Title: A Framework for 3D Reconstruction of Concrete Box-Girder Interiors from Point Cloud Data Authors: Taegyu Kim, Seunghun Im, Duho Chung, Sungwoo Cho, Ilhyeong Shin, Hyeongu Ji, Hyoungkwan Kim Abstract: Inspection of concrete box-girders is essential for ensuring the structural performance of a PSM bridge throughout its service life. With advances in 3D sensing and point cloud processing, 3D data-based approaches have been increasingly applied to bridge inspection. This paper presents a 3D reconstruction pipeline for concrete box-girder interiors that ...
