Využitie optickej 3D digitalizácie pri meraní rozmerov bezšvíkových oceľových rúr ťahaných za studena

Abstract

The paper deals with the use of a non-contact measurement method - optical 3D digitization (active triangulation/structured light method) - in measuring the dimensions (outer and inner diameter) of seamless cold drawn steel tubes. The paper focuses on three areas of tube measurement by 3D digitization: (1) measurement of dimensions at different tube sections, (2) measurement of dirty tube surface, (3) evaluation of measured values in terms of different settings of polygonization. The results of the measured values and findings serve as useful information when deciding on the choice of 3D digitization method for measuring seamless steel tubes.
