Traditional methods for acquiring as-built information like manual measurements by tape and tacheometry are not only slow and cumbersome but most of the time they also fail to provide the amount of detail required. Many industrial facilities provide a limited personnel access because of the presence of radioactive, toxic or hazardous materials together with an unsafe working environment, which necessitates the use of non-contact measurement methods.
Traditional photogrammetry depends on point or line measurements from which it is very hard to get complete CAD models without extensive manual editing and refinement. Compared to photogrammetry laser scanning provides explicit and dense 3D measurements. There has been a rapid increase in the speed and accuracy of the laser scanners in the last decade, while their costs and sizes have been continuously shrinking. All modeling tools available on the market depend on heavy operator intervention for most of the modeling tasks. Although there are some semi-automatic tools like plane or cylinder growing even there the operator has to start the growing process for each primitive. Furthermore, the fitted surfaces must be manually edited by the operator to convert them to a CAD description.
This thesis presents new methods and techniques which can be used for automatic or efficient semiautomatic 3D modeling of existing industrial installations from point clouds and images. The goal is to use explicit 3D information from the point clouds to automatically detect the objects and structure present in the scene. The detected objects are then used as targets for model based registration, which can be automated by searching for object correspondences. To avoid manual editing the presented techniques use models from a catalogue of commonly found CAD objects as templates for model fitting. In the final fitting phase images are also included to improve the quality of parameter estimation.
Segmentation is a very important step that needs to be carried out as a pre cursor to object recognition and model fitting. We present a method for the segmentation of the point clouds, which avoids over-segmentation while partitioning the input data into mutually disjoint, smoothly connected regions. It uses a criterion based on a combination of surface normal similarity and spatial connectivity, which we call smoothness constraint. As we do not use surface curvature our algorithm is less sensitive to noise. Moreover, there are only a few parameters which can be adjusted to get a desired trade-off between under- and over-segmentation.
Segmentation is followed by a stage of object recognition based on a variation of the Hough transform for automatic plane and cylinder detection in the point clouds. For plane detection the Hough transform is three dimensional. For the cylinder detection the direct application of the Hough transform requires a 5D Hough space, which is quite impractical because of its space and computational complexity. To resolve this problem we present a two-step approach requiring a 2D and 3D Hough space. In the first step we detect strong hypotheses for the cylinder orientation. The second step estimates the remaining three parameters of the cylinder i.e. radius and position.
The problem of fitting models like planes, cylinders, spheres, cones, tori and CSG models to point clouds is very important for data reduction. For the fitting of CSG models, this thesis presents three different methods for approximating the orthogonal distance, which are compared based on speed and accuracy.
We also present methods for using modeled objects in individual scans as targets for registration. As the available geometrie structure is used, there is no need to place artificial targets. We present two different methods for this purpose called Indirect and Direct method. The Indirect method is a quick way to get approximate values while the Direct method is then used to refine the approximate solution. We also present techniques for automatically finding the corresponding objects for registration of scans. The presented techniques are based on constraint propagation which use the geometric information available from the previously made correspondence decision to filter out the possibilites for future correspondences.
Although point clouds are very important for the automation because of their explicit 3D information, images provide a complementary source of information as they contain well-defined edges of the bounded objects. We present methods for the fitting of CSG models to a combination of point clouds and images. We also present techniques for the specification of geometric constraints between sub-parts of a CSG tree and their inclusion in the model estimation process. A taxonomy of commonly encountered geometric constraints and their mathematical formulation is also given.
We hope that the techniques presented in this thesis will lead to an improvement in efficiency and quality of the models obtained for industrial installations from point clouds and images.Note de contenu : 1 Introduction

[Termes IGN] transformationIndex. décimale : 33.70 Photogrammétrie terrestre Résumé : (Auteur) [...] Unlike conventional photo techniques, the scanning measuring systems based on polar measuring principles introduced to geodetic surveying practice within the past few years are suitable for the very fast measurement of individual objects, structures and whole buildings. The objects to be measured must not be accessible for the few minutes of continuous data acquisition, as they should be in the case of photogrammetric recording techniques. The scanning instruments are able, however, to ensure data acquisition rates of over 1000 discrete points per second.
In addition to the introduction to the technology of scanning polar measuring systems, this work deals with the development of suitable algorithms for the acceleration of the measurement and evaluation process. In the context of the calibration of scanning polar measuring systems with tachymetric measuring principles, special aspects are considered in the sub-field of structured geometry data acquisition, and the difficulties in combining sets of data from individual instrument points of view.
The combination of the readings from different instrument points of view in a standard primary system can be seen as a time-consuming factor in the evaluation of data from scanning measuring systems. Through the use of the procedure described in this work a reduction of the required evaluation time can be reached. By an automated extraction of iso-levels from the point clouds and a subsequent automatic assignment of the identities using projective transformations, the resulting iso-levels can be inspected with respect to the linked systern instrument points of view. The additional marking and subsequent measurement of reference points can therefore be avoided.
The development of an appropriate calibration method for scanning polar measuring systems based on tachymetric measuring principles is a second central point of this work. Special attention is given in this work to the regulation of systematic deviations and the precision details of the various integrated sensors. A system calibration method based on an extension of existing calibration procedures is proposed. Building on the point connection algorithms, a calibration method is introduced. This uses iso-levels and the help of the adjustment algorithm to estimate calibration parameters, as well as the precision of the measuring instruments. In conclusion, the efficiency and bounds of the calibration approach are examined and evaluated using measurements from two different laser scanners.Numéro de notice : 13269 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Thèse étrangère Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=54949 Exemplaires(2)

In a steady shift from traditional 2D--GIS toward 3D-GIS, a great amount of accurate 3D city models have become necessary to be produced in a short period of time and provided widely on the market. The authors have developed a system for automatic generation of 3D city models, using laser profiler data, 2D digital map, and aerial image, which are processed by the software newly developed. MapCube, the 3D city models generated by the system, has already covered all major cities of Japan at the end of 2002. Applications for virtual reality (VR) that deal with accurate and photo-realistic 3D city models are becoming indispensable in many fields. However, there had been no VR viewer that can appropriately deal with a great amount of 3D city data in real time. In order to solve the problem the authors have developed a new VR viewer called Urban Viewer that can make best use of 3D city models, especially MapCube. VR applications used on display devices should provide easy interactive operation. The authors have developed a new type of VR display device with optical sensors called NEXTRAX, which users can operate as easily as touch-panel display, with more accuracy of operation and much more durability. NEXTRAX also provides simultaneous display of co-related information including 3D city model, 2D digital map and varieties of multimedia information.
