Abstract
Three-dimensional
(3D) reconstruction of as-built pipelines is used for such things as plant
operation, maintenance, and expansion of existing facilities. Unfortunately, the current method of
generating 3D models of as-built pipelines from laser-scanner data requires
costly and labor-intensive manual processes.
Authors describe an automated as-built pipeline-modeling method. The proposed approach consists of two
functional parts. The first is
segmentation of cylindrically formed pipelines based on medial axis
approximation and curve skeleton extraction. The second is surface-model generation of
cylindrically formed pipelines based on a parametric modeling method. An initial experiment was performed at an
operating plant facility to evaluate and validate the proposed method. Preliminary results show that the proposed
method enables reliable 3D as-built models of pipelines, which could be
successfully incorporated into the development of an as-built plant information
modeling method. It could assist in such
maintenance tasks as inspection, repair, replacement, or revamping.
