Improved resolution of SAR sensors and advanced multipass interferometric techniques, such as tomographic SAR inversion (TomoSAR), opens up new possibilities of 4D (or even higher dimensional) imaging that can be potentially used to reconstruct dynamic models of entire cities, i.e., city models that can incorporate temporal (motion) behaviour along with the 3D information. Motivated by these chances,...
In this paper we present an approach that allows automatic reconstruction of building façades from 4D point cloud generated from tomographic SAR processing. The approach is modular and works by extracting façade points from the point density projected onto the ground plane. Individual façades are segmented using an unsupervised clustering procedure. Surface (flat or curved) model parameters of the...
Very high resolution SAR tomography using multiple data stacks from different viewing angles enables us for the first time to generate 4D point clouds of the illuminated area from space with a point density comparable to LiDAR. They can be potentially used for façade reconstruction and monitoring in urban environment. In this paper, we propose an approach for façade detection and reconstruction from...
