The invention discloses an auxiliary driving method and system for intersection green light reminding. The method comprises the following steps: acquiring image data; analyzing the image, and determining the current lane and traffic light information; if yes, determining the color of the traffic light; if the color of the traffic light is green, judging the shape of a green light, and if the green light is round or arrow-shaped and the shape is matched with the lane information, detecting the current speed of the vehicle; if the distance is larger than or equal to the set value, detecting the current speed of the vehicle after first response time; and if the current speed of the vehicle is equal to zero, generating prompt information. The system comprises an image acquisition module, an information processing and control module, a distance acquisition module, a speed acquisition module and a prompt module. According to the method, drivers who do not know that the signal lamps at the intersection turn green can be helped to quickly adjust the driving state, so that backlog of rear vehicles can be effectively avoided, and the traffic pressure of urban roads is relieved to a certain extent.
本发明公开了一种用于路口绿灯提醒的辅助驾驶方法和系统。该方法包括:采集图像数据;分析图像,确定当前车道和红绿灯信息;若存在红绿灯,确定红绿灯的颜色;若红绿灯颜色为绿色,判断绿灯形状,若绿灯为圆形或绿灯为箭头形且该形状与车道信息匹配时,检测车辆当前速度;若距离大于等于设定值,等待第一反应时间后,检测车辆当前速度;若车辆当前速度等于零,生成提示信息。该系统包括:图像采集模块、信息处理与控制模块、距离采集模块、速度采集模块和提示模块。本发明可以帮助未意识到路口信号灯已变绿的驾驶人员快速调整驾驶状态,从而可以有效避免后方车辆积压,在一定程度上缓解城市道路交通压力。
