本发明的实施例总体上涉及用于为车辆导航的方法和系统。具体而言,一种方法可以包括访问多种类型传感器数据的子集,基于多种类型的传感器数据相对于全球坐标系对准传感器数据的子集以形成对准传感器数据,以及产生三维地图数据的数据集。该方法还包括检测相对于三维地图数据的至少两个数据集的数据变化,以及应用数据的变化以形成更新的三维地图数据。数据变化可以代表感测传感器数据的环境的状态变化。环境的状态变化可以与位于其中的对象的存在或不存在相关。

    Various embodiments relate generally to autonomous vehicles and associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to provide map data for autonomous vehicles. In particular, a method may include accessing subsets of multiple types of sensor data, aligning subsets of sensor data relative to a global coordinate system based on the multiple types of sensor data to form aligned sensor data, and generating datasets of three-dimensional map data. The method further includes detecting a change in data relative to at least two datasets of the three-dimensional map data and applying the change in data to form updated three-dimensional map data. The change in data may be representative of a state change of an environment at which the sensor data is sensed. The state change of the environment may be related to the presence or absences of an object located therein.
