Abstract

The invention provides a method and a device for generating intersection data in a high-precision map, and the method comprises the steps: obtaining track points and stop line data, and grouping the track points and stop line data according to map tiles; judging whether the track points are located in the intersection or not by calculating the angle difference between each track point and the adjacent track point and the position relation between each track point and the adjacent stop line; expanding the tiles to which the track points in an intersection belong, and then regrouping; clusteringthe track points in the intersection in an expanded tile area to generate an external polygon of the same type of track points, and determining corresponding intersection data in a high-precision mapbased on the external polygon of the track points of the intersection. Based on independent calculation of track point classification and clustering processes in each tile, allocation of calculationtasks and design of a distributed structure can be facilitated, the data processing efficiency can be effectively improved, and intersection data can be conveniently and quickly generated.

Description

technical field [0001] The invention relates to the field of high-precision map production, in particular to a method and device for generating intersection data in a high-precision map. Background technique [0002] In the process of making high-precision maps, in order to generate high-precision map intersection data, it is necessary to input a large amount of trajectory and stop line data, and generate intersection data through unified processing of trajectory and stop line data, so as to make corresponding high-precision intersection maps. However, with the increase of collected data at intersections, it is difficult to achieve balanced deployment of data processing tasks through the traditional stand-alone processing method to process the input data in a unified order. , the efficiency of map making in the intersection area is still low. Contents of the invention [0003] In view of this, embodiments of the present invention provide a method and device for generating...
