A new system is being developed with which the corro-
sion course can be measured in pipes with ultrasound
and be shown three-dimensional. This work is done in
close cooperation with the MBQ GmbH. The sphere of
activity is the nondestructive inspection of wall thick-
ness in pipeworks. At the moment corrosion investiga-
tions are carried out by means of radiological examina-
tion or conventional ultrasonics. At this, only a fraction
of the surface is inspected.
The aim of the research project is to track an ultrasonic
sensing head in 3-d by a stereo camera sensor while
it is moved over the pipe surface. The position mea-
surement should take place through the evaluation of
optical fiducial marks. A new system originates which
allows a three-dimensional representation, interpreta-
tion, and storage of ultrasonic data. In this way, the
whole pipe surface in the effective range of the stereo
camera sensor can be captured without gap to ensure a
nearly one hundred percent evaluation of wall thickness.
