Performance evaluation of automated 3D image-scan-based reverse engineering in architectural MEP pipe object modeling

This study aims to analyze the productivity of automatic 3D reverse engineering for architectural mechanical, electrical and plumbing (MEP) pipe objects modeling. Recently, 3D image scan-based reverse engineering is emerging technology in facility management, operation domain. However, because a large amount of scanned point cloud data is so complex and difficult, it requires manual task additionally. Manual-based reverse engineering occurs low-productivity, data loss and error. We suggest the process of automatic 3D reverse engineering work for modeling pipeline which occupies the largest part of MEP phase. Furthermore, this study analyzes the productivity effect related to the proposed method. The results show that the productivity is improved from 118 to 162% (average work effectiveness: 141%). © 2016, Korean Spatial Information Society.
