Abstract

The invention discloses a pair of RGB-D-camera-and-stereo-based obstacle early-warning glasses for visual impaired people. According to the pair of glasses, an infrared projector is used for projecting visible near-infrared static speckle; two infrared cameras and one RGB camera are used for collecting images; a micro processor processed the collected images, calculation is carried out to obtain a depth image and block division is carried out on the depth image, depth information obtained by block division is converted into a stereo signal; and then a bone conduction earphone is used for transmitting the stereo signal to a visual impaired user for assisting. Therefore, a requirement of obstacle early warning of visual impaired people can be met well.

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. The invention includes a kind of obstacle warning glasses for visually impaired persons based on RGB-D camera and stereo sound, and relates to a method of projecting invisible near-infrared static speckles by using an infrared projector, and collecting images by using two infrared cameras and one RGB camera , the small processor processes the collected image, obtains the depth image, and divides the depth image into blocks, and finally converts the block depth information into a stereo signal, and finally uses the bone conduction earphone to pass it to the visually impaired for assistance. Object warning glasses. Background technique [0002] According to the World Health Organization, there are 285 million visually impaired people worldw...
