Abstract

The invention provides a generation method, device and system of lane lines of a map and a storage medium. The method comprises the following steps: acquiring a target reflected value base map corresponding to a surrounding environment of a UGV (unmanned ground vehicle); dividing lane lines on a road, on which the UGV drives, so as to obtain reference lane lines; performing semantic segmentation on the target reflected value base map, so as to obtain a gauge point set corresponding to the lane lines; calibrating the reference lane lines according to gauge points in the gauge point set, so as to obtain calibrated lane lines. The clean and continuous lain lines can be automatically generated, so that the clear lane lines cannot be acquired by the UGV, which is caused by the problems that thelane lines on the road are covered, worn and the like, is avoided, and the problems of incompleteness and breaking of the lane lines generated according to the reflected value base map are also avoided. Therefore, the UGV can 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...
