Abstract:This research focuses on two topics. The first topic is the simplification of point clouds. The simplification algorithm developed for this project is based on Quadric Edge Collapse Decimation (QECD). It uses Building Information Models (BIMs) as semantic priors to help simplify point clouds and can achieve better planar simplification and detail preservation than traditional algorithms. The second topic is the alignment of point clouds to BIMs. The tool developed is a semi-supervised tool, which allows users to select point matches between corresponding point clouds and BIMs, and it aligns point clouds to BIMs accurately within minimal time.
