In order to solve the problems of low accuracy and poor robustness of traffic police dynamic gesture recognition, a ST-GCN based traffic police dynamic gesture recognition method is designed in this paper. The skeletal features of traffic police were extracted from space and time dimensions. By updating the graph attention matrix, the skeletal connectivity structure of traffic police was optimized to highlight the effective spatial features. Increase the time attention mechanism and strengthen the characteristics of the core movements in the learning gestures. The design model compares 8 types of gestures of traffic police in different scenarios, and the results show that: The ST-GCN traffic police gesture recognition network, which integrates spatio-temporal attention mechanism, achieves good recognition effect, with an average recognition accuracy of 88.82%, which is 5.79% higher than that of classical ST-GCN, which verifies the good performance of the proposed algorithm in traffic police dynamic gesture recognition.
