Sign language recognition method and system based on sign language gloves

Abstract

The invention discloses a sign language recognition method and system based on sign language gloves. Ten fingertips and fingers of the sign language gloves are different in color; the palm and the back of the gloves are different in color; the wrist parts of the two gloves are different in color; a bending sensor is arranged at finger bending parts; a rotation sensor is arranged at the wrist parts; a data communication module is arranged on the gloves to transmit data between the gloves and a sign language recognition system. The sign language recognition method comprises the following steps of: preprocessing the finger bending data and the palm rotation angle data by the sign language recognition system; grouping the processed data with all of characteristic values to obtain matching sequences; matching the matching sequences with data stored in a sign language digital standard library; converting the matched results to recognizable output signals; and transmitting the output signals to an output terminal to complete sign language recognition. The sign language recognition method and system provided by the invention can improve the sign language recognition accuracy by using the sensors and image recognition.

Description

technical field [0001] The invention relates to pattern recognition in the field of artificial intelligence, in particular to a sign language recognition method and system based on sign language gloves. Background technique [0002] There are currently two types of gesture recognition, one is a gesture recognition method based on sensor data, and the other is a gesture recognition method based on image recognition. [0003] Gesture recognition based on physical glove sensor data is to directly obtain finger movement feature data from the sensor, and translate it into words or sounds that can be directly recognized by humans through a certain algorithm; gesture recognition method based on image recognition is to use the image input device to input the hand into the In the computer, the method of gesture recognition with the help of image processing technology. [0004] Scientists at home and abroad have done a lot of research on gesture recognition based on image recognition...
