METHOD AND DEVICE FOR LANE DETECTION

摘要

The invention relates to a lane detection method wherein a digitized color image (10) of a roadway (12) is processed using the following steps: determining road markings the gray tone of which is below the gray tone of the roadway (S18), setting the gray tone of the markings determined in this way to a value above the gray tone of the roadway (S20), and outputting the image so processed and modified to be processed by way of a lane detection algorithm for monochrome images (S22).
