Problems solved by technology

Among them, gesture sensing technology based on sound signals is easily affected by environmental noise, and the gestures that can be recognized are limited; gesture sensing technology based on human body sensors often requires users to wear related sensors, which is unfriendly to users; radio frequency signal-based Gesture perception technology is more sensitive to the environment, and the system implementation scene layout is more troublesome

Abstract

The invention discloses a sign language recognition system based on sensing equipment and a working method of the sign language recognition system. The working method comprises the following steps: collecting joint point data of hands of a user in real time; performing noise reduction on the joint point data; segmenting the articulation point data after noise reduction to complete gesture action segmentation; calculating gesture features used for gesture classification; gesture features corresponding to the gesture actions are classified, and the types of the gesture actions are determined; and matching the sign language corresponding to the gesture action category, and displaying a sign language result. On the basis of gesture action modeling and gesture classification, an online sign language recognition system is designed and developed, and a solution is provided for communication between healthy listeners and deaf-mutes.

Description

technical field [0001] The invention belongs to the technical field of gesture perception and sign language recognition, and in particular relates to a sign language recognition system based on a sensing device and a working method thereof. Background technique [0002] In society, there is a group of people who cannot hear or speak, and can only live in a silent world. They are the tens of millions of deaf-mute people in our country, who cannot communicate like normal people. Their living conditions such as work, study, and medical treatment have brought great troubles. In real life, they also have a means of communication—sign language, but most hearing people cannot understand the meaning of sign language. For this reason, gesture sensing technology has been extensively studied. At present, gesture sensing technology can be divided into four categories according to sensing means, namely, gesture sensing technology based on sound signal, gesture sensing technology based ...
