1. A method for geo-referencing an area by means of an imaging optronics system which comprises a step of acquiring M successive images by means of a detector, the imaged area being distributed between these M images, with M≧1, further comprising: measuring P distances d 1 , d 2 ,. .. , d P between the system and P points of the area, called range-found points, with P≧3, these range-found points being distributed in K of said images with 1≦K≦M, acquiring the positioning x m , y m , z m of the detector at the times of acquisition of the M images, measuring the attitude φ m , θ m , ψ m of the detector at the times of acquisition of the M images, acquiring the coordinates in these K images of the points called image points (p 1 , q 1 ), (p 2 , q 2 ),. .. , (p P , q P ) corresponding to the P range-found points, and estimating the parameters of exposure conditions x e , y e , z e , ψ e , θ e , φ e corresponding to the M images as a function of positionings, of attitudes, of distances and of coordinates of the image points, in order to correct the errors on the parameters x m , y m , z m , ψ m , θ m , φ m of each of the M images.
