摘要：Large-scale heritage structures with historical value often suffer damage as a result of external forces. If they are to be rebuilt, while preserving their original appearance, the difficulties of reconstructing the often shattered remains must be addressed. In this paper, the south chimney of the Taiwan Tile Corporation′s Takao factory, which was seriously damaged during an earthquake, is used as the example. To develop the integrated technology of 3D laser scanning, with a Fuzzy c-mean algorithm and precision irregular 3D building digital model, eleven complete precision 3D digital models of the south chimney and a 3D digital model of the south chimney needed to be created from 2D architectural survey figures. Judging whether the positions of the undamaged remains match their original positions requires the use of 3D overlay recognition through position, size and appearance. The recognition results are successful for eight pieces of the remains, and the success matching rate is about 72%. The 3D digital recovery simulation model using a precision irregular 3D building digital model can improve the ability to rebuild in keeping with the original appearance, as well as reduce conservation costs in the rebuilding of large-scale heritage structures.
