Abstract: A method for locating external surface impacts on a body. The steps are: modeling the body in a control unit first database to obtain a virtual body model in a virtual system of reference axes; modeling, in a second database, a plurality of clouds of points in the virtual system, each cloud defining an inspection zone representing an external surface portion; selecting an inspection zone; transferring the coordinates of each point of the first and second databases to a geographic system of reference axes; determining geographic coordinates of an initial position of a range finder equipped flying drone communicating with the processing unit; calculating a drone flight plan to scan the selected inspection zone; creating a 3D meshing of the scanned inspection zone; detecting the impacts by comparing the 3D meshing and the virtual aircraft model and calculating the coordinates of each impact in the geographic and virtual systems.
