Embodiments of the invention generally relate to methods and systems for navigating a vehicle. Specifically, a method may include accessing a subset of multiple types of sensor data, aligning the subset of sensor data relative to a global coordinate system based on the multiple types of sensor data to form aligned sensor data, and generating a dataset of three-dimensional map data. The method further includes detecting data changes relative to the at least two data sets of the three-dimensional map data, and applying the data changes to form updated three-dimensional map data. The data change may represent a change in state of the environment in which the sensor data is sensed. A change in state of the environment may be related to the presence or absence of an object located therein.

    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。
