The invention relates to a road condition early warning method and system, and the method comprises the steps: obtaining first position information from at least one first patrol device, and automatically marking the first position information in a road network; after marking of the first position information is completed, a driving road network map is generated; the driving road network map comprises a driving path and first position information; issuing the driving road network map to a driving vehicle; the running vehicle determines a first indication signal and a second indication signal in combination with the first position information; and the running vehicle determines at least one early warning state according to the first indication signal and the second indication signal. According to the invention, through combination of pedestrian crossing position information provided by a navigation positioning system and pedestrian crossing detection based on machine vision, cooperative work of visual detection and position detection is formed, road condition early warning under conditions of severe weather, crowded road conditions, novel pedestrian crossings and the like is realized, and it is ensured that alarm information is correctly and timely sent to vehicle drivers.

    本发明涉及一种路况预警方法及系统,所述方法包括:获取各第一位置信息并在路网中自动标注,所述第一位置信息来自于至少一个第一巡扫装置;完成第一位置信息的标注后,生成行车路网图;所述行车路网图中包括行车路径及第一位置信息;下发所述行车路网图给行驶车辆;所述行驶车辆结合所述第一位置信息,确定第一指示信号和第二指示信号;所述行驶车辆根据所述第一指示信号和所述第二指示信号,确定至少一个预警状态。本发明,通过导航定位系统提供的人行横道位置信息,与基于机器视觉检测人行横道结合,形成视觉检测与位置检测协同工作,实现恶劣天气、拥挤路况、新型人行横道等条件下的路况预警,确保报警信息正确、及时的发送给车辆驾驶人员。
