Patent ID: 8879871

Claim:
A method for processing images in which the georeferencing of at least one digital image is performed by means of at least one picture model of said digital image and of a reference digital terrain model said digital image being obtained from a pair of digital images acquired in the same focal plane, said method comprising at least the following stages: stage of determining an intermediate digital terrain model from said pair of digital images, said stage of determining including at least a sub-stage that calculates, by correlaton, position shifts between the two digital images of said pair; stage of processing said intermediate digital terrain model and said reference digital terrain model by calculating, by correlation, position shifts between said reference digital terrain model and said intermediate digital terrain model to refine said picture geometry model of said digital image to be georeferenced to obtain a refined picture geometry model; stage of generating a final digital terrain model, from said pair of digital images and said refined picture geometry model, said stage of generating including: a sub-stage that calculates a model of position shifts between the two digital images of said pair from said refined picture geometry model and calculates differences between said model of position shifts and said calculated position shifts between the two digital images of said pair; and projecting said final digital terrain model and said digital image on the ground, in a geographical or cartographic system, for the purpose of georeferencing them.
