Map processing method and device

The invention discloses a map processing method and device. The method comprises the following steps: acquiring a target point cloud set and a historical map file of a target road; performing planar projection on the target point cloud set to generate a planar projection drawing; and correcting the historical map file based on the plane projection drawing to obtain a target map file of the target road. According to the invention, the technical problem of low map updating efficiency in the prior art is solved. 本发明公开了一种地图的处理方法、装置。其中，该方法包括：获取目标道路的目标点云集合和历史地图文件；对目标点云集合进行平面投影，生成平面投影图；基于平面投影图对历史地图文件进行修正，得到目标道路的目标地图文件。本发明解决了相关技术中地图的更新效率较慢的技术问题。
