3D Building Reconstruction
TL;DR:
We developed a building fine modeling method based on point cloud segmentation and pointcloud ICP algorithm. Using handheld LiDAR scanners, we generated 3D point clouds of buildings and applied a semantic segmentation model (PointNet++) to improve accuracy and robustness in complex scenes. A geometry–semantic constrained reconstruction algorithm was further designed to restore missing structures. The method achieves efficient and high-precision 3D building models, accurately representing details such as walls, roofs, doors, and windows.
