Abstract

The present disclosure relates to a method for updating lane lines on a map. The method comprises obtaining a first set of sampling points of lane lines from a map and obtaining a second set of sampling points of lane lines in a driving scenario based on vehicle sensor information. The method further comprises updating the first set of sampling points on the map based on the positional relationship between the first set of sampling points and the second set of sampling points. In this way, existing maps and current sensor information can be fused to update the position of map points based on lane line detection points in real driving scenarios. Moreover, global lane lines can be formed based on the map's topology, thereby avoiding the limitations of sensor detection range and enabling the updating and expansion of perception results. As such, examples of the present disclosure are capable of increasing the accuracy of lane line updates on a map.
