The paper presents a 2D laser profilometer with the triangulation head. The system has been equipped with a robust algorithm for effective elimination of measurement artefacts typical for triangulation systems. The approach consists in multiple scanning of the object surface for various angular positions, followed by a process of fusion of these data images. The location of the rotation axis of the object has been calculated with the use of the specially developed calibration gauge which is crucial for a precise data assembling procedure. The paper covers the sequence of data processing, the design of the profilometer as a whole, system control and a collection of algorithms verified experimentally.
