[Termes IGN] reconstruction 3D du bâtiRésumé : (Auteur) A novel approach by integrating multi-view aerial imagery and lidar data is proposed to reconstruct 3D building models with accurate geometric position and fine details. First, a new algorithm is introduced for determination of principal orientations of a building, thus benefiting to improve the correctness and robustness of boundary segment extraction in aerial imagery. A new dynamic selection strategy based on lidar point density analysis and K-means clustering is then proposed to identify boundary segments from non-boundary segments. Second, 3D boundary segments are determined by incorporating lidar data and the 2D segments extracted from multi-view imagery. Finally, a new strategy for 3D building model reconstruction including automatic recovery of lost boundaries and robust reconstruction of rooftop patches is introduced. The experimental results indicate that the proposed approach can provide high quality 3D models with high-correctness, high-completeness, and good geometric accuracy.

[Termes IGN] zone urbaineRésumé : (Auteur) Orthorectification of satellite data is one of the most important pre-processing steps for application oriented evaluations and for image data input into Geographic Information Systems. Although high- and very high-resolution optical data can be rectified without ground control points (GCPs) using an underlying digital elevation model (DEM) to positional root mean square errors (RMSEs) between 3 m and several hundred meters (depending on the satellite), there is still need for ground control with higher precision to reach lower RMSE values for the orthoimages. The very high geometric accuracy of geocoded data of the TerraSAR-X satellite has been shown in several investigations. This is due to the fact that the SAR antenna measures distances which are mainly dependent on the terrain height and the position of the satellite. The latter can be measured with high precision, whereas the satellite attitude need not be known exactly. If the used DEM is of high accuracy, the resulting geocoded SAR data are very precise in their geolocation. This precision can be exploited to improve the orientation knowledge and thereby the geometric accuracy of the rectified optical satellite data. The challenge is to match two kinds of image data, which exhibit very different geometric and radiometric properties. Simple correlation techniques do not work and the goal is to develop a robust method which works even for urban areas, including radar shadows, layover and foreshortening effects. First the optical data have to be rectified with the available interior and exterior orientation data or using rational polynomial coefficients (RPCs). From this approximation, the technique used is the measurement of small identical areas in the optical and radar images by automatic image matching, using a newly developed adapted mutual information procedure followed by an estimation of correction terms for the exterior orientation or the RPC coefficients. The matching areas are selected randomly from a regular grid covering the whole imagery. By adjustment calculations, parameters from falsely matched areas can be eliminated and optimal improvement parameters are found. The original optical data are orthorectified again using the delivered metadata together with these corrections and the available DEM. As proof of method the orthorectified data from IKONOS and ALOS-PRISM sensors are compared with conventional ground control information from high-precision orthoimage maps of the German Cartographic Survey. The results show that this method is robust, even for urban areas. Although the resulting RMSE values are in the order of 2–6 m, the advantage is that this result can be reached even for optical sensors which do not exhibit low RMSE values without using manual GCP measurements.

[Termes IGN] test de performanceRésumé : (Auteur) Within this paper, results of a test on the evaluation of the most recent photogrammetric digital airborne camera systems are presented. This project was initiated by the German Society of Photogrammetry, Remote Sensing and Geoinformation (DGPF), based on data from 12 different digital sensor systems flown in a well-controlled test site. The main topics of the evaluation phase are the analysis of geometric accuracy and sensor calibration, the radiometric performance including on-site radiometric calibration and multi-spectral land classifications, the performance of photogrammetric Digital Surface Model (dsm) generation, and the potential of manual stereoplotting from digital images. Within this paper, only results obtained at the Institute of Photogrammetry (iff), Universitaet Stuttgart will be presented, comprehensively proving the high performance of digital camera systems and processing. The IFF served as the pilot center and additionally concentrated on the investigation of camera geometry and the image based generation of height data.

[Termes IGN] précision géométrique (imagerie)Résumé : (Auteur) The Alpa 12 Metric, a medium-format digital camera system, is presented along with an accuracy assessment in accordance with VDI/VDE 2634 (2002). The camera combines the advantages of a modular medium-format camera system with high accuracy in object space. Camera calibration revealed a maximum length measurement error of 0·043 mm for a lens with mechanically fixed focusing distance and 0·063 mm for a lens where the focusing ring was taped during image acquisition. Only in the latter case did the maximum length measuring error improve, yielding 0·050 mm when calibrated with image-variant parameters of interior orientation. A bias towards positive length measurement errors indicated that the set-up for calibration could be improved and that even better accuracy in object space may be accomplished. The Alpa 12 camera system provides several unique features including lenses with fixed displacement of the principal point for terrestrial and other special applications, rigid tilt adaptors for Scheimpflug correction, shim kits for the fine adjustment of flange focal distance as well as the possibility of mounting a monochrome digital medium-format back, sensitive to visible and near infrared light. The camera is well suited for terrestrial applications requiring high accuracy and/or large pixel counts.
