RETRACTED ARTICLE: Image acquisition system based on optical sensors for swimmer technical analysis and simulation

Effective physical training is the necessary condition to achieve good physical training effect and greatly improve the level of physical competition. Therefore, it is necessary to take scientific and reasonable technical means to carry out systematic and effective supervision and management to ensure the effectiveness of training. This paper first analyzes the leg movement of swimmers, and defines the different intensity of swimming. After careful study, an image acquisition system based on light sensor is designed and developed for technical analysis and simulation of swimmers. The research uses advanced light sensor technology to design an image acquisition system that can record various movements of swimmers in the water in real time and convert them into digital data. By establishing a set of effective algorithms, these data are analyzed and simulated accurately. The experimental results show that the image acquisition system can accurately record swimmers' movements, and accurately analyze and simulate their technical performance. Compared with the traditional technical analysis method, the system in this paper is not only more accurate, but also can provide more comprehensive data support, which can effectively improve the accuracy and credibility of technical analysis, and has great significance for the improvement of swimming training and competitive level.
