<p>The method of fast impingement detection between at least two bodies essentially comprises the steps of a) acquisition of three-dimensional image data of the at least two bodies (1;2) and thereof obtaining a data set of points on the surface of the bodies (1;2) by means of a computer (11); b) attaching a reference element (5;6) comprising at least three markers (7) each at each of the bodies (1;2) and measuring the three-dimensional coordinates of the markers (7) with respect to an on-site three-dimensional system of coordinates (4) by means of a position measurement device (14) and during displacement of the bodies (1;2); c) computing if and where two surface points (9;10) being each on the surface of separate body (1;2) and being closest to each other coincide within the on-site three-dimensional system of coordinates (4) by means of the computer (11).</p> |
