Problems solved by technology

[0004] Although this single line description method is simple and convenient, it has some obvious defects, for example: 1) it can only describe lines with a fixed starting point and end point, if you want to change the starting point or target point, you must change the map; 2) you can only describe A method of running from the start point to the end point. To change the route or change the location of the lane change (or merge, which refers to the vehicle moving from one lane to another), the map must be changed

Embodiment Construction

[0047] The application will be described in further detail below in conjunction with the accompanying drawings.

[0048] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0049] 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.

[0050] 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 acce...

Abstract

The objective of the present application is to provide a method for road characterization comprising: acquiring a target road, wherein the target road comprises one or more road segments; determining one or more atoms corresponding to the road segments according to the link attribute information of the road segments A lane; determining lane association information between atomic lanes corresponding to the target lane; wherein the one or more atomic lanes and the lane association information are used to characterize the target lane. This application provides a functional and complete description of the objective connections of lanes within the target area, including lane connectivity and lane change feasibility.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a road representation technology and a technology for displaying road information. Background technique [0002] An unmanned driving system generally consists of a perception module, a positioning module, a planning module and a control module. The perception module obtains the current scene of the vehicle, the positioning module analyzes the scene to obtain the current position, the planning module plans the route according to the current position and the target position, and finally the control module issues the vehicle driving command. [0003] In order for the planning module to actually plan a drivable route from the starting position to the target position, a guidance map describing lane access in the relevant area is essential. See figure 1 In the presented scene, if the vehicle wants to drive from point P1 on road segment R1 to point P2 on road segment R2, the map...
