Abstract

The invention relates to a road element identification and road network construction method and device, a storage medium and an electronic device, and the road network construction method comprises the steps: obtaining the feature information of each road element which comprises a lane line and a guide arrow; according to the relative position relationship between the guide arrow and the lane line, establishing an association relationship between the guide arrow and the lane line; clustering the acquired lane lines according to the position information of each lane line and the pointing information of the guide arrow associated with each lane line to obtain a plurality of groups of lane lines; and according to the position information of the lane line in each road and the position information of other road elements except the lane line and the guide arrow, establishing an association relationship between the other road elements and the road. By means of the technical scheme, automaticconstruction of the road network with strong semantic information can be achieved, manual participation is not needed in the whole process, and efficiency and accuracy are higher.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a road element identification and road network construction method, device, storage medium and electronic equipment. 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 a road network of a high-precision map, through a series of processing such as cleaning, vector extraction, and data processing of the original data, vector data such as points, solid lines, dashed lines, and contour lines in the road surface are obtained. However, these vector data It is ...
