The objective of the EuroSDR Building Extraction comparison was to evaluate the quality, accuracy, feasibility and economical aspects of semi automatic building extraction based on photogrammetric techniques with the emphasis on commercial and/or operative systems, semi-automatic and automatic building extraction techniques based on high density laser scanner data and semi-automatic and automatic building extraction techniques based on integration of laser scanner data and aerial images. The project consists of three test sites by the Finnish Geodetic Institute (FGI), namely Senaatti, Hermanni and Espoonlahti, and one test site by the Institut Geographique National (IGN), namely Amiens. For each test site following data was provided to the partners: aerial images, camera calibration and image orientation information, ground control point coordinates and jpg images of point locations (not for Amiens), laser scanner data and cadastral map vectors of selected buildings. Participants were requested to create vectors of 3D city models. 3D-models were obtained from 11 participants. The paper confirms with experiments that laser scanning is superior in deriving building heights, extracting planar roof faces and ridges of the roof, whereas photogrammetry and aerial images are superior in building outline and length determination.

[Termes IGN] reconstruction 3D du bâtiRésumé : (Auteur) Automatic 3D building reconstruction has becoming increasingly important for a number of applications. The reconstruction of buildings using only aerial images as data source has been proven to be a very difficult problem. The complexity of the reconstruction can be greatly reduced by combining the aerial images with other data sources. In this paper, we describe a 3D building reconstruction method that integrates the aerial image analysis with information from large-scale 2D Geographic Information System (GIS) databases and domain knowledge. By combining the images with GIS data, the specific strengths of both the images (high resolution, accuracy, and large-information content) and the GIS data (relatively simple interpretation) are exploited.

Since the introduction of the computer, and later the digital camera, research in photogrammetry aims at automation. This thesis reports on research on automation in architectural photogrammetry for efficient reconstruction of detailed building models from one or more possibly widely separated digital closerange images. This research is on the fringes of photogrammetry and computer vision. It treats topics frequently studied in computer vision in a photogrammetric way and offers new solutions. This approach is characterised by:
- Robust and direct solutions for approximate value computation Statistical testing of consistency of redundant information
- Integral leastsquares adjustment of all information for optimal parameter estimation Quality control by statistical testing and error propagation
- Semiautomatic processing, aiming at a reliable solution with a minimum of user interaction
- Precalibration of the camera's used
- Exploitation of generic knowledge of the object shape Use of image lines as the basic type of observations.
The research is presented in the form of a collection of papers published between 1997 and 2002. Furthermore, the methods described in the papers have also been applied to a reference set of images. The results of these experiments are presented in a separate chapter.
The demand for models of the built environment has increased due to the development of computer applications such as virtual and augmented reality, and computer games. In these applications the required accuracy of the models is not as high as in traditional applications of architectural photogrammetry, such as documentation of cultural heritage. Emphasis in research has shifted towards efficient production of computer models that show a high level of realism. [...]
The processing of images of the CIPA reference data set has demonstrated the capabilities and limitations of the developed methods for camera calibration, image orientation, and object reconstruction. Calibration of the camera was performed semiautomatically with five images of the reference data set. The results were compared with the camera information available from the reference data set. The maximum parameter difference was three times its standard deviation.
The two different methods for image orientation have been applied on four images taken at the corners of the building. The first one is based on the reconstruction of rectangles from a single image. Resulting orientations differ less than 4 degrees from the adjusted values derived in a bundle adjustment. With the second more automated method a correct approximate solution was obtained for all image pairs using two or three manually measured corresponding points. Full automation of relative orientation was not possible for all image pairs due to the repeating structures in the fagades and for imagery where image scale differences were large.
An object model was reconstructed based on a linephotogrammetric bundle adjustment of manual fine measurements in the same four images. Geometric object constraints made the reconstruction of occluded object points possible, improved regularity of the building model and strengthened the geometry of the network.
The research presented in this thesis contributes to the fields of photogrammetry and computer vision. However, emphasis is on photogrammetry where manual or semiautomatic measurement methods prevail and leastsquares adjustment is the tool commonly applied for parameter estimation. The developed linephotogrammetric bundle adjustment model that allows the incorporation of object shape knowledge is the main contribution to this field. Computer vision is generally more focussed on automation, single image processing, and the use of uncalibrated cameras. Therefore, the methods developed for vanishing point detection, used for image orientation and camera calibration, and the methods developed for reconstruction from a single image are primarily in the field of computer vision. In conclusion, this thesis contributes to bringing photogrammetry and computer vision closer together, which will be beneficial to both fields.Numéro de notice : 15053 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Thèse étrangère En ligne : https://www.ncgeo.nl/downloads/54VandenHeuvel.pdf Format de la ressource électronique : URL Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=55055 Réservation
