AI Technical Summary

Problems solved by technology

[0005] The vision-based sign language recognition system is limited by the technical capabilities of computer vision. It is very difficult to detect the front-end hand shape, and the recognition is greatly affected by the background and light. Therefore, the current vision-based sign language recognition system can only achieve limited sign language recognition.
[0006] Data gloves combined with motion sensors can easily obtain more accurate sign language data, and can already realize sign language recognition with a large vocabulary, but the cost of data gloves is very high, which seriously limits the popularization and application of the technology

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0038] figure 1 It is a schematic diagram of the phalanx and the side of the phalanx related to the finger motion coding of the present invention. When the palm faces the person and stands upright, the phalanxes from top to bottom are respectively the first phalanx, the second phalanx, and the second phalanx. Three knuckles, among them, the thumb does not have a third knuckle; for each knuckle, the direction of the side of the thumb is the outer side, the direction of the little finger side is the inner side, the direction of the palm side is the front side, and the direction of the palm side is the front side. The direction of the back side of the hand is the back side, which are respectively four sides of a knuckle, inc...

Abstract

The invention relates to finger motion coding and a mapping method between finger motions and Chinese phonetic alphabets, and relates to the coding technology; aiming at finger motions, the method codes, and matches the codes with the Chinese phonetic alphabets, thus forming the mapping method between finger motions and Chinese phonetic alphabets. The method uses coding and mapping so as to simplyand accurately map the finger motions on the corresponding Chinese phonetic alphabets, thus building a deaf-mute sounding apparatus with a low cost.

Description

technical field [0001] The invention relates to the field of coding technology, in particular to a finger motion coding technology and its mapping technology with Chinese Pinyin. Background technique [0002] Sign language is a special language that relies on movement and visual communication, and it is a tool for deaf people to communicate. Sign language is composed of the combination of hand shape, position, direction, facial expression, lip movement, and body gesture information. Learning sign language can improve the living, learning and working conditions of deaf-mute people. Learning sign language for normal people can provide better services for deaf-mute people. services. However, Chinese sign language contains more than 3,000 commonly used words, which makes learning sign language require a lot of time and great effort, which hinders the normal communication between normal people and deaf-mute people. [0003] With the popularization of computers and the developme...
