Abstract

The embodiment of the invention provides an intersection information acquisition method and device, relates to the technical field of communication, and is used for improving the acquisition quality of intersection information. The method comprises the steps: according to road network data of an intersection, determining a target road section with the passing direction facing the intersection in all road sections outside the intersection and all drivable directions of the target road section; obtaining intersection information corresponding to a target drivable direction in each drivable direction of the target road section; and matching the obtained intersection information to the target road section.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a method and device for collecting intersection information. Background technique [0002] The emergence of electronic maps has brought great convenience to people's daily life. On the one hand, users can use electronic maps to find travel routes, such as bus routes, subway routes, vehicle travel routes, etc.; In addition to seeing the geographic location, you can also learn about the products, services, and contact information provided by some companies located in the corresponding geographic location on the map. [0003] The geographic base map is the core of the electronic map. It can be regarded as the electronic version of the traditional paper map. In addition to the map display, it also supports functions such as zooming in and out, address query, and route planning. In the course of daily use, the data content of the geographic basemap is...
