Abstract: In order to improve the recognition accuracy of athletes' facial expression, a method of high jump athletes' facial expression recognition based on wearable multi-physiological parameter collection is proposed. Firstly, through the wearable multi-physiological parameter acquisition device, the device is used to collect the high jump athletes' heart rate, skin electrical activity parameters, body temperature and other multi-physiological parameters. Secondly, the baseline drift suppression method based on wavelet transform is used to suppress the baseline drift within multi-physiological parameter signals of high jumpers. Finally, the multi-physiological parameters of high jumpers without baseline drift are inputted into the convolutional neural network model, and the model is used to output the results of high jumpers' facial expression recognition. The experimental results show that the research method can accurately recognise the facial expressions of high jumpers, with the highest recognition accuracy of 99.21%.
