Abstract

The invention relates to the technical field of unmanned driving, and mainly provides a target map acquisition method and device, electronic equipment and a readable storage medium, and the method comprises the steps: obtaining a dotting map and information corresponding to each node in the dotting map, and obtaining key points in the dotting map according to the information corresponding to each node in the dotting map, the method comprises the following steps: acquiring a plurality of key points, acquiring target road sections by using a key point sequence formed by the key points, searching nodes simultaneously belonging to a plurality of target road sections according to a road section sequence formed by the target road sections, recording the target road sections corresponding to the nodes, and constructing forks based on the target road sections corresponding to the nodes, and finally, outputting a target map according to the road section sequence and the fork sequence. According to the method, the existing dotting map is converted into the target map, the mapping period is shortened, mapping is carried out according to the key points in the dotting map, the range of the map is reduced, and therefore the utilization rate of the map is increased.

Description

【Technical field】 [0001] The present invention relates to the technical field of unmanned driving, in particular to a target map acquisition method, device, electronic equipment and readable storage medium. 【Background technique】 [0002] Path planning is an important part of unmanned driving. Its task is to find a drivable and safe path from the starting point to the ending point. When performing path planning, it is necessary to represent the road information of the current environment in advance, so that the path planning program of the vehicle knows how to go in the current environment. [0003] For unmanned vehicles, in the prior art, detailed path information is planned through discrete high-precision maps, but the discrete high-precision maps are too large, the construction cycle is long, and the quality requirements for mappers are high, and Unmanned vehicles do not need to use so much environmental information when performing tasks. They only need to know how to wa...
