Motion recognition method and device, electronic equipment and storage medium

The invention discloses an action recognition method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining a target video segment, andrecognizing an object center point position, a human body joint point position and a hand joint point position of each frame of image in the target video segment; constructing an undirected space timegraph corresponding to the target video segment according to the object center point position, the human body joint point position and the hand joint point position of each frame of image; and basedon the undirected spatial time graph, extracting spatial-temporal features of the target video segment, and inputting the spatial-temporal features into a classifier so as to complete action recognition. According to the action recognition method provided by the invention, the human body joint point positions and the hand joint point positions are used for describing the human body skeleton, action recognition is carried ou
