Problems solved by technology

[0002] In daily life, blind people basically use ordinary blind sticks to assist walking. The traditional crutches for blind people are just an ordinary long stick. Hidden danger
In the past, guide dogs can help to a certain extent, but guide dogs cannot provide prompts for precise objects or specific obstacle avoidance prompts in the path, and the cost of training is high, the universality is not very good, and it is not suitable for large-scale promotional use of
Moreover, when a blind person needs to find an item, the guide dog cannot bring the blind person to the corresponding position, and the blind person needs to go to each place by himself to find it. It is convenient to pick up the items, usually they will be put back to the original place after using them, but once the items are not put back to the original place, then the blind person may have to grope through multiple places to find the items, which reduces the efficiency of finding the items on the one hand, and on the other hand On the one hand, in the process of searching, as the blind pass through more places, more obstacles will be encountered by the blind during walking, and there will be more potential safety hazards

Embodiment 1

[0023] Basic as attached figure 1 Shown: the CNN-based blind-guiding auxiliary crutch, including a crutch body, the crutch body is provided with an auxiliary system, and the auxiliary system is located in the middle or middle and lower part of the crutch body, in this embodiment, it is located at the middle and lower position.

[0024] The auxiliary system includes a storage module and a picture library storing item information. The item information includes item names and item images; item information includes common item information, obstacle information, and blind road information. In this embodiment, taking common item information as an example, common The item information includes item pictures and item names; in this embodiment, the storage module adopts a 128G SD card.

[0025] The image acquisition module is used to obtain environmental video information; in the present embodiment, the image acquisition module is a camera, and the image acquisition module is installed ...

Embodiment 2

[0048] The difference from Embodiment 1 is that in this embodiment, the item information also includes signal light information, and the signal light information includes signal light images and signal light status;

[0049] The identification module is also used to identify whether there is a signal light in the image frame according to the signal light information. When the signal light is recognized, it also recognizes the state of the signal light. In this embodiment, the state of the signal light includes the vehicle traffic state and the pedestrian traffic state, wherein the vehicle traffic state The red light is on, and the green light is on when the pedestrian is in the traffic state; when the signal light is recognized as the pedestrian traffic state, the voice module sends the traffic prompt information, and also recognizes the pedestrian traffic countdown displayed by the signal light.

[0050] The storage module is pre-stored with a time threshold; it also includes ...

Abstract

The invention relates to the technical field of neural network control systems and computer vision, and provides a CNN-based blind guiding auxiliary walking stick in order to solve the problem that a walking stick in the prior art is single in function. The CNN-based blind guiding auxiliary walking stick comprises a walking stick body and an auxiliary system, wherein the auxiliary system comprises a storage module, an image acquisition module, an input module, a processing module, an identification module, a positioning module and a voice module; the storage module is used for storing a picture library of article information; the image acquisition module is used for acquiring environment video information; the input module is used for acquiring searching information; the processing module is used for processing the environment video information to obtain an image frame and processing the searching information to obtain a searching target; the identification module is loaded with a CNN model-based identification model and is used for identifying the image frame and marking an identified actual target; the positioning module is used for positioning the marked actual target to obtain a target position and positioning a current position, and performing path planning according to the current position and the target position to obtain a walking path; and the voice module is used for playing the walking path.

Description

technical field [0001] The invention relates to the technical fields of neural network control systems and computer vision, in particular to a CNN-based blind-guiding auxiliary crutch. Background technique [0002] In daily life, blind people basically use ordinary blind sticks to assist walking. The traditional crutches for blind people are just an ordinary long stick. Hidden danger.
