CAD‐Based Photogrammetry for Reverse Engineering of Industrial Installations
Abstract: When designing an industrial installation, construction engineers often make use of a library of standardized CAD components. For instance, in the case of a servicing plant, such a library contains descriptions of simple components such as straight pipes, elbows, and T‐junctions. A new installation is constructed by selecting and connecting the appropriate components from the library. This article demonstrates that one can use the same approach for reverse engineering by photogrammetry. In our technique, the operator interprets images and selects the appropriate CAD component from a library. By aligning the edges of the component's wire frame to the visible edges in the images, we implicitly determine the position, orientation, and shape of the real component. For a fast object reconstruction the alignment process has been split in two parts. Initially, the operator approximately aligns a component to the images. In a second step a fitting algorithm is invoked for an automatic and precise alignment. Further improvement in the efficiency of the reconstruction is obtained by imposing geometric constraints on the CAD components of adjacent object parts.
