Abstract
En 中文
• Automated rebar extraction from lidar data collected at two distinct construction sites. • Iterative optimization of geometric features and neighborhood radius enhances the performance of the ML algorithm. • The method was validated on multiple datasets, demonstrating its robustness across environments. • Integration with Scan-to-BIM supports on-site QC and structural integrity in RC constructions.
