Simulation of thermal radiation image processing based on optical technology in volleyball sports evaluation system: An image thermal model analysis

Abstract

As a high-intensity team sport, volleyball requires very high physical strength and skills of the athletes. Traditional evaluation methods often rely on the subjective judgment of coaches and simple physiological indicators measurement. The research plan is to develop a thermal radiation image processing method based on optical technology and apply it to the simulation of volleyball evaluation system. In this study, optical imaging technology is used to capture thermal radiation images of athletes in a non-contact way. These images are then analyzed through a series of image processing algorithms, including image enhancement, noise removal, edge detection, and feature extraction. In order to analyze the thermal radiation image more accurately, we construct an image thermal model, which is based on the principles of thermodynamics and optics, and can simulate and predict the thermal energy distribution of athletes in different motion states. The simulation system is used to simulate volleyball match and training scene, and the thermal radiation image processing method and image thermal model are applied to the system. The experimental results show that the thermal radiation image processing method in this paper can effectively separate the thermal radiation image of athletes from the complex background, and accurately extract the key features. The simulation results of the image thermal model are in good agreement with the actual measurement data, which can accurately reflect the heat energy distribution and consumption of athletes under different exercise intensities. The simulation system successfully simulates volleyball games and training scenarios, providing intuitive evaluation tools for coaches and sports science experts.
