Novel wearable blind guiding equipment and working method thereof

Abstract

The invention discloses novel wearable blind guiding equipment and a working method thereof. The novel wearable blind guiding equipment is combined with tactile sticks for use and is used for assisting the blind to go out safely. The blind guiding equipment can automatically monitor the using environment, prompt users to switch working modes and provide corresponding guiding messages. The system closes a redundancy function module according to the working modes automatically, energy consumption is lowered, and the working time of the equipment is prolonged. Contact combinations are used for expressing complex blind guiding signals, and thus the privacy is better. The novel wearable blind guiding equipment includes but is not limited to a CPU, an input module, a speech recognition module, an image processing module, an output module, a communication module, a power module and a function device integration carrier. The working modes of the blind guiding equipment include but are not limited to the sidewalk mode, the traffic light intersection mode and the free mode. The sidewalk mode guides the blind to evade front obstacles in a ranging manner, the traffic light intersection mode acquires traffic light information in an image processing manner and guides the blind to achieve safety passage, and the free mode judges the condition of the surrounding environment by comprehensively utilizing the ranging information and the image processing information and guides the blind to move forward safely.

Description

technical field [0001] The invention relates to a novel wearable blind-guiding device and a working method thereof. The blind guide device can automatically monitor the use environment, prompt the user to switch the working mode, and provide corresponding guidance information; the system automatically closes the redundant function modules according to the working mode, reduces energy consumption, and prolongs the working time of the equipment; through the combination of contacts, complex Guided blind signal, better privacy. Background technique [0002] Blind people are a vulnerable group in society, and it is difficult for them to travel alone, and their range of activities is limited. At present, the blind travel mainly rely on the help of blind sticks and guide dogs. Guide dogs require long hours of training, are expensive and troublesome to keep. Although the blind cane is easy to use and low in price, its detection range is small and it is difficult to detect obstacl...

Problems solved by technology

Guide dogs require long hours of training, are expensive and troublesome to keep

Although the blind cane is easy to use and low in price, its detection range is small and it is difficult to detect obstacles above the chest in time

In addition, compared with simple environments such as blind roads and sidewalks, it is more difficult and dangerous for blind people to travel with only blind sticks at traffic light intersections, mixed road sections with pedestrians and vehicles, and environments without traffic signs.

[0003] At present, there have been many technical inventions about blind guide devices, but either the functions are too simple and the practicability is very limited, or the energy consumption is too large to last for a long time, so there are still no mature blind guide devices on the market.
