A traffic light recognition device for visually impaired people relates to the field of image recognition. The invention aims to overcome the defect that the passing of visually impaired people generally depends on seeing-eye dogs at present. The system solves the problems that the blind guide dogs are not high in universality, visually impaired people are easily guided to violate traffic rules, and personal safety risks are caused, and comprises an image acquisition unit, a processing unit and a voice prompt unit; the image acquisition unit is used for acquiring a real-time signal lamp image of the traffic signal lamp; the processing unit is used for identifying a lightening sign of the traffic signal lamp according to the real-time signal lamp image; comparing the lightening mark with a pre-stored passing mark, and generating a passable broadcast signal when the lightening mark is matched with the passing mark; the lightening marks comprise a red light, a green light and a yellow light; the passing sign comprises a green light; and the voice prompt unit is used for broadcasting a pre-configured passable voice according to the passable broadcast signal.
视障人士交通信号灯识别装置,涉及一种图像识别领域。目的是为了克服现在视障人士通行一般依赖于导盲犬。而导盲犬普适性不高,并且容易引导视障人士违反交通规则,带来人身安全风险的问题,包括图像采集单元、处理单元和语音提示单元;图像采集单元,用于采集交通信号灯的实时信号灯图像;处理单元,用于根据实时信号灯图像识别出交通信号灯的点亮标志;并将点亮标志与预存储的通行标志对比,在点亮标志与通行标志匹配时,生成可通行播报信号;点亮标志包括红灯、绿灯和黄灯;通行标志包括绿灯;语音提示单元,用于根据可通行播报信号播报预先配置的可通行语音。
