Title: An End-to-End Architecture for Accurate Roof Structures Topological Reconstruction from Imagery Guided by Height
Abstract:
We proposed a novel end-to-end pipeline for complex building roof structural reconstruction. The pipeline takes the roof imagery and the corresponding digital surface model as the inputs and predicts the roof structure topology as a waterproof graph without redundancy. Our contributions are 1) An end-to-end pipeline for accurate LoD2.5 building roof structure extraction and modeling from very high-resolution aerial or satellite imagery, assisted by DSM; 2) A feature fusion architecture that fuses RGB images with height prior and enhance structural understanding; 3) The pipeline demonstrates robust performance under challenging imaging conditions, including occlusions and shadowing. We conduct experiments on three open-source datasets and results show that our work outperforms the state-of-the-art.
