Method for calibrating a system for the tri-dimensional acquisition of shape and system for implementing such method.

Abstract

Abstract The invention relates to a method for calibrating a system for the tri-dimensional acquisition of shape or form. The method comprises first the acquisition of the form of a calibration sight plate (4) having known geometrical reliefs in order to memorize gross information representative of echos of said sight perceived by the system. The adequation between the gross information and the geometrical definition information concerning said sight plate allows to establish the global transfer function of the system which, during measurements, allows to transform the gross information relative to any form or shape into coordinates (x, y, z) in an absolute reference frame.
