Recent advances in 3D reconstruction have enabled the automated generation of city models from LiDAR point clouds and aerial imagery. Although these methods produce visually convincing models, they are primarily designed for visualization purposes and often lack the geometric and topological quality required for Urban...

Abstract. Hybrid airborne imaging systems integrating oblique photogrammetric cameras and LiDAR sensors provide complementary geometric and radiometric information for high-fidelity 3D reconstruction. While LiDAR offers stable global geometric accuracy, photogrammetric reconstructions provide dense surface detail and r...

Abstract. The 3D reconstruction of cultural heritage artefacts plays a crucial role in documentation, conservation and dissemination. While recent advances in photogrammetry, laser scanning and neural rendering techniques have significantly improved the geometric accuracy and visual realism of digitised assets, the rec...
