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...
