Title:
Deep Learning for Semantic 3D City Model Extension: Modeling Roof Superstructures using Aerial Images for Solar Potential Analysis 
Abstract:
On a global scale, semantic 3D city models with Level of Detail 2 become more and more available. Automated generation of higher Level of Detail models is an active field of research, but low coverage of dense LiDAR or photogrammetric point clouds is a barrier. Therefore, this paper presents a novel approach for enriching semantic 3D city models with roof superstructures extracted from aerial images using deep learning. The method maps and classifies superstructures in 2D and subsequently tra...    »
