Abstract

The invention relates to a method and a device for constructing a road intersection road network, a storage medium and electronic equipment. The method comprises the steps of acquiring lane line information of a road connected with an intersection and pointing information of a guiding arrow, close to the intersection, of the road; for each road, determining the connection relation between the roadand the intersection according to the pointing information of the guiding arrows of the road, and the connection relation is used for representing whether the road is a driving-in road or a driving-out road of the intersection; and determining a pairing relationship between a lane in the entry road of the intersection and a lane in the exit road of the intersection according to the lane line information and the pointing information of the guide arrows in each entry road and the lane line information and the pointing information of the guide arrows in each exit road. By means of the method andthe device, automatic construction of the road intersection road network can be achieved, and efficiency and accuracy are high.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a method, device, storage medium and electronic equipment for constructing a road intersection network. Background technique [0002] High-precision maps refer to high-precision, finely defined maps. Compared with ordinary maps, they contain richer information, such as road network data, road intersection road network data, etc., and become autonomous driving / unmanned driving. An important part of technology. [0003] The original data sources of high-precision maps are point cloud data and panoramas collected by professional collection vehicles. When constructing the road network of high-precision maps, through a series of processing such as cleaning, vector extraction, and data processing of the original data, vector data such as solid lines, dashed lines, and outlines of guiding arrows in the road surface are obtained, and these roads are further analyzed. Th...
