Abstract

The invention discloses visually impaired people passage prediction glasses based on an RGB-D camera and stereophonic sound. An infrared projector can project invisible near-infrared static speckles, images are captured through two infrared cameras and an RGB color camera, a small processor processes the acquired images and calculates to obtain depth images, an attitude angle sensor acquires camera attitude angle information, the small processor uses the depth information and the attitude angle information to compute the height image and divides the height image into pieces, the divided depth information is transformed into a stereophonic sound and finally a bone conduction headphone transmits the stereophonic sound to visually impaired people for assistance. The visually impaired people passage prediction glasses can well meet the prediction requirements on visually impaired people passage.

Description

technical field [0001] The invention belongs to the technical fields of assistive technology for visually impaired persons, binocular vision technology, three-dimensional environment perception technology and stereo interaction technology. In particular, it relates to a path prediction glasses for the visually impaired based on an RGB-D camera and stereo sound. The invisible near-infrared static speckle is projected by an infrared projector, and images are collected by two infrared cameras and an RGB camera. The collected image is processed, and the depth image is obtained by calculation. Further use the depth information and attitude angle information to calculate and obtain the height image, and block the height image, convert the depth information obtained by the block into a stereo signal, and finally use the bone conduction earphone to pass it to the visually impaired for assistance. Background technique [0002] According to the World Health Organization, there are 28...
