[Termes IGN] triangulation (topologie)Résumé : (Auteur) This paper presents a general strategy for 3D reconstruction of complex architectural scenes. This approach makes use of both laser data (range and retro-diffusion) and image data, and of their great complementarity. The proposed approach starts with pose estimation between the two data sets. This part is largely automated by means of correlation of fine feature points and linear primitives. The second part deals with segmentation of the scene. Here, each element of the scene must be detected. This can be fulfilled in two ways. The first one is semi-automatic extraction of the objects where user interaction is used to initialize the object localisation, the second one is fully automatic segmentation, driven by image and 3D data. Then, each object needs to be reconstructed. We consider a large range of objects since we can describe planar surfaces, general geometric primitives and generalised cylinders. When these models do not fit with the surface, that is to say on complex parts, triangulation is performed. This leads to two potential reconstruction tools: one similar to laser data editing software, with more efficient object selection and object boundary estimation, the other would perform automatic reconstruction, which would be followed by a verification procedure. The advantage of this approach, compared to existing techniques, is to reduce dramatically reconstruction time, without having any hard limitation on the set of shapes that can be obtained.

[Termes IGN] visualisation 3DRésumé : (Auteur) Airbome laser scanner technique provides a 3D perception of the terrestrial topography, including true ground and objects belonging either to vegetated areas or to human made features. The high intrinsic accuracy and regularity of airborne laser sensors makes highly conceivable the extraction of semantic information related to the recorded 3D-points. In this respect, a new algorithm has been developed in order to classify the initial cloud of points into ground/non ground earth points and generale accurate Digital Terrain Models (DTMs) on a regular grid. Our approach is based on a multiple pass classification process. An estimation of the ground is performed within overlapping neighborhood and laser points are classified with regard to this ground estimation. The algorithm moves toward the neighbor where the average altitude is the lowest. We then compare the vicinity of the terrain with the estimated ground and apply a linear correction. As it goes along, points are filtered many times until we vote for the final label. The estimated ground surface is then the input of an energy minimization algorithm (ICM) which consider laser points as a set of attractors. The final DTM will be a trade off between internal properties and its closeness to ground laser points. The resolution may be fine enough to proceed relevant micro relief analysis especially in a rural environment.

[Termes IGN] orthorectificationRésumé : (Auteur) SPOT 4 stereo data from two different orbits with B/H 0.83 of the area in South-East Poland with denivelations reaching 550 m was elaborated in IGiK. 12 GCP.s and 15 ICP.s taken from 1: 10 000 topographic maps and orbital data have been used for orientation with the use of Image Station Multisensor Triangulation SPOT. The accuracy achieved on GCP.s: RMS X = 2.2 m, RMS Y = 2.3 m, RMS Z = 1.1 m; and on independent check points (ICP.s) RMS X = 5.0 m, RMS Y = 2.9 m, RMS Z = 4.7 m. DTM has been generated automatically with the use of MATCH-T Inpho software and filtered with in-house software. DTM prepared on the basis of SPOT stereo data has been checked against reference data - DTM generated from aerial photographs in scale 1:26 000. The accuracy of DTM generated with SPOT 5 HRS within the HRS Scientific Assessment program (HRS-SAP) of ISPRS and CNES on site 9 Chiemsee (Germany) is also presented. Geomatica OrthoEngine of PCI has been used for orientation and DTM generation.

[Termes IGN] reconstruction 3D du bâtiRésumé : (Auteur) During the past decade, the automatic generation of 3D city models has been a constant topic of research for several universities and cartographic or photogrammetric institutes. These 3D city models have a great potential for many applications, there is a real demand for. The costs of data acquisition are still high. The choice of the input data for a framework is one of the most important key to the production line. The object of this paper is to study the potential and impact of different input data contexts. Therefore, we use an operational building extraction framework able to reconstruct buildings from aerial images and cadastral maps. Concerning the reconstruction modules the buildings can be extracted with fully automatic methods as a prismatic extraction or a model driven algorithm. Although this framework has been initially developed for an aerial image context, laser Digital Surface Model (DSM) and satellite images context has been studied. So, on several datasets, 3D city models are produced through this approach with aerial or satellite images with different resolutions (from 80 cm to 20 cm) or laser scanning DSM. An external 3D reference allows to evaluate from qualitative and quantitative points of view. The results obtained from each input data context are compared. Finally, for each input data context, we discuss the different possibilities of 3D city models specifications, especially for the level of details, geometric accuracy and exhaustiveness.
