Problems solved by technology

[0004] However, the above-mentioned blind guide device is detected by ultrasonic waves, which can only detect short-distance obstacles, and it is difficult to realize real-time analysis of complex road conditions that change in real time, and fails to detect obstacles, potholes, pedestrians, vehicles, traffic lights, etc. on the walking route. Make accurate detection and reasonable evaluation; and only determine the travel plan based on the current location information and destination information, fail to carry out accurate path planning for the blind walking route according to the specific road conditions, and thus cannot reasonably provide the preferred travel mode, for its travel inconvenience

Embodiment 1

[0029] Embodiment 1, this embodiment proposes an intelligent blind guide device, refer to figure 1 The structural principle diagram of the intelligent blind guide device, including a central processing unit and a positioning module connected to the central processing unit, a voice interaction module, a data storage unit and an image acquisition module; the voice interaction module includes a voice input module and a voice prompt module, for In order to realize the input of destination information and the output of road condition prompt information;

[0030] The data storage unit is used to store user information and map data information;

[0031] The image collection module is used to collect real-time road condition images;

[0032] The central processing unit includes a path planning module and a road condition analysis module; the road condition analysis module includes a traffic signal light detection and analysis module, an image background model building module, a road ...

Embodiment 2

[0044] Embodiment 2, this embodiment proposes a kind of blind guide stick, such as figure 2 As shown, it includes a handle 1 and a guide rod 2 connected with the handle 1. The intelligent blind guide device 3 described in Embodiment 1 is provided on the guide stick, and the function keys are all in Braille, which is convenient for operation. It can be seen that it is convenient for the user to freely select the guide function, and only necessary buttons are set, making the operation easier. Position the user through GPS, input the destination according to the user's voice, and combine the map information to plan the route, and navigate the user's walking through voice. Provide reminders to users. In this embodiment, the blind guide device can also be arranged on hats, backpacks and other alternative daily necessities, which will not be described in detail here.

[0045] To sum up, the intelligent blind guiding device and the blind guiding stick equipped with the device prop...

Abstract

The invention relates to an intelligent blind guiding device and a blind guiding crutch provided with the same. A central processing unit obtains a user location according to a positioning module, obtains destination information through a voice input module, then determines an optimal walking trip route through a path planning module, and plays navigation information through a voice prompt module; and road condition information is analyzed in real time during navigation with the combination of a data storage unit, an image acquisition module and road condition analysis module, and prompt information is played in real time through the voice prompt module to guide a user to travel. The intelligent blind guiding device is integrally arranged on the blind guiding crutch, hats and other articles for daily use, thereby being able to make accurate detection and reasonable evaluation of traffic signals, obstacles, potholes, pedestrians, vehicles and the like, provide timely and reasonable voice prompts for the user, provide convenience for travels of special population fields especially for the blind and the elderly, and achieve precise positioning, path navigation, traffic detection and voice prompt functions, so that the intelligent blind guiding device has a wide popularization significance.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to an intelligent blind-guiding device suitable for the blind or elderly and a blind-guiding stick equipped with the device. Background technique [0002] There are many difficulties in people's life, especially in some special groups of people, such as the blind and the elderly in walking guidance. At present, blind people mainly rely on the help of guide sticks and guide dogs for travel. Guide dogs need long-term training, are expensive, and are troublesome to raise. Although guide sticks are easy to use and low in price, their detection range is small; In addition, it is more difficult and dangerous for blind people to travel only with guide sticks at traffic light intersections, mixed road sections with people and vehicles, and environments without traffic signs. [0003] With the continuous advancement of technology, more and more smart electronic devices...
