SYSTEM AND METHOD FOR LOCATING IMPACTS ON AN EXTERNAL SURFACE
First Claim
1. A method for locating impacts on an external surface of a body comprising the following steps:
- a) modeling the body in a first database of a control unit to obtain a virtual model of said body in a virtual system of reference axes;
b) modeling, in a second database of the control unit, of a plurality of clouds of points in the virtual system of reference axes, each cloud of points, called an inspection zone, representing a portion of the external surface of the body;
c) selecting an inspection zone via a man-machine interface of the control unit;
d) transfering, by a central processing unit of the control unit, the coordinates of each point of the first and second databases from the virtual system of reference axes to a geographic system of reference axes;
e) determining the coordinates, in the geographic system of reference axes, the initial position of a flying drone in communication with the central processing unit, the drone being equipped with a range finder;
f) calculating, by the central processing unit, a flight plan of the drone such that it scans, via the range finder, the selected inspection zone;
g) creating, by the central processing unit, a 3D meshing of the selected inspection zone scanned by the range finder;
h) detecting by the central processing unit the impacts, by a comparison between the 3D meshing and the virtual model of said aircraft and calculating, by the central processing unit, the coordinates of each impact in the geographic system of reference axes and the virtual system of reference axes.

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; transfering 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.
