The invention provides a road backlighting condition real-time evaluation and early warning method, system and device based on weather information and a storage medium, and belongs to the technical field of driving safety early warning. The method comprises the following steps: acquiring regional weather information of a driving road section; judging whether the weather type of the driving road section is a weather type with sufficient illumination according to the weather information; if yes, judging whether the cloud layer of the driving road section meets a preset condition or not according to the weather information; if yes, calculating the illumination direction at the current moment based on the latitude and longitude coordinates on the map; road matching is carried out based on the illumination direction and the road orientation of the open source map, and whether backlight driving exists on the road is judged; if yes, early warning marking is conducted on the backlight coordinate points on the map, and real-time displaying and updating are conducted. According to the invention, the accuracy and real-time performance of backlight early warning are improved, and the road driving safety can be improved.
本发明提供一种基于天气信息的路段逆光情况实时评估预警方法、系统、设备以及存储介质,属于行车安全预警技术领域。该方法包括:获取行驶路段区域气象信息;根据气象信息判断行驶路段天气类型是否为光照充足的天气类型;若是,则根据气象信息判断行驶路段的云层是否满足预设条件;若满足,则基于地图上的经纬度坐标,计算当前时刻的光照方向;基于光照方向以及开源地图的道路方位进行道路匹配,判断道路是否存在逆光行驶;若存在,则在地图上对逆光坐标点进行预警标注并实时显示更新。本发明提高了逆光预警的准确性和实时性,有助于提升道路行车安全。
