Thermal radiation image detection and optical motion capture in athlete physical health monitoring system simulation: Tissue thermal effects

Abstract

In the field of modern sports science, accurate monitoring of athletes’ physical fitness and health status is an important means to improve sports performance and prevent sports injuries. In this paper, an athlete physical health monitoring system combining thermal radiation image detection and optical motion capture technology is designed, and the effectiveness of the system is verified by simulation experiments. A monitoring system integrating thermal radiation image detection and optical motion capture technology is designed and built, including high sensitivity thermal camera, multiple optical capture cameras and corresponding data processing software. A group of representative athletes were selected as the research objects. The thermal camera captured the thermal radiation image of the athletes’ body surface in real time, while the optical capture system recorded the athletes’ movement track and posture. Then the thermal radiation images and motion data collected were analyzed by data processing software, and the surface temperature changes and motion parameters were extracted. Finally, statistical methods are used to process the experimental data to reveal the relationship between tissue thermal effect and motion heat transfer. The experimental results show that there are significant differences in body surface temperature distribution and change patterns when athletes perform different intensity and types of exercise. Through the thermal radiation image detection technology, the muscle region temperature of athletes increased significantly after high-intensity exercise, but gradually decreased during the recovery period. Optical motion capture technology provides accurate motion parameters, such as joint Angle, velocity and acceleration, which are combined with thermal radiation image data to reveal the dynamic change of tissue thermal effect during motion.
