Abstract

The invention provides a map description file generation method and device. The method comprises the following steps: acquiring description information according to a source map description file; determining a non-connection road and a connection road corresponding to the non-connection road according to the description information; receiving preset information corresponding to road parameters of each non-connected road input by a user on a non-connected road configuration interface, and generating first description information according to the preset information; according to the first description information of the non-connection road, determining second description information of the corresponding connection road; and generating a target description file according to the first description information and the second description information, so that rapid generalization of a road map is realized, the time for drawing a large number of road maps is shortened, and the workload of employees is reduced.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular, to a method and apparatus for generating a map description file. Background technique [0002] The general description scheme for existing autonomous driving simulation scenarios is the OpenX series of standards, including: OpenDRIVE, OpenSCENARIO and OpenCRG. The static part of the simulation test scene (such as road topology, traffic signs and markings, etc.) is described by OpenDRIVE files, and the surface details of the road (such as potholes, cobble roads, etc.) are described by OpenCRG files, and the dynamic part of the simulation test scene (such as traffic car behavior) is described by the OpenSCENARIO file. [0003] In order to ensure the safety of automatic driving, it is necessary to use a large number of simulation scenarios to test the automatic driving algorithm, but the current simulation scenarios are all drawn manually, especially the stati...
