Building facade classification by architectural styles allows categorization of large databases of building images into semantic categories belonging to certain historic periods, regions and cultural influences. Image databases sorted by architectural styles permit effective and fast image search for the purposes of content-based image retrieval, 3D reconstruction, 3D city-modeling, virtual tou...

Within the paper we present the current activities of the Institute for Photogrammetry in cultural heritage documentation in Jordan. In particular two sites, Petra and Jerash, were recorded using terrestrial laser scanning (TLS). We present the results and the current status of the recording. Experiences drawn from these projects have led us to investigate more automated approaches to TLS data ...

Historic buildings have their own specialized and traditional techniques used in their construction. These are not generally practiced in modern buildings. Working with stone is very technical, laborious and time consuming job. It needs sensitivity and perfection both at workers 8and supervisor level. It is required to prepare different stone members in exactly the same size, proportion and des...

In this paper, we present an idea for a sparse approach to calculate camera poses from RGB images and laser distance measurements to perform subsequent facade reconstruction. The core idea is to guide the image recording process by choosing distinctive features with the laser range finder, e.g. building or window corners. From these distinctive features, we can establish correspondences between...

This papers describes an algorithm to estimate the precise position of facade planes in digital surface models (DSM) reconstructed from aerial images using an image-based optimization method which exploits the redundancy of the data set (along and across track overlap). This approach assumes that a facade is a vertical plane and that the heightfield is precise enough to generate hypotheses for ...

This project is an implementation of the CGA shape grammar as a plugin for Autodesk Maya R © to create a interactive environment for generating architectural facades. The CGA (Computer Generated Architecture) shape grammar, is a context-sensitive grammar created by Pascal Müller and Peter Wonka to procedurally generate buildings [Müller et al. 2006]. By implementing a subset of the shape gramma...

A short review for design consideration of two common materials used in facade and curtain walling is presented. The characteristics of light-weight facade enveloping a building are different from the conventional steel or concrete structures. Glass cannot crack like concrete and it is much more brittle than steel. Aluminum involves many buckling modes similar to but more common than steel. Owi...

Image classification are critically dependent on the features. In this paper, we perform an empirical feature evaluation task for building facade images. Feature sets we choose are basic features, color features, histogram features, peucker features, texture features, and SIFT features. We present an approach for regionwise labeling using an efficient randomized decision forest classifier and l...

A robotized manufacturing cell of pre-fabricated GRC (Glass Reinforced Cement) panels for construction industry has been developed by DISAM for the Spanish construction company Dragados, S.A.The main contribution of the developed system is the automatic program~ ming and control of the whole plan. The architect's 3D-drawing of the building facade done on a CAD system serves as input. From the C...
