Abstract

The invention discloses a map generation method and device, and equipment, and relates to the technical field of intelligent driving, in particular to the technical field of positioning. According tothe technical scheme, the map generation method comprises the steps of obtaining current point cloud data corresponding to at least one region block in a target region, and for any one first region block in the at least one region block, determining position information of each point in the first region block according to the current point cloud data corresponding to the first region block; and generating a map corresponding to the first region block according to the position information of each point in the first region block. Through the above process, the map corresponding to each region block is generated by taking the region block as the granularity. Therefore, the map generation process is localized, and the map generation result is localized, and the whole map can be generated in anincremental or parallel mode instead of being regenerated every time, and computing resources and time resources needed in the drawing process are reduced, and the map generation efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of intelligent driving, and in particular to a method, device and equipment for generating a map. Background technique [0002] Intelligent driving technology needs to rely on high-precision maps. Therefore, the road information in high-precision maps needs to be very accurate to ensure the safe driving of intelligent driving vehicles. [0003] In the prior art, when generating a high-precision map, the map is drawn at the granularity of the entire park corresponding to the map. For example, if you need to make a map of Beijing, you need to input the cartographic data corresponding to all regions in Beijing at one time. The above-mentioned mapping process takes a long time and consumes a lot of computing resources, resulting in low map generation efficiency. Contents of the invention [0004] The present application provides a map generation method, device and equipment to improve map generatio...
