In Europe, national acoustic classification schemes for housing exist in about ten countries. The schemes specify a number of quality classes, reflecting different levels of acoustic protection, and include class criteria concerning several acoustic aspects, main criteria being about airborne and impact sound insulation between dwellings, facade sound insulation and service equipment noise. The...

Abstract Terraces and tenements provide the facades upon which are inscribed texts decorative images. Embedded in walls, these ‘plaques’ convey meanings memories that saturate built environment with references to past. Evidence based on property surveys, maps archival documents form empirical basis from it is concluded images inscriptions presented a wider geo-political historical awareness eve...

We take advantage of human intuition by encoding facades into a procedural representation. Our user-assisted inverse procedural modeling approach allows users to exploit repetitions and symmetries of facades to create a split grammar representation of the input. Terminal symbols correspond to repeating elements such as windows, window panes, and doors and their distributions are encoded as the ...

Extracting 3-dimensional structure from real-world imagery and rendering it from unrestricted viewpoints is an important problem in computer vision, and increasingly, computer graphics. Despite many years of research, a system that automatically recovers realistic 3-D models from images remains elusive; most practical systems require signi cant human input. However, unlike automatic algorithms,...

Recent advances in scanning technologies allow large-scale scanning of urban scenes. Commonly, such acquisition incurs imperfections: large regions are missing, significant variation in sampling density, noise and outliers. Nevertheless, building facades often consist structural patterns and self-similarities of local geometric structures. Their highly-structured nature, makes 3D facades amenab...

The facade of the office levels has mechanically ventilated windows. The warm air in the room is extracted above the lighting units, so that the air also takes up their additional heat. Then this air is fed via specially shaped ducts at the level of the topmost transoms into the narrow cavity of the story-height ventilated windows. Here the air is warmed further by taking up heat from radiation...

Purpose We researched an automated and robotic facade maintenance robot. This robot can protect people against safety hazards, and save labour cost for building facade maintenance. Our platform is gondola type. Accurate and robust height estimation is necessary for automation. We propose a methodology for height estimation. Method Even though there are many sensor systems for height estimation,...

We present a set of algorithms that recovers detailed building surface structures from large sets of urban images containing severe occlusions and lighting variations. An iterative weighted-average algorithm is introduced to recover high-quality consensus facade texture. 2D and 3D methods are combined to extract microstructures, facilitating urban model refinement and visualization.
