The invention concerns a method for geolocalization of one or more stationary targets from an aircraft using a passive optronic sensor. It includes the following steps: acquiring with the sensor at least one image I1 containing the target P from a position C1 of the aircraft and an image I2 containing the target P from a position C2 of the aircraft, said images I1 and I2 having an overlapping zone; identifying in said overlapping zone at least one target P common to both images I1 and I2 and determining the position of each of the two images; calculating the distance d between each target P and a point C located for example in the neighbourhood of C1 and C2, based on the angle F1 between a reference direction and the line of sight of image I1, the angle F1 between the same reference direction and the line of sight of image I2, the position of each target P in image I1 and image I2; calculating the positions of the targets relative to the projection on the ground of the aircraft in C, based on the distances d in the terrestrial reference frame. |
