Binocular stereo vision-based guide eyeglasses for blind person

Abstract

The invention discloses binocular stereo vision-based guide eyeglasses for a blind person. The binocular stereo vision-based guide eyeglasses comprise special glasses (1), a main control box (2), a vibration waistband (3), a headphone line (5), an earplug (6), a video cable (4) and a battery. After power-on, an image acquisition module (8) configures image sensor parameters of two micro cameras (7) and simultaneously collects image data, the image data is transmitted to the main control box (2) through the video cable (4) and then is processed, a headphone broadcasts information to the blind person and simultaneously transmits the information to the vibration waistband (3), a vibration control module (10) controls the vibration of a waistband motor (11) to remind the blind person to pay attention to the front obstacle, and a user can use a dedicated dialing keyboard (9) to realize speed dial. The binocular stereo vision-based guide eyeglasses for a blind person has high detection accuracy,, a wide range, fast frequency, wearing convenience, light weight, long duration time and a wide application prospect.

Description

technical field [0001] The invention relates to a guide glasses, in particular to a guide glasses based on binocular stereo vision. Background technique [0002] Guide glasses are worn by the blind or visually impaired to provide navigational aids for self-walking, which belongs to a blind-guiding device. Traditional guide glasses mainly use ultrasonic ranging, infrared ranging or micro-radar ranging. The ranging sensor installed on the glasses senses the object in front, and sends out a warning sound or vibration to remind the blind according to the distance of the object. The disadvantage is that the information is single and the sensor The distance information of obstacles in one direction can only be measured, and the beam angle of the ultrasonic ranging sensor leads to poor measurement accuracy, while the radar has the disadvantage of high cost. Camera-based guide glasses are mainly used to identify objects, without distance information, and do not know the distance of...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of guide glasses based on binocular stereo vision, which solves the problem that traditional blind guide equipment has little measurement information, lacks distance information, or has distance information but cannot be practical due to the huge equipment
