In this paper we present a practical approach for generating anocclusion-free textured 3D map of urban facades by the synergistic use ofterrestrial images, 3D point clouds and area-based information. Particularly indense urban environments, the high presence of urban objects in front of thefacades causes significant difficulties for several stages in computationalbuilding modeling. Major challenges lie on the one hand in extracting complete3D facade quadrilateral delimitations and on the other hand in generatingocclusion-free facade textures. For these reasons, we describe astraightforward approach for completing and recovering facade geometry andtextures by exploiting the data complementarity of terrestrial multi-sourceimagery and area-based information.
