The invention discloses a traffic police command gesture recognition method based on a skeleton joint point sequence, and the method comprises the steps: collecting video clips of traffic police command gestures under different visual angles, different scenes and different speeds; secondly, detecting an image containing a traffic police based on an improved target detection algorithm, and outputting multiple frames of traffic police command action images containing a target frame and coordinate information of the traffic police; thirdly, extracting traffic police articulation point informationthrough an attitude estimation algorithm, and combining the traffic police articulation point information according to a time sequence to form an articulation point sequence; and finally, processingthe obtained body articulation point sequence when the traffic police directs the traffic by using a space-time diagram convolution model so as to identify the type of the traffic police command gesture action. According to the invention, stable, accurate and rapid identification of the traffic police command gesture in a complex scene can be realized.
