CNN-based blind guiding auxiliary walking stick

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. 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. 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, bu...

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
