Wolfgang Förstner – författare

This textbook offers a statistical view on the geometry of multiple view analysis, required for camera calibration and orientation and for geometric scene reconstruction based on geometric image features. The authors have backgrounds in geodesy and also long experience with development and research in computer vision, and this is the first book to present a joint approach from the converging fields of photogrammetry and computer vision. Part I of the book provides an introduction to estimation theory, covering aspects such as Bayesian estimation, variance components, and sequential estimation, with a focus on the statistically sound diagnostics of estimation results essential in vision metrology. Part II provides tools for 2D and 3D geometric reasoning using projective geometry. This includes oriented projective geometry and tools for statistically optimal estimation and test of geometric entities and transformations and their rela­tions, tools that are useful also in the context of uncertain reasoning in point clouds. Part III is de­voted to modelling the geometry of single and multiple cameras, addressing calibration and orienta­tion, including statistical evaluation and reconstruction of corresponding scene features and surfaces based on geometric image features. The authors provide algorithms for various geometric computa­tion problems in vision metrology, together with mathematical justifications and statistical analysis, thus enabling thorough evaluations. The chapters are self-contained with numerous figures and exer­cises, and they are supported by an appendix that explains the basic mathematical notation and a de­tailed index.The book can serve as the basis for undergraduate and graduate courses in photogrammetry, com­puter vision, and computer graphics. It is also appropriate for researchers, engineers, and software developers in the photogrammetry and GIS industries, particularly those engaged with statistically based geometric computer vision methods.

Die DAGM '99 steht unter dem Thema "Interpretation natürlicher Szenen: Von der medizinischen Bildverarbeitung bis zur Fernerkundung". Dieses Motto greift aktuelle Entwicklungen in der Mustererkennung auf, intelligente Datenanalyse für große Datensätze zu betreiben und damit der Wissensgesellschaft neuartige Analysewerkzeuge für natürliche Szenen, aber auch für Data Mining zur Verfügung zu stellen.Im Tagungsband finden sich sowohl neue Entwicklungen auf dem Gebiet der Grundlagenforschung als auch interessante Anwendungen aus allen Bereichen der Mustererkennung wieder, wobei neben der Sprachverarbeitung vor allem Beiträge zu statistischen Verfahren, zur Analyse von Bildfolgen und zur Rekonstruktion der 3D-Geometrie aus Bildern dominieren.
