A blind guide control method and device

Abstract

The invention discloses a blind guide control method and device, belonging to the navigation technical field. The method comprises the following steps: receiving a navigation request, wherein the navigation request carries the identification information of the blind guide device; if it is determined that the obtained current position of the blind guide device is located in any set blind guide area, obtaining the surveillance video stream in the set time period collected by the camera in the blind guide area is obtained; comparing the stored face image of a blind person corresponding to the identification of the blind guide device with a face image extracted from each video frame in the surveillance video stream to obtain a video frame containing the blind person's face image, and determining a position of the blind person in the blind guide region by using the video frame containing the blind person's face image; determining a feature of an obstacle appearing in the set area from the blind person in the blind guide area, and transmitting the feature of the obstacle to the blind guide equipment for broadcasting, so as to meet the travel needs of the blind person as much as possible.

Description

technical field [0001] The present application relates to the technical field of navigation, and in particular, to a method and device for blind guidance control. Background technique [0002] Although my country's economy has grown significantly and technology has made great progress, the living conditions of the blind have not been improved much, especially when going out, the complex real environment has brought great safety to the blind. hidden danger. [0003] In real life, blind people usually use guide dogs or crutches to help them recognize their way when they go out. Using this method is likely to consume a lot of energy and physical strength of the blind, and cannot meet the needs of the blind when going out. SUMMARY OF THE INVENTION [0004] The embodiments of the present application provide a blind guidance control method and device, which can meet the going out requirements of the blind as much as possible. [0005] In a first aspect, a blind guidance control...

Problems solved by technology

[0002] Although my country's economy has grown significantly and technology has made great progress, the living conditions of the blind have not been greatly improved, especially when they go out. The complex real environment has brought great safety to the travel of the blind. Hidden danger

[0003] In real life, when the blind go out, they usually use guide dogs or crutches to help them find their way. Using this method is likely to consume more energy and physical strength of the blind, and cannot meet the needs of the blind to go out.
