Improving the Realism of Existing 3D City Models

Within the paper, a novel approach for the reconstruction of geometric details of building façades is presented. It is based on 3D point clouds from terrestrial laser scanning. By a segmentation process, the approximate boundaries of the windows are detected and a cell decomposition of the façade is created. A classification of the cells determines a symmetric window arrangement of maximum likelihood.
