Electronic map road hitching method and equipment

Abstract

The invention provides an electronic map road hitching method and equipment. The method comprises the steps: obtaining a to-be-processed intersection and an intersection reference line corresponding to the to-be-processed intersection according to an obtained road hitching request, and enabling the intersection reference line to comprise an entrance intersection reference line and an exit intersection reference line; for each entrance intersection reference line, determining a communication relationship between the entrance intersection reference line and the exit intersection reference line,hitching an entrance road, corresponding to the entrance intersection reference line, in the intersection and an exit road, corresponding to the entrance intersection reference line, in the intersection. According to the invention, automatic road hitching at the intersection is realized, and the road hitching efficiency and accuracy are high, so that the problems of low road hitching efficiency and high road hitching error rate caused by manual hitching of the road at the intersection are solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of map technology, and in particular, to a method and device for linking roads in an electronic map. Background technique [0002] Intersection refers to a level intersection, that is, a part where two or more roads intersect on the same level, and there is a conflict between traffic flows. When making a high-precision map, it is necessary to mount the roads in the intersection and connect the roads in the intersection. [0003] In the prior art, in the high-precision map, when connecting the roads in the intersection, generally the relevant personnel first determine the roads entering the intersection and the roads exiting the intersection in the intersection, and then check the relevant articulation rules , determine the roads entering the intersection and the roads exiting the intersection that have a articulated relationship, and articulate the roads entering and exiting the intersection tha...
