Abstract
A method, in a system for aiding the guidance of a vehicle, for identifying marking stripes of road lanes. A road image is subjected to a convolution operation with a mask matrix so as to identify discontinuities present in the image. The resulting convolved image is compared with a threshold value and a representation of the marking stripes is determined. The mask matrix is set in such a way as to eliminate at least partially the discontinuities which do not correspond to the marking stripes.
