Embodiment Construction

[0050] The application will be described in further detail below in conjunction with the accompanying drawings.

[0051] In a typical configuration of the present application, a terminal, a device serving a network, and a computing device include one or more processors (CPUs), input / output interfaces, network interfaces, and memory.

[0052] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0053]Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memor...

Abstract

The invention aims to provide a method and device for use and creation of road network map information. The road network map information is obtained, wherein the road network map information includesa road network unit and unit description information corresponding to the road network unit, the road network unit includes at least one of the following items: a road network coordinate system, roadnetwork points, road sections, parking spaces, static obstacles, and parking observation points; the road network map information is used. Compared with the prior art, the method and device can greatly extend content forms and use scenes of the road network map information, and satisfy specific requirements on the road network information in different scenes, such as limited scenes, for example, the method and device can help to improve the vehicle driving execution rate in the limited scenes, can provide more valuable information for control of vehicle driving, and can also provide support for common traffic scenes.

Description

technical field [0001] This application relates to the field of automatic driving, in particular to a technology for using and creating road network map information. Background technique [0002] The current unmanned driving industry is divided into two technical directions, one of which is the research of unmanned driving technology for the open world, that is, unmanned driving on roads, expressways and other real public transportation roads. The technical requirements of one direction are universal and applicable, and can deal with all possible situations in traffic; the other direction is the research of unmanned driving in limited scenarios, such as indoor and outdoor parking lots, parks, airports, workshops, etc. Human-driving technology needs to be scene-specific, able to give priority to meeting the specific needs of limited scenes, while taking into account some situations that occur in ordinary traffic. Existing high-precision maps mainly provide road information i...
