Abstract
This paper describes a displacement measuring technique using a laser-beam scanner for detailed non- contact mapping of the interior geometry of pipes. The technique, which is based on optical measurement using triangulation, measures radial displacement with an accuracy of ± 0.2 mm for radii between 33 and 42.5 mm. A mapping system using this technique with automated data-acquisition and three-dimensional rendering of the interior is also described and its effectiveness is illustrated with experimental results. This paper also describes an automated system for detecting pipe wall deformation and presents preliminary results using this system.
