Building Facade Completion Using Semantic-Synchronized GAN

Due to the difference in high-rise distance, laser incident angle, and occlusion, incomplete point cloud of building facades is incomplete. The existing point cloud facade completion work does not fully explore the semantic constraints. Thus, it is difficult to deal with the facades with large-area missing. This paper proposes a novel facade completion framework for point clouds. By introducing semantic constraints and semantic-synchronized GAN, we solve the facade completion problem with large-area missing while the semantic consistency is augmented.
