Reduction of building façade model complexity using computer visionReduction of building façade model complexity using computer vision Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2018-06-272016en3D Building façade reconstruction enables the implementation of delicate actions related to restoration, support and presentation of architectural structures. In particular, model complexity can be significantly reduced through the incorporation of computer vision and image processing tools, aiming towards the estimation of structural 3D feature characteristics instead of their actual GPS specification. In this paper we present a strategy for constructing reduced-complexity 3D models, which combines stereo vision images and morphological processing methods. Initially, the building skeleton is extracted and modeled with the use of Hough transformation and Active Contours. Subsequently, the building's façade depth map is derived using the stereo camera layout, for the refinement of inner skeleton details, such as the protrusion of windows or doors. These image-driven features are fused with Georeferenced data in order to complete the full building's skeleton model. The proposed reconstruction framework is tested on the site of Neoria buildings, a historical (Venetian) site in Chania, Crete, Greece.http://creativecommons.org/licenses/by/4.0/454-459IEEE International Conference on Imaging Systems and TechniquesIST 2016 - 2016 IEEE International Conference on Imaging Systems and Techniques, Proceedings Paravolidakis Vasileios Παραβολιδακης Βασιλειος Bacharidis Konstantinos Μπαχαριδης Κωνσταντινος Sarri Effrosyni Σαρρη Ευφροσυνη Ragia Lemonia Ραγια Λεμονια Zervakis Michail Ζερβακης Μιχαηλ Institute of Electrical and Electronics Engineers 3D building reconstruction Active contours model Fusion of camera with geo-reference data Stereo vision
