Thermal radiation image based on optical sensors for collaborative training simulation of football players: Thermal energy consumption simulation☆

In modern football training, physical fitness is not only related to the individual performance of athletes, but also directly affects the cooperative combat ability of the whole team. An image analysis method of thermal radiation based on optical sensor was developed to simulate the thermal energy consumption of football players during cooperative training. The first deployment was an array of high-precision optical sensors that were able to capture information about the thermal radiation on the surface of the athlete's body. Sensors are installed at multiple angles of the training field to ensure full coverage of the athlete's movement area. The optical sensor captures the thermal radiation data in real time and generates the thermal radiation image when the football players are cooperating in training. These images can reflect the changes in body temperature of athletes during different training phases. After the thermal radiation image is preprocessed, the image analysis software is used for processing. We extracted key features in the images, such as hot spots, temperature gradients, etc., and correlated these features with the intensity and duration of the athletes' exercise. Based on the results of thermal radiation image analysis, combined with the physiological parameters and training data of athletes, we set up a heat energy consumption model. The thermal energy consumption model established by us is in good agreement with the actual measurement data in most cases, which can provide scientific guidance for the physical training of football players.
