The invention provides a navigation information offline prompting method, a server and a storage medium. The method comprises the following steps: acquiring traffic signs on a road; obtaining a target driving path of the vehicle according to the traffic sign on the road; acquiring driving path information of the vehicle in the driving process of the vehicle along the target driving path; judging the road type of vehicle driving according to the driving path information of the vehicle; and modifying and prompting the navigation information according to the road type. According to the method for detecting whether the vehicle passes the specific type of road according to the movement track measured by the vehicle, the navigation information is modified after the vehicle passes the specific type of road, so that the display accuracy of the traffic sign recognition function in an off-line state (namely when electronic map data cannot be obtained) can be greatly improved, and the traffic sign recognition effect is improved. Therefore, the effect of preventing accidents is achieved.
本发明提供了一种导航信息离线提示方法、服务器及存储介质。其中方法包括如下步骤:获取道路上的交通标志;根据所述道路上的交通标志,获取车辆的目标行驶路径;在车辆沿着所述目标行驶路径的行驶过程中获取车辆的行驶路径信息;根据所述车辆的行驶路径信息判断车辆行驶的道路类型;根据所述道路类型对导航信息进行修改并提示。本发明提中依靠自车测量的运动轨迹来检测车辆是否驶过特定类型道路的方法,在驶过特定类型道路后,修改导航信息,可以大大提高在离线状态下(也即无法获取电子地图数据时)交通标志识别功能显示的准确性,从而起到预防事故的发生的作用。
