Intelligent blind guidance terminal for typical intersections

Abstract

The invention relates to an intelligent blind guidance terminal for typical intersections. An image acquisition system includes a camera and a raspberry Pi controller connected to the camera; a smartphone carries an object recognition model and a voice prompting module; the image acquisition system is arranged on hat-type headwear equipment; the raspberry Pi controller is connected to the smart phone; the camera collects images of a current typical intersection and having preset pixels; the raspberry Pi controller sends the images to the smart phone; and the object recognition model performsrecognition on the images and calls the voice prompting module according to recognition results, so that the voice prompting module can play corresponding preset prompting voice. The object recognition model can perform high-efficiency and high-accuracy recognition on the images collected by the camera and call the voice prompting module to play the corresponding preset prompting voice after recognition, so that traffic light situations can be prompted to blind people; and the terminal has advantages of being strong in practicality and low in cost, so that demands of the blind people for safely passing the intersections can be met.

Description

technical field [0001] The invention relates to the technical field of intelligent blind guidance, in particular to an intelligent terminal for blind guidance used at typical crossroads. Background technique [0002] The blind are a special social group that needs more attention from people. How to ensure the safe travel of the blind is the goal that people have been working hard for. Although the existing pedestrian crossings are equipped with guiding facilities mainly for the blind, due to the problems of irregular construction, obstacles, and incompleteness of the blind crossing, the guiding effect of the blind crossing is poor, and the safe travel of the blind cannot be guaranteed. With the continuous advancement of science and technology, smart devices and terminals are becoming more and more mature, and smart blind guide devices are gradually appearing in people's field of vision. [0003] Angel Eye smart glasses are high-tech intelligent guide glasses, which are gene...
