A multifunctional blind guide device based on binocular vision

Abstract

Provided is a multifunctional blind guiding instrument based on binocular vision. The multifunctional blind guiding instrument based on binocular vision is formed by a first camera module, a second camera module, an ultrasonic detection module, a GPS+ wireless transmission module with map information, an image processing module, a voice prompt module, a voice recognition module, and a power module. Therefore, the multifunctional blind guiding instrument conforms to a dominant design direction of a wearable multifunctional blind guiding instrument, and integrates functions of surrounding environment identification, barrier identification and positioning, barrier operation speed and distance identification, traffic light identification, GPS location, path planning, and humanized voice prompt. The blind guiding instrument is also integrated with functions of help and rescue.

Description

technical field [0001] The invention relates to the field of machine vision, in particular to a multifunctional blind guide device based on binocular vision. Background technique [0002] 90% of the information obtained by humans comes from the visual system, therefore, the loss of vision will seriously affect the quality of life. Blind people have great obstacles in their daily life because they cannot see, especially travel difficulties. [0003] There are currently many ways to guide the blind, such as non-visual detection methods such as blind sticks, infrared detection, and ultrasonic detection. However, these methods have certain disadvantages: [0004] ①. Use blind sticks to detect, the detection range is too small, blind people can judge the walking direction by touching the ground or surrounding objects, and whether they need to stop or not; this type of crutches has many disadvantages, especially it is difficult to find distant objects and objects suspended in m...

AI Technical Summary

Problems solved by technology

[0004] ①. Use blind sticks to detect, the detection range is too small, blind people can judge the walking direction by touching the ground or surrounding objects, and whether they need to stop or not; this type of crutches has many disadvantages, especially it is difficult to find distant objects and objects suspended in mid-air;

[0005] ② Using infrared, ultrasonic and other detection methods can only detect larger obstacles, and cannot obtain complete information such as obstacle contours and heights, so the security is poor

[0006] However, this blind guide reminds the blind through prompt sounds of different volumes, tones, rhythms or segmented voice prompts with large errors, which can only make the blind have a rough judgment on the distance of obstacles, and , consumes a lot of energy of the blind and easily leads to misjudgment
