time, through the human skeleton model, we can analyze the movements of each part of the body, including the translational and rotational degrees of freedom.
