Sparse map for autonomous vehicle navigation

Systems and methods are provided for constructing, using, and updating sparse maps for autonomous vehicle navigation. In one embodiment, there is provided a navigation system for providing a map to an autonomous vehicle, the system comprising: a processor; and a memory device including instructions that, when executed by a processor, cause the processor to maintain a map including a target trajectory of the autonomous vehicle, the target trajectory including a three-dimensional spline representing a path of travel of the autonomous vehicle, wherein the driving path is constructed by a plurality of driving paths from other autonomous vehicles; determining the presence of a non-transitory condition that does not coincide with the target trajectory of the map based on an analysis of image data from a camera integrated with the autonomous vehicle; and updating the map. 提供了系统和方法以用于构建、使用、和更新用于自主车辆导航的稀疏地图。在一个实施方式中，提供了一种用于向自主车辆提供地图的导航系统，所述系统包括：处理器；和包括指令的存储器设备，当由处理器执行时，所述指令使得所述处理器执行以下操作：维护包括所述自主车辆的目标轨迹的地图，所述目标轨迹包括表示所述
