[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] vectorisationRésumé : (auteur) This paper introduces an innovative automatic road-vectorisation algorithm based on dynamic pixel clustering using particle swarm optimisation. A new cost function is designed to optimise the number and position of road keypoints and is capable of deriving road centrelines without considering geometric, spectral or topological characteristics in the road model. The algorithm is applied to different high-resolution images (IKONOS, QuickBird and aerial photographs) and is evaluated with respect to RMSE, correctness and completeness. Moreover, a new quality parameter is defined to evaluate a “kinking” effect in roads. Extraction of different road shapes with an acceptable precision in both urban and rural environments proves the efficiency of the algorithm in yielding complete road networks.

[Termes IGN] TaïwanRésumé : (auteur) Determining the geometry of an exposed gravel-bed surface is important in understanding river flow characteristics. This study presents a method of generating a digital elevation model (DEM) of exposed gravel-bed surfaces using two different scales of images of a riverine environment. The small scale DEM covers an area of 4·5 m × 4·5 m and serves as the reference base, whereas several large scale DEMs provide highly detailed elevation information along the site diagonals. The equipment includes a consumer-grade camera and is light and easy to set up in the field. Highly automated procedures using several off-the-shelf packages ease the burden of generating DEMs of the gravel-bed surface, reducing the technological obstacles for other disciplines. This study evaluates the accuracy of the proposed method at three study sites with different grain sizes along the Hou-Jue River in southern Taiwan. The elevation accuracy obtained by the proposed method was validated by a total station and achieved a root mean square error of 2·9 to 4·3 mm.
