This project was committed to the Laboratory by Tenaris Dalmine, and was aimed at developing algorithms and measurement procedures for detecting defects in mandrels, for on-line inspection and quality control purposes.
The mandrels are scanned by using a laser slit: the profiles are acquired and the 3D map of the surface is obtained.

Careful analysis of the 3D map allows the detection of surface defect. The work is subjected to non disclosure agreements. The only available information is in the presentation below.
