Blind guiding system and method

Abstract

The embodiment of the invention provides a blind guiding system and method, the system comprises a handheld device and a wearable device, and the handheld device is provided with a button module used for sending an interaction instruction to the wearable device; the wearable device comprises a camera module, a wireless communication module, a processor and a voice broadcast module; the camera module is used for collecting real-time information of surrounding objects; the wireless communication module is used for receiving the interaction instruction sent by the handheld device; the processor is used for analyzing and processing the real-time information and the interaction instruction to obtain blind guiding suggestion information and sending the blind guiding suggestion information to the voice broadcast module; and the voice broadcast module is used for receiving and broadcasting the blind guiding suggestion information. According to the blind guiding system and method provided by the embodiment of the invention, the blind guiding suggestion based on the surrounding real-time information can be provided according to the interaction command of the user.

Description

technical field [0001] The present application belongs to the blind guidance technology, and in particular relates to a blind guidance system and method. Background technique [0002] For people with visual impairments, the travel problem has always been their biggest problem. In order to facilitate the travel of users, there are blind lanes on urban roads. Users rely on the touch of their feet to determine the walking route. When the cane is used to detect obstacles, it is obvious that the environmental information that can be fed back by the pathfinder cane is limited, and bumps occur from time to time, which may endanger life in serious cases. [0003] Among the existing guide-for-blind programs, guide dogs are mainly used to assist travel, and there are also some guide canes based on modern information technology. It is difficult to cover a large area of ​​user groups through guide dog-assisted travel. Guide canes for the blind can realize the user's outdoor guided wal...

Problems solved by technology

[0002] For people with visual impairments, the problem of travel has always been their biggest problem. In order to facilitate the travel of users, blind roads are set up on urban roads, and users rely on the touch of their feet to determine the walking route. The cane is used to detect obstacles. It is obvious that the environmental information that can be fed back by the cane is limited, and collisions occur from time to time, which may be life-threatening in severe cases.

It is difficult to cover a large area of ​​user groups through guide dog assisted travel

The guide cane is used to realize the user's outdoor guide walking, which is based on the location information of satellite positioning and road condition information for navigation, but the actual road conditions are more complicated, and users may encounter road conditions that are not sure whether they can pass. Technical solutions cannot provide guidance suggestions based on user interaction needs
