Plane-Based Robust Registration of a Building Scan with Its BIM

The registration of as-built and as-planned building models is a pre-requisite in automated construction progress monitoring. Due to the numerous challenges associated with process, it still performed manually. This research study proposes an method that aligns point cloud its model using planar features. proposed extracts processes all plane segments from both models, then—for models—groups parallel into clusters subsequently determines directions these eventually determine range possible rotation matrices. These matrices are then evaluated through computational framework based on postulation concerning matching models. measures correspondence between cost algorithm, thus identifying segments, which ultimately leads determination transformation parameters correctly register model. was validated by applying different datasets. results proved robustness terms accuracy efficiency. In addition, also correct support for buildings under construction, inherently incomplete, bringing step closer practical effective
