Kinematics Analysis of Aerobics Movement Decomposition Based on Multi-target Video Tracking Algorithm

Abstract

AbstractComputer vision is currently an important research field. In computer vision, target tracking is one of the entry points for research, it is widely used in motion analysis, video surveillance, robot navigation, human–computer interaction and many other fields. In so many application scenarios, target tracking algorithms are required, it has high durability and efficiency. However, in real complex scenes, there are often different situations such as light changes, mutual occlusion between targets, interaction between targets, and blurred target motion, making the recorded video scene complex and changeable. Therefore, it is still a very difficult task to effectively monitor multiple moving targets at the same time. This article explores and analyzes the aerobics movement decomposition kinematics based on the video tracking algorithm of multiple sports targets. After consulting related materials, summarizes the feasibility of the aerobics movement decomposition kinematics based on the multiple sports target video tracking algorithm. The experiment of aerobics action decomposition kinematic analysis of the motion target video tracking algorithm, through the experiment, it is concluded that the angle of the right hip joint is 167.45°, when the right hip is fully extended at the beginning of the set of competitive aerobics action. It can be seen from the angle of the two knee joints that the legs are relatively straight and maintain a good posture. When the jumping foot hits the ground, the difference between the right hip angle between the two moments is 29.8°, that is, the right hip angle decreases and the right hip angle decreases, indicating that the upper body is facing the right side, the upper body begins to bend downward, and the left hip continue to abduct, its value increases, and at the same time the left lateral muscle stretches, so that the hip and shoulder joints form a larger rotation angle.KeywordsMultiple sports targetsTracking algorithmsAerobics movementsKinematics analysis
