A blind guiding system based on online interaction and scene recognition

By using an online interactive and scene recognition-based navigation system, combined with glasses cameras, wireless headphones, and white canes with buttons, the system utilizes satellite positioning navigation and electronic maps to plan routes and obtains real-time scene and direction information when lost. This solves the navigation difficulties faced by visually impaired people in complex scenarios and achieves more efficient navigation guidance.

AI Technical Summary

Technical Problem

Existing intelligent guidance systems for the blind cannot effectively reconstruct the sense of direction of visually impaired people in complex scenarios, and frequent prompts interfere with their judgment of the current scene.

Method used

The system employs an online interactive and scene recognition-based navigation system, combining glasses with a camera, wireless headphones, a white cane with buttons, and a smartphone. It uses satellite positioning for navigation and electronic maps to plan routes. When lost, users can obtain real-time scene and direction information through buttons or online interaction, and the system provides voice and vibration prompts through the backend system.

Benefits of technology

It enhances the sense of direction for visually impaired people while moving, helps them walk more easily on planned routes, and enables navigation guidance in complex scenarios.

Abstract

The application provides a blind guiding system based on online interaction and scene recognition, divides a route into path points and path lines, takes an entry point of a path line as a navigation focus, realizes scene information through a camera arranged on glasses, detects a current scene through software, interacts with local software through a button arranged on a blind stick when needed, can interact with a background system located at a remote end when facing a complex scene, includes checking real-time video shot by a camera of a user, so that more effective detection and judgment are obtained, although the application needs background calculation support in a use process, is only an enhanced and auxiliary means, and can also complete walking navigation in an offline mode, and has the advantages of simple structure and convenient use.
