Abstract

The embodiment of the invention provides a lane line identification method, device and equipment and a storage medium. The method comprises the following steps: acquiring an image of a lane line, a reflection value base map of a surrounding environment and historical vehicle track information; Determining a target reflection value base map of the lane line from the reflection value base map; Determining target track information from the historical vehicle track information; And determining a lane line from the image of the lane line according to the target reflection value base map and the target track information. The accuracy of the lane line can be improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a lane line recognition method, device, equipment and storage medium. Background technique [0002] With the development of artificial intelligence and intelligent transportation technology, unmanned vehicles based on unmanned driving technology will become the mainstream way of travel. [0003] In order to ensure that the unmanned vehicle can abide by the traffic rules and ensure driving safety, the unmanned vehicle needs to recognize the lane lines on the road during the driving process. At present, the lane lines of unmanned vehicles are usually obtained based on the reflection value base map of the lane lines. [0004] However, the position of the lane line produced based on the reflection value base map is not accurate, which makes the lane line of the unmanned vehicle not accurate enough, which is not conducive to the safe driving of the unmanned...
