Abstract
En 中文
• End-to-end automated as-built management of retaining grid frame structures. • Segmentation, cross-sectioning and dimension extraction performed on point clouds. • Field test on a 60 m curved slope achieved 0.02 m mean dimensional error. • Method reached F1 = 0.92 for slope surface detection on TLS and HLS datasets. • Replaces hazardous rope-work with safe remote point-cloud inspection.
