A Lightweight Rail Tread Extraction Framework for Ballastless Track LiDAR Point Clouds Using Multi-Stage Filtering and Curvature-Guided Region Growing

Urban rail transit infrastructure inspection increasingly relies on Light Detection and Ranging (LiDAR) due to its capability for efficient and high-precision 3D data acquisition. However, robust rail tread segmentation in ballastless metro environments remains challenging due to boundary leakage, interference from geo...
