Abstract

The present application relates to a method, apparatus, device and storage medium for identifying lane lines in a general layout plan. Among them, the method includes: classifying all the lines in the general layout plan according to color and layer, and dividing the lines belonging to the same layer and having the same color into the same line set; for each of the line sets, extracting line pairs that meet the lane line characteristics; screening out suspected lane lines from the line pairs that meet the lane line characteristics in each of the line sets; verifying each of the suspected lane lines, and taking the suspected lane lines that pass the verification as the target lane lines in the general layout plan. The present application is used to solve the technical problem that the accuracy of lane line identification in the prior art is generally relatively low.
