Abstract

The embodiment of the invention discloses a method and device for dividing road sections. Applying the solution provided by the embodiment of the present invention, after obtaining the road topology according to the standard map, the local special scene can be identified, and the target road segment boundary can be found from the local special semantic point of the local special scene. High straight line sections or map boundaries, that is to say, the boundary of the target road section has a high degree of recognition, so that even when the ground signs are unclear or even chaotic, the road division can be accurately completed and the accuracy of road section division can be improved. Moreover, dividing local special scenes, that is, road bifurcations or junctions into the same road segment can avoid dividing the roads too fragmentarily, so that each road segment can clearly express the semantics of the road scene.

Description

technical field [0001] The present invention relates to the technical field of map construction, and in particular, to a road segment division method and device. Background technique [0002] The high-precision map is a global continuous large map. Before use, the entire map needs to be divided into road segments one by one. When using it, several road segments within a certain range can be dynamically loaded according to the current positioning to reduce device memory and computing consumption. . [0003] The known high-precision map road segment division method is mainly to segment according to the shape of the lane line at the change of the lane number or the road bifurcation and junction, so that the number of lanes in the segmented road segment is fixed. However, in the above road segment division method, when the lane lines are unclear or even missing, it is difficult to accurately divide the road segment, that is, the road segment division accuracy is low. Therefore...
