The invention discloses a traffic light intersection blind guiding method and blind guiding device based on machine vision, and the blind guiding method comprises the steps: collecting the environment image and zebra crossing image information of a traffic light intersection, extracting the color of a traffic light and countdown information, judging whether the traffic light can pass through the intersection, extracting the zebra crossing information, and judging whether a user deviates from a correct route or not, and prompting the user whether it is suitable to pass the intersection. The blind guiding device comprises a mirror frame, and a power supply module, a central processing module, a voice broadcast module, an image acquisition module and a wireless communication module which are arranged on the mirror frame; the device can provide accurate guidance for the blind needing to pass through the traffic light intersection, guarantees the personal safety of the blind in daily traffic, and is high in reliability and precision, simple in structure and convenient to carry.

    本发明公开了基于机器视觉的红绿灯路口导盲方法及导盲装置,导盲方法通过采集待经过红绿灯路口的环境图像和斑马线图像信息,提取信号灯颜色和倒计时信息判断是否可以通过路口,提取斑马线信息判定用户是否偏离正确路线,并提示用户是否适合通过路口,导盲装置包括镜框和设于镜框上的电源模块、中央处理模块、语音播报模块、图像采集模块和无线通讯模块;本发明能够为需要通过红绿灯路口的盲人提供准确指引,保障盲人在日常交通中的人身安全,可靠度高,精确度高,且结构简单,携带方便。
