Abstract

The method according to this invention provides for a scan using an optoelectronic system and is specifically a laser scan of a three dimensional surface that is to be reproduced. The surface is gone over by a sensor made up of four laser devices used to get the coordinates of different point on the surface to be scanned. Specifically the coordinates of the three points according to the vertices of an equilateral triangle and a fourth point an equal distance from the others. From the coordinates of the first three points it receives the normal directing cosines to the passing surface for the fourth point. Even the spatial coordinates are received. This makes it possible to determine the accuracy of the processing of the surface.
