The invention discloses a multifunctional intelligent blind guiding walking stick based on machine vision. The multifunctional intelligent blind guiding walking stick comprises a walking stick body; a first ultrasonic module, a second ultrasonic module, a third ultrasonic module, a camera module, a voice broadcast module and a processor are arranged on the walking stick body; the first ultrasonic module, the second ultrasonic module and the third ultrasonic module are respectively used for detecting distances from obstacles in front, left and right of the walking stick to the walking stick; the camera module is used for collecting environment images in real time; the processor is used for inputting the environment images collected by the camera module into a traffic light recognition model and outputting a traffic light recognition result; the processor is also used for comparing the distance between the obstacle and the walking stick with a preset safety distance to obtain an obstacle avoidance result; and the processor is also used for controlling the voice broadcast module to carry out voice navigation reminding according to the traffic light recognition result and the obstacle avoidance result. According to the invention, the safety in the aspect of a blind guiding function is greatly improved; the blind can be guided to safely carry out social activities; and the safety of the blind is maintained.

    本发明公开了一种基于机器视觉的多功能智能导盲手杖,包括手杖本体,手杖本体上设置有第一超声波模块、第二超声波模块、第三超声波模块、摄像头模块、语音播报模块和处理器,第一超声波模块、第二超声波模块和第三超声波模块分别用于探测手杖前方、左方和右方障碍物距离手杖的距离;摄像头模块用于实时采集环境图像;处理器用于将摄像头模块采集的环境图像输入红绿灯识别模型中,输出红绿灯识别结果;还用于将障碍物距离手杖的距离与预设安全距离进行比较,得到避障结果;还用于根据红绿灯识别结果以及避障结果控制语音播报模块进行语音导航提醒。本发明在导盲功能方面的安全性有了极大的提升,能够引导盲人安全的进行社会活动,维护盲人的安全。
