Abstract

The invention discloses a pair of guide glasses based on binocular stereo vision, comprising: special glasses (1), a main control box (2), a vibrating belt (3), an earphone line (5), earplugs (6), a video cable ( 4) and battery; after power-on, the image acquisition module (8) configures the image sensor parameters of the two miniature cameras (7) and collects image data simultaneously, and then transmits to the main control box (2) through the video cable (4) for further processing. process; the information is broadcast to the blind through earphones, and the information is sent to the vibration belt (3) at the same time, and the vibration control module (10) controls the vibration of the belt motor (11) to remind the blind to pay attention to obstacles ahead; the user can use the special dial pad (9 ) for speed dialing. The invention has the advantages of high detection precision, wide range, fast frequency, convenient wearing, light weight and long battery life, and has very broad application prospects.

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...
