Abstract
A method for geo-referencing an area by an imaging optronics system which comprises acquiring M successive images by a detector, the imaged area being distributed between these M images, with M≧1. It comprises: measuring P distances d1, d2, . . . , dP between the system and P points of the area, called range-found points, with P≧3, distributed in K of said images with 1≦K≦M; acquiring the positioning xm, ym, zm of the detector at acquisition of the M images; measuring the attitude φm, θm, ψm of the detector at acquisition of the M images; acquiring the coordinates in these K images of image points (p1, q1), (p2, q2), . . . , (pP, qP) corresponding to the P range-found points; and estimating the parameters of exposure conditions xe, ye, ze, ψe, θe, φe corresponding to the M images as a function of positionings, of attitudes, distances and coordinates of the image points, to correct errors on the parameters xm, ym, zm, ψm, θm, φm of each of the M images.
