Abstract

The invention relates to a map diversion zone generation method, device and equipment. The method comprises the following steps: acquiring each lane line on a map intersection area; according to the unit line segments in the lane lines, selecting two unit line segments with overlapped head points as two starting side lines, and taking the overlapped head points as starting points; respectively generating two tail point sets according to each starting side line and the tail point of each unit line segment which is continuously connected with the starting side line; judging whether coincident tail points exist in the two tail point sets or not; if yes, taking the overlapped tail point as a junction-dead point; and taking the two lane lines of which the head points are the starting points and the tail points are the ending points as two boundary lane lines, and drawing a diversion line in an area surrounded by the two boundary lane lines to obtain a diversion zone. According to the scheme provided by the invention, the diversion zone can be automatically generated, the drawing efficiency of the high-precision map is improved, and the navigation experience is optimized.

Description

technical field [0001] The present application relates to the technical field of navigation, and in particular to a method, device and equipment for generating a map diversion strip. Background technique [0002] With the development of technologies such as artificial intelligence and autonomous driving, the construction of intelligent transportation has become a research hotspot, and high-precision maps are an indispensable part of the construction of intelligent transportation data. Making high-precision maps requires drawing diversion strips, which can provide data support for navigation in application scenarios such as autonomous driving. The diversion belt is mainly used at overly wide, irregular or complex intersections. Its function is to regulate vehicles to drive on the road section, intersections and entrances and exits according to the prescribed route, and warn drivers not to press or cross the line. [0003] However, in the related art, the generation of divers...
