The increasing availability of software tools for imageand range-based surveying and visualizing 3D objects has posed some issues relative to the need of integrating different contents (relative to data and metadata, structure and function) in a common Information System. In this work, we develop an integrated solution for a 3D GIS whose support is a global(More)
The introduction of laser-based photogrammetry in the surveying of Cultural Heritage provides an increasing volume of data, which requires multi-resolution approaches for analyzing and displaying the 3D information. Three-dimensional laser scanning provides accurate geometric and radiometric information about buildings façades and volumetric display of(More)
This contribution gives account of one of the results achieved by the group MAPA (Models and Algorithms for the digital documentation of Architectural Heritage) that integrates the IMAP3D group and the DAVAP group. The group work is based on the assumption that preservation of cultural heritage is a responsibility for the whole cartographic community and(More)
In this paper an integrated approach for modeling complex archaeological sites is developed. Particularly, we describe a 3D modeling pipeline which integrates laser scanning and low-cost Photogrammetry over an emblematic Jewish tanneries situated in Avila (Spain). Due to its inherent complexity and the relevance of the archaeological site, Jewish tanneries(More)
A sustainable urban environment requires an integration of documentation and management systems in surveying and planning applications for different kinds of services involving services and processes. Traditional GIS approaches are geo-referenced to 2D information or, more recently, to a virtualized environment arising from the reprojection of textured(More)
In the past few years, there exists an increasing relevance for surveying, protection, restoration and dissemination of Cultural Heritage. This trend is supported by the power provided by Information and Communication Technologies in two remarkable aspects: the ability of computer based tools for representing 3D objects from digital images and the(More)
There exists a very large amount of damaged buildings in Cultural Heritage. Common damages are related with structural deformations (lack of verticality, crashes, e.g.) and the degradation of the support (deteriorated materials, e.g.). A dense information is needed for both of them. Non-intrusive methods based in laser scans provide a 3d support with dense(More)
Three-dimensional modelling of urban environments is increasingly in a very fast way, and there is a diversifying demand of services and applications closed to virtual reality. The large diversity of formats, tools and products poses the need of developing software tools for sharing and exchanging information from context recognition. We propose an approach(More)
A real-time and reliable automatic video segmentation is one of the outstanding problems in Computer Vision with large applications to compression, transmission and motion analysis. In this paper, we show a novel approach based on the superposition of distance maps linked to centroids of mobile regions acting as attractors of homogenous regions to which(More)
The high complexity of the rehabilitation analysis of city centres requires a flexible multi-input and multi-output (MIMO) approach able to support the information arising from different sensors/techniques and to provide different levels of information to users with different requirements. In this paper, a MIMO approach to the capture, analysis and(More)
