AI navigation glasses for blind people

Abstract

The invention discloses AI (Artificial Intelligence) navigation glasses for blind people. The glasses consist of a glasses frame and a PCBA arranged on the glasses frame. The PCBA is provided with a binocular camera, a six-axis IMU sensor, an embedded AI processor, a voice processor, a Bluetooth / WiFi module and a mobile data transmission module. The binocular camera and the 6-axis IMU sensor collect video images and motion tracks of surroundings, and the AI navigation processor completes environment characteristic recognition, space matching, deep information extraction and three-dimensional reconstruction through a vision algorithm, and helps blind people establish environment three-dimensional perception through voice description of the environment characteristics. The voice description is output to the blind people through the bone conduction earphone, and the blind people wearing the glasses complete navigation and avoid obstacles under the prompt of the voice so as to realize free walking.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to AI navigation glasses for the blind. . Background technique [0002] The robot vision system refers to the use of camera perception and other sensor perception, and the use of AI to realize the human visual function, that is, to realize the recognition of the objective three-dimensional world, especially the detailed perception of the surrounding environment, so that the robot has the ability to feel the environment similar to humans. The current mainstream robot vision systems include monocular vision, binocular stereo vision, multi-eye vision and panoramic vision. The binocular vision system consists of two cameras. It uses the principle of triangulation to obtain the depth information of the scene, and can reconstruct the three-dimensional shape and position of the surrounding scenery. It is similar to the stereoscopic function of the human eye. It is used in robot posi...

AI Technical Summary

Problems solved by technology

Most of the blind navigation systems that have been released are based on ultrasonic recognition systems. The existing ultrasonic blind guide products can only determine whether there are obstacles ahead and the distance of obstacles, and these cannot bring substantial help to the blind.

However, there is a problem of accuracy in GPS global positioning system navigation, which can only provide an approximate location at most, and there is a danger
