[Termes IGN] surface B-spline rationnelle non uniformeRésumé : (auteur) This paper presents an innovative procedure to create parametric building information modelling (BIM) objects from point clouds of complex architectural features. BIM technology requires an advanced parametric representation of the geometry involving spatial relationships, constraints and material properties. The aim of the procedure is a BIM-based reconstruction methodology that preserves the level of detail encapsulated in photogrammetric and laser-scanning point clouds, and relies on non-uniform rational basis splines (NURBS) curves. The particular case of architectural objects with irregular shapes is addressed due to the lack of commercial BIM software able to handle such buildings. An actual case study made up of 7·5 billion points is discussed to demonstrate the use of the proposed procedure with huge point-cloud datasets.

[Termes IGN] traitement automatique d'imagesRésumé : (Auteur) An innovative methodology that combines central perspectives and panoramic gnomonic projections into an integrated bundle block adjustment is discussed. The use of both kinds of images generates metric products with a superior level of detail (image resolution) compared with conventional central perspectives alone, whilst achieving the accuracy of the latter. The entire methodology is intended as a low-cost solution to improving the ground sampling distance over that achievable with single exposures by conventional modern terrestrial cameras. Very high-resolution close-range images can be automatically generated and oriented with a rigorous multi-step procedure that integrates both types of images within a unified least squares adjustment. The advantages and disadvantages of the proposed approach are analysed from both theoretical and practical points of view and illustrated through a series of examples.

The specific characteristics required in cultural heritage applications have been investigated and are reported, where two main fields are considered: radiometric analyses using multispectral images and 3D surveying for geometric deformation analysis by means of photogrammetry and laser scanning. The activities described were accomplished in interdisciplinary teams, composed of photogrammetrists, art-historians, restorers and experts of non-destructive diagnostic techniques.

[Termes IGN] semis de pointsRésumé : (Auteur) In this paper an automated methodology is presented (i) to orient a set of close-range images captured with a calibrated camera, and (ii) to extract dense and accurate point clouds starting from the estimated orientation parameters. The whole procedure combines different algorithms and techniques in order to obtain accurate 3D reconstructions in an automatic way. The exterior orientation parameters are estimated using a photogrammetric bundle adjustment with the image correspondences detected using area- and feature-based matching algorithms. Surface measurements are then performed using advanced multi-image matching techniques based on multiple image primitives. To demonstrate the reliability, precision and robustness of the procedure, several tests on different kinds of free-form objects are illustrated and discussed in the paper. Three-dimensional comparisons with range-based data are also carried out.
