Book excerpt: This book constitutes the refereed proceedings of the Dynamic 3D Imaging Workshop, Dyn3D 2009, held in Jena, Germany as an associated event of DAGM 2009, the main international conference of the "Deutsche Arbeitsgemeinschaft für Mustererkennung". The 13 revised full papers presented were carefully reviewed and selected for inclusion in the book. The papers cover a range of topics of current interest: fundamentals of ToF- sensors, algorithms and data fusion and applications of dynamic 3D scene analysis. This book is aimed at researchers interested in novel approaches in the field of real-time range imaging.
