Abstract :
This paper proposes a new method of automatic registration of urban remote sensing images that has combined bilinear interpolation which is a classic method of image registration and road networks which are the characters of urban remote sensing images. It comprises of extracting the road network in an urban and computing the Ground Control Points (GCP) from the road junctions, then estimating the parameters of the mapping function and transforming the sensed image at last.
