Thermal radiation imaging and optical imaging detection Application in real-time monitoring of physiological status of long-distance runners: Real-time thermal imaging monitoring

Abstract

Long-distance running, as a sport with high demands on cardiopulmonary function and endurance, puts forward higher demands on athletes’ physical fitness and physiological state. This paper discusses the application potential of thermal radiation image and optical imaging technology in the real-time monitoring of long-distance runners physiological state, especially the real-time thermal imaging monitoring technology. The study uses high-precision thermal imaging camera and optical imaging equipment to acquire real-time thermal radiation images and optical images during the training and competition of long-distance runners. The thermal radiation image is preprocessed to improve the image quality. Then image analysis technology was used to extract key physiological parameters, and combined with athletes’ training intensity, ambient temperature, humidity and other data, the rule of body temperature changes reflected in thermal radiation images was analyzed, as well as the relationship between these changes and athletes’ physiological state. Based on the above analysis results, a real-time thermal imaging monitoring system is developed. The system can display the temperature distribution map of athletes in real time and give early warning to the physiological state of athletes according to the set threshold. The study found that in the process of long-distance running, the athlete’s body temperature will rise with the increase of exercise intensity, especially in the stage of greater cardiopulmonary function load, the temperature rise is more obvious. Through the analysis of thermal radiation images, the hot spots on the athlete’s body surface are successfully identified. These areas usually correspond to the active parts of blood circulation, and can be used as an important indicator to evaluate the physiological state of athletes.
