Method and device for fast detection of repetitive structures in the image of a road scene

An image processing module allowing the identification of at least one same point appearing on each image of a sequence of images, said sequence of images comprising a first image, a second image and a third image generated respectively at a first instant, at a second instant, later than the first instant, and at a third instant, later than the second instant, by a camera mounted in an automotive vehicle, said image processing module configured to:

• detect a plurality of identical points in each image of the sequence of images relating to a plurality of repetitive patterns in each image of the sequence of images,
• calculate a depth (ZA1(t1), ZA2(t1)) at the first instant of the point in space corresponding to said identical point of the second image for each identical point detected in the second image of the sequence of images,
• calculate a depth (ZA3(t1), ZA4(t1)) at the first instant of the point in space corresponding to said identical point of the third image, for each identical point detected in the third image of the sequence of images, and
• identify in the second image and in the third image, identical points corresponding to the points in space for which the calculated distance is identical, these points in space representing respectively in the second image and in the third image one and the same real point.
