Abstract

The present invention provides a method, device, system and storage medium for generating map lane lines. The method includes: obtaining a target reflection value base map corresponding to the surrounding environment of an unmanned vehicle; Refer to the lane line; perform semantic segmentation on the base map of the target reflection value to obtain a set of marking points corresponding to the lane line; perform calibration processing on the reference lane line through the marking points in the set of marking points to obtain the calibrated lane line . In this way, clear and continuous lane lines can be automatically generated, avoiding the failure of unmanned vehicles to collect clear lane lines due to problems such as occlusion and wear of the lane lines on the road, and also avoiding the lane line generated based on the reflection value base map. The problem of missing and disconnected lines enables unmanned vehicles to drive safely according to the lane lines.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to a method, device, system and storage medium for generating map lane lines. Background technique [0002] With the development of automobile technology, unmanned vehicles have begun to be applied and developed. During the driving process of the unmanned vehicle, it is necessary to provide lane line information for the unmanned vehicle, so that the unmanned vehicle can automatically drive according to the lane line. [0003] In the prior art, unmanned vehicles can collect lane lines through cameras and other equipment, and then perform automatic driving control according to the collected lane lines. [0004] However, in the existing technology, the lane lines on the road are often blocked by obstacles, worn out, etc., so that the lane lines collected by the unmanned vehicle have problems such as blurring and disconnection, which affect the normal driving of the un...
