Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0046] Since intersections in the prior art are represented by "dots", this representation ignores the passing rules inside the intersection and cannot meet the requirements for map data in the automatic driving stage.

[0047] Based on this, the application provides a method for generating road data, such as figure 2 As shown, it specifically includes the following steps:

[0048] Step S101: From the collected high-precision trajectory point sets, obtain a target high-precision t...

Abstract

The present application provides a road data generation method and device, wherein the road data generation method includes: from the collected high-precision track point set, obtain another lane from one lane of the first road to the second road at the intersection A set of target high-precision track points formed in the course of the lane; curve fitting is performed on the set of target high-precision track points to obtain the lane centerline of the target lane; wherein, the target lane is connected to the One lane of the first road and the other lane of the second road. This application uses the centerline of the lane to represent the intersection, so that it can drive along the centerline of the lane during automatic driving, so as to meet the demand for map data in the automatic driving stage.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for generating road data. Background technique [0002] With the continuous advancement of science and technology, technologies related to autonomous vehicles have gradually emerged. Self-driving vehicles, also known as unmanned vehicles or computer-driven vehicles, are intelligent vehicles that realize unmanned driving through on-board computers. [0003] The self-driving vehicle is equipped with an on-board computer. Before starting the automatic driving, the user can input the starting point and destination point to the on-board computer, and determine the navigation path from the starting point to the destination through the path planning algorithm. The on-board computer guides the vehicle through the navigation path. drive. [0004] The road data in the existing electronic map adopts the "line-point-line road model", that is, in the ro...
