Claim:
1. A method for focusing a beam of a high energy radiation source, particularly a laser beam, on a reference point on the surface of a flying object in flight, including the following steps: recording a number of consecutive two-dimensional images of the flying object in flight with an imaging method using an image acquisition device; determining the trajectory of the flight path of the flying object as a sequence of three-dimensional waypoints; simultaneously determining the line of a sight angle between the image acquisition device and the position of the flying object in synchronization with the image; calculating a three dimensional model of the flying object from the two-dimensional images recorded on the basis of the relative geometry to be calculated from the line of sight angles calculated and the trajectory obtained, and on the basis of predefined model assumptions about the flying object; displaying the currently acquired two-dimensional image of the flying object in flight via an image reproduction device; marking the reference point on the displayed two-dimensional image of the flying object; calculating the three-dimensional reference point on the surface of the flying object starting from the two-dimensional reference point marked using the three-dimensional model of the flying object calculated, and focusing the beam of the high energy radiation source on the three-dimensional reference point and causing the focus point of the beam directed at the reference point to track said reference point.
