Abstract

The invention provides a dynamic sign language semantic recognition system and method based on a depth image. According to the system and the method, depth image video information of an operator is acquired; the video information is processed to obtain hand joint information, sign language words are analyzed through the joint information; inputting each word into a semantic analysis model; and judging whether the semantic expression is complete or not, and directly outputting or converting control commands to other control units when the intention expression is complete, so that the sign language actions are translated into characters, a machine or an operating system is controlled, and hearing impairment people can be better integrated into social life.

Description

technical field [0001] The invention belongs to the technical field of semantic recognition, in particular to a system and method for dynamic sign language semantic recognition based on depth images. Background technique [0002] In principle, sign language recognition control can be divided into binocular camera-based and depth image-based three-dimensional regression. In gesture analysis, only simple gesture recognition and simple sign language words are supported. Among them, based on the binocular camera, the method of calculating the depth information of the feature points of the object by simultaneously shooting the object with the binocular camera is used for image recognition, thereby analyzing the gesture information. The 3D regression scheme based on depth images mainly relies on the image captured by the depth camera for the gesture and the distance information between each point in the shooting scene and the depth camera to establish a 3D model of the gesture. G...
