This article presents a methodological approach to the semantic description of architectural elements based both on theoretical reflections and research experiences. To develop this approach, a first process of extraction and formalization of architectural knowledge on the basis of the analysis of architectural treaties is proposed. Then, the identified(More)
The accurate 3D documentation of architectures and heritages is getting very common and required in different application contexts. The potentialities of the image-based approach are nowadays very well-known but there is a lack of reliable, precise and flexible solutions, possibly open-source, which could be used for metric and accurate documentation or(More)
This article presents a set of theoretical reflections and technical demonstrations that constitute a new methodological base for the architectural surveying and representation using computer graphics techniques. The problem we treated relates to three distinct concerns: the surveying of architectural objects, the construction and the semantic enrichment of(More)
This essay focuses on the fields of architectural documentation and digital representation. We present a research paper concerning the development of an information system at the scale of architecture, taking into account the relationships that can be established between the representation of buildings (shape, dimension, state of conservation, hypothetical(More)
Laser scanning enables to measure a huge number of 3D points in a few time. However, the creation of a 3D model from these data remains an involving work. We introduce a method to get this modeling task easier. Our approach is twofold. On the one hand, a camera is coupled to the laser scanner in order to drive the scan by image analysis. On the other hand,(More)
This paper discusses the fundamental issues of the real-time web-based visualization of complex reality-based 3D models. As web platform, we use NUBES, an innovative and powerful tool for sharing and analyzing reality-based 3D models online. A new automatic procedure for the setting-up and the uploading of 3D complex scenes into NUBES is presented,(More)
Aerial surveying is, in the domain of archeology and architecture, an exponential field of application and interest. Beyond the increasing flying capabilities and skills of existing UAV, the operational potentiality of the aircraft oversteps the imagination of their own creators. Initially conceived for robotic civilian and military surveying applications,(More)
