Abstract

The embodiment of the invention discloses a road section division method and device. By applying the scheme provided by the embodiment of the invention, the local special scene can be identified after the road topology is obtained according to the standard map, the target road section boundary is searched from the local special semantic point of the local special scene, and the target road section boundary is a straight road section or a map boundary with relatively high definition, that is to say, the target road section boundary identification degree is high, so that the road division can be accurately completed even if the ground marks are not clear or even disordered, and the road section division precision is improved. Moreover, local special scenes, namely road bifurcations or confluence, are divided into the same road section, so that the road can be prevented from being divided too fragmentarily, and each road section can clearly express the semantics of the road scene.

Description

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