Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] Such as figure 1 As shown, the embodiment of the present invention provides a high-precision map sub-area compilation method, including the following steps:

[0044] S1, divide and back up the global data according to the geographical area according to the requirements;

[0045] S2, generating border information on the divided geographical areas to obtain basic data;

[0046] S3, compiling and processing, and partitioning to test and verify the compiled data;

[0047] S4. Merge and partition the test verification results into a global data graph and release it.

[0048] By dividing the global data into multiple regions, and then compiling the basic vector data i...

Abstract

The invention belongs to the technical field of high-precision electronic map making, and particularly provides a regional compiling method and system for a high-precision map, and the method comprises the following steps: carrying out the geographic region division of global data according to demands, and carrying out the backup; performing edge matching information generation on the divided geographic region to obtain basic data; compiling and processing the data into application data which can be used by the intelligent driving vehicle, and testing and verifying the compiled data in a partitioned manner; and merging and partitioning test verification results to generate a global data graph and publishing the global data graph. According to the scheme, global data are divided into a plurality of regions, and then basic vector data are compiled into application data which can be used by an intelligent driving vehicle in a regional manner. By means of the method, partition publishing and all-region publishing of data can be achieved at the same time, meanwhile, the all-region data publishing period is greatly shortened, and the freshness of a high-precision map in an intelligent driving automobile is improved to a certain degree. Wide application prospects are realized.

Description

technical field [0001] The present invention relates to the technical field of making high-precision electronic maps, and more specifically, to a method and system for compiling high-precision maps by regions. Background technique [0002] Autonomous driving refers to technologies that assist or replace human-driven cars. With the development of this technology, people's travel will be more convenient, and the influence of human factors in manual driving will be reduced, which can further improve driving safety to some extent. In the field of autonomous driving, map navigation is the prerequisite for end-to-end autonomous driving. Navigation technology is actually solving two problems. One is path planning, which is to calculate the number of roads or lanes covered by the end-to-end path; An action to ensure that the vehicle stays on the planned path. [0003] At present, high-precision electronic maps mainly serve self-driving vehicles, which provide lane-level planning ...
