Ultrasonic Point Cloud-Based Segmentation and Quantification of Internal Defects in Concrete Structures

Accurate detection of internal defects in concrete structures is critical to structural safety. This study proposes a three-stage method for segmentation and geometric quantification of defects from 3D ultrasonic point clouds to support non-destructive testing (NDT). Sparse point clouds are densified by grid-based, aco...
