Problems solved by technology

[0003] Traditional blind guide equipment, that is, wooden or iron crutches, is difficult to provide enough information feedback to the blind in the current environment, causing the blind to not move in time and adding a lot of inconvenience
With the advancement of science and technology, guide glasses, an advanced blind-guiding device, have been produced, which have good recognition for non-transparent objects, but with the application of translucent or nearly transparent objects, blind-guiding devices based solely on image cameras Glasses are difficult to meet the requirements

Embodiment 1

[0046] Provided according to the present invention is a vision-assistance system for the blind cane and mirror with mixed visual-tactile information, such as figure 1 shown, including:

[0047] Module M1: use the visual auxiliary glasses body to obtain the visual information of real-time perception of the environment;

[0048] Module M2: Use the guide stick body to obtain the tactile and kinesthetic information of environmental perception;

[0049] Module M3: Integrate the tactile and kinesthetic information of environmental perception with the visual information of real-time perception of the environment, and use the trained neural network to make real-time judgments on the integrated information, identify the real-time position of external environmental objects, and The result of the judgment is transmitted to the wearer, so as to realize the path guidance for the blind.

[0050] Specifically, the visual aid glasses include an image camera, and the image camera is used to ...

Embodiment 2

[0081] Embodiment 2 is a preferred example of Embodiment 1

[0082] According to the present invention, a combination of visual guide glasses and a guide stick for the blind, comprising:

[0083] Vision aid glasses body: the glasses include a back-end power supply part for providing power and reducing the force on the wearer's nose bridge and a front-end part for carrying an image camera and various controllers; wherein, the back-end power supply part mainly adopts the volume It is composed of small, large-capacity and soft batteries, which are mainly used to provide the power required by the glasses, use the force of the human neck, and reduce the force of the wearer's nose bridge.

[0084] Guide cane body: The guide cane includes an ultrasonic detector module for kinesthetic detection, a power supply module, a main controller and a wireless module. The wireless module is used for information interaction between guide glasses and guide sticks.

[0085] Integrated control sy...

Abstract

The invention provides a blind guiding crutch mirror visual aid system and method for mixing visual sense and visual sense information. The blind guiding crutch mirror visual aid system comprises a module M1, a module M2 and a module M3, wherein the module M1 obtains visual information perceived in real time by the environment through a visual aid glasses body; the module M2 is used for acquiring touch and kinesthetic information perceived by the environment by utilizing the blind guiding stick body; the module M3 is used for integrating the touch and kinesthetic information perceived by the environment and the visual information perceived by the environment in real time, identifying the real-time position of an external environment object, judging by using a neural network model based on the real-time position of the environment object, and transmitting a judgment result to a wearer, so as to realize path guide for the blind.

Description

technical field [0001] The present invention relates to the field of daily life of blind people, in particular, to a vision-aiding system and method for a blind cane and mirror with mixed visual tactile information, and more particularly, to a mixed visual tactile information for assisting blind people to act in daily life guide cane and mirror vision aids. Background technique [0002] The eye is an extension of the brain function. The eye's unique fine visual sensitivity is an indispensable visual organ for human beings and plays a very important role in our daily life. In our real life, there are still many visually impaired people in our country. Most of them have completely lost their vision ability, whether it is caused by congenital physical insufficiency or some acquired accidents, and they completely lose their vision. Abilities have formed a huge obstacle to their daily life. With the development of modern society, the construction of more and more roads, and the...
