Action sequence recognition and intention inference method and device, equipment and storage medium

The invention relates to an action sequence recognition and intention inference method and device, equipment and a storage medium, and aims to realize intention inference of an action sequence and further improve effectiveness and applicability of intention inference. The action sequence recognition and intention inference method comprises the steps that an action sequence containing a plurality of discrete actions is obtained, and the action sequence comprises an RGB image sequence, a depth image sequence and a skeleton image sequence; generating a pseudo video image according to the RGB image sequence and the depth image sequence, and generating a pseudo skeleton image according to the skeleton image sequence; inputting the pseudo video image and the pseudo skeleton image into a semantic feature extraction neural network model, and extracting high-level semantic features of a plurality of discrete actions; inputting the pseudo skeleton image into an association feature extraction neural network model, and e
