Method for human action recognition in human-machine interactive assembly scene

Abstract

A method for human action recognition in a human-machine interactive assembly scene is disclosed in this application, joint coordinate streams of skeleton joints are obtained under a human action from motion sensing devices; a starting position and an ending position of the action are positioned according to data change based on a threshold value to obtain information of joints; resampling of angle change is made on the information of joints to obtain coordinates of joints; the coordinates of joints are normalized, to obtain a sequence of skeletons forming an action; obtaining a vector direction of the upper limb, and the scene is classified to be a left-hand scene or a right-hand scene; training is made for human action recognition in the left-hand scene and the right-hand scene respectively; human action outputs of the left-hand scene and the right-hand scene are fused to realize action recognition in a human-machine interaction scene.
