Light-reflecting type mobile sign language recognition system and finger-bending measurement method

Abstract

The invention discloses a light-reflecting type mobile sign language recognition system and a finger-bending measurement method. The system is characterized by comprising a finger-bending data glove (1), an advanced RISC machine 7 (ARM7) microprocessor (2) and a speech synthesis output module (3), wherein a power input end of a photoelectric sensor (1-2) of the finger-bending data glove (1) is connected with a power supply end of the ARM7 microprocessor (2) by a power supply lead (1-3), and an output end of the photoelectric sensor (1-2) of the finger-bending data glove (1) is connected with a signal input end of the ARM7 microprocessor (2) by a measurement lead (1-4); the speech synthesis output module (3) consists of a speech synthesis chip (3-1), a power amplifier (3-2) and a loudspeaker (3-3); and an input end of the speech synthesis chip (3-1) is connected with an output end of the ARM7 microprocessor (2), and an output end of the speech synthesis chip is connected with the loudspeaker (3-3) by the power amplifier (3-2). The light-reflecting type mobile sign language recognition system is simple in structure, low in cost, convenient to carry about and beneficial to improving the living, study and work conditions of deaf-mute disabled persons.

Description

technical field [0001] The invention relates to a sign language recognition system and its realization method, in particular to a light reflection mobile sign language recognition system and a finger bending measurement method. It belongs to the field of science and technology. Background technique [0002] Sign language is a body movement language that expresses meaning through hand movements, and is mainly used for communication between deaf and dumb people. According to statistics, there are currently about 24 million deaf-mute people in China who suffer from hearing and language impairments. The communication between them and between them and normal people is mainly carried out through Chinese sign language. As early as the late 1950s, in order to care for the deaf and mute and promote communication between them, the Chinese government began to standardize sign language for the deaf and mute in China. [0003] The purpose of sign language recognition is to automaticall...
