Method of estimation of the offsets of image lines obtained by a sensor to travel spatial or airborne. The present invention relates to a method of estimation of the offsets of image lines of an image, referred to as "composite image ", constituted by the juxtaposition of image lines. The images lines represent the different portions of a scene on the surface (s) of a celestial body, acquired in succession by a line of cells of a sensor (10) on board a vehicle over said celestial body. The offsets of the images are induced by the aiming errors of the sensor (10) during the acquisition of the image line l . According to the invention, the lateral offset and / or longitudinal of an image line l, relative to an image line l, j different from i, as a function of a local model of the lateral and / or variation of the similarity between images different lines. The present invention also relates to a process for the formation of images formed on the basis of images lines having.
