Embodiment Construction

[0049] 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 creative efforts fall within the protection scope of this application.

[0050]This application is mainly used for virtual road sections, which may refer to road sections with only central lane lines and no side lane lines. In one embodiment, a virtual road section may refer to a road section in which only the center lane line is actually marked (that is, offline), but the side lane lines are not actually marked in the road section, and the road section is included in the map (that is, online) The side lane markings for this road segment are also not marked. In...

Abstract

The embodiment of the present application discloses a lane line generation method, device, device, and storage medium, wherein the method relates to the fields of automatic driving technology and artificial intelligence technology, and the method includes: obtaining the actual side lane line of the first road section, and The center lane line of the second road section; according to the actual side lane line of the first road section, determine the width information of the second road section; from the center lane line of the second road section, extract the information used to reflect the first road section The center position point of the contour of the center lane line of the second road segment; according to the center position point and the width information of the second road segment, determine the side position for reflecting the outline of the virtual side lane line of the second road segment point; generating the virtual side lane line of the second road segment according to the side position point. Through the present application, the accuracy and efficiency of generating side lane lines can be improved.

Description

technical field [0001] The present application relates to the fields of automatic driving technology and artificial intelligence technology, and in particular to a lane line generation method, device, device and storage medium. Background technique [0002] Autonomous driving technology involves using video cameras, radar sensors, and laser rangefinders to understand surrounding traffic conditions and navigate the road ahead through a detailed map (collected by human-driven cars). In practice, it has been found that if the road ahead lacks side lane lines (such as left lane lines and right lane lines), it is easy to cause navigation errors, and in turn, users cannot reach their destinations efficiently. It can be seen that in the autonomous driving scene, lane lines, as important static semantic information, are of great significance to vehicle navigation. [0003] At present, side lane lines are mainly added to roads lacking side lane lines manually. Due to the influence o...
