Researchers have developed a new method to improve the segmentation of point clouds from terrestrial laser scanning (TLS) in industrial settings, specifically for mechanical, electrical, and plumbing (MEP) systems. This approach addresses the challenges of extreme class imbalance and geometric ambiguity, where tail classes share similar primitives with dominant classes. By incorporating spatial context constraints, including Boundary-CB and Density-CB, the method enhances the accuracy of identifying safety-critical components like reducers and valves, leading to more reliable data for digital twin and Scan-to-BIM applications.
