Intelligent system for blind person travel guidance and method thereof

Abstract

The invention discloses an intelligent system for blind person travel guidance and a method thereof, and the system comprises a mobile terminal, portable radar equipment, and AI glasses, and the blindperson plans a travel route through the voice of the mobile terminal, detects the surrounding objects of the blind person at 360 degrees through a millimeter-wave radar worn at the waist of the blindperson, and obtains the radar ranging data; the shape and the size of the obstacle by combining an AI glasses visual imaging method can be analyzed to obtain image data; and radar ranging data and image data are received in real time to obtain obstacle avoidance information, and a voice navigation instruction is sent in combination with the planned travel route. The millimeter-wave radar and theAI vision are comprehensively utilized for rapid judgment, the advantages of the millimeter-wave radar and the AI vision are brought into full play, a more accurate guidance direction is provided forthe blind person, and the blind person finally reaches the destination.

Description

technical field [0001] The invention relates to the technical field of travel aids for the blind, in particular to an intelligent system and method for travel guidance for the blind. Background technique [0002] In the eyes of the blind, the whole world is close at hand, but out of reach, because they cannot see all kinds of objects around them. Blind people cannot directly observe the surrounding environment due to lack of vision, and it is often very inconvenient and dangerous to travel. Blind people must rely on guide dogs or guiding infrastructure auxiliary equipment for outdoor activities. Due to physical defects, blind people have many inconveniences in life and work. How to ensure the travel safety of blind people is a problem that the whole society needs to solve. [0003] Ordinary guide dogs and guide sticks have a limited range of exploration, and blind people need to continue to manually control the guide sticks to explore. There are also many current guiding de...

AI Technical Summary

Problems solved by technology

However, the guidance based on ultrasound can only inform blind people about the distance of obstacles in front of them, which has great limitations.

There are also some methods of using camera imaging to analyze the shape and size of obstacles, and then transmit them to users through tactile and audio. Although this is a great improvement compared to pure ultrasound, it still cannot be accurately transmitted to blind users, because Vision algorithms alone cannot completely solve the travel problems of the blind and visually impaired. A single vision algorithm cannot achieve the goal of blind people traveling independently in terms of recognition rate and distance calculation.
