Problems solved by technology

There are many kinds of auxiliary walking devices that can guide the blind, but in the past, there are still many dead spaces in the process of assisting the blind to walk, and the existing blind guiding devices also assist the blind to a certain extent It brings certain additional obstacles to the blind, so it cannot meet the needs of convenient walking brought about by the accelerated pace of life, which will greatly limit the scope of life of the blind, and then greatly affect the quality of life of the blind

Abstract

The invention relates to the technical field of blind guide devices, and specifically relates to a 3D blind guiding device and a method based on a TOF technology. The blind guiding device comprises a3D blind guide device body. The 3D blind guiding device is provided with a sensing module, which comprises a ToF sensor and a MEMS inertial sensor. The ToF sensor is used for detecting the distance from the human body to the nearest obstacle and generating the obstacle distance signal, and the MEMS inertial sensor is used for detecting the human body posture and generating the human body posture signal. The signal processing module is used for processing the obstacle distance signal and the human posture signal to obtain the real-time position data of the human body, and can generate the guideinformation according to the real-time position data of the human body. A voice reminder module, which is used for broadcasting the guide information; And a power supply module for supplying power tothe sensing module, the signal processing module and the voice reminder module. The method is implemented based on the device. The device can better provide blind guide service for users.

Description

technical field [0001] The present invention relates to the technical field of blind guide equipment, in particular to a 3D blind guide device and method based on TOF technology. Background technique [0002] Blind people are a vulnerable group in society, and travel is their biggest obstacle to mobility. There are many kinds of auxiliary walking devices that can guide the blind, but in the past, there are still many dead spaces in the process of assisting the blind to walk, and the existing blind guiding devices also assist the blind to a certain extent It brings certain additional obstacles to the blind, so it cannot meet the needs of convenient walking brought about by the accelerated pace of life, which will greatly limit the scope of life of the blind, and then greatly affect the quality of life of the blind. Contents of the invention [0003] The content of the present invention is to provide a 3D blind guide device based on TOF technology, which can overcome some o...
