Abstract :
This paper presents a real-time method for crack detection used in our apparatus of road characterisation - AMACreg. The method based on a set of image processing tasks : bi-level thresholding, morphological operation, and projection. The method have been tested on three kinds of images: the first ones are images taken in laboratory in static mode and ldquoideal rdquo lighting condition, the second ones are static images taken by a normal camera in static mode without control of lighting condition and the third ones are images acquired by AMAC reg. The result of these tests, in addition, verified the quality of the apparatus AMAC reg in acquiring road images.
