Patent ID: 8107684

Claim:
A method for geolocalization of at least one stationary target P from an aircraft by means of a passive optronic sensor and by software implemented on electronic cards, said method comprising the following steps: acquiring by a sensor of at least one image I 1 containing the target P from a position C 1 of the aircraft and of an image I 2 containing the target P from a position C 2 of the aircraft, the images I 1 and I 2 having an area of overlap; identifying in said overlap area of the target P common to the two images I 1 and I 2 and determination of the position of the common target P in each of the two images; calculating a distance d between a point C, of coordinates relative to C 1 and C 2 , and the target P, as a function of the angle β 1 between a reference direction and the line of sight of the image I 1 , the angle β 2 between the same reference direction and the line of sight of the image I 2 , and of the position of the target P in the image I 1 and in the image I 2 ; and P being defined in a terrestrial reference frame by its x-coordinate X and its y-coordinate Y relative to the projection on the ground of the aircraft C, calculating X and Y for the target P as a function of the distance d.
