This unique book explores the important issues in studying for active visual perception. The book´s eleven chapters draw on recent important work in robot vision over ten years, particularly in the use of new concepts. Implementation examples are provided with theoretical methods for testing in a real robot system. With these optimal sensor planning strategies, this book will give the robot vision system the adaptability needed in many practical applications.Active Vision Sensors.- Active Sensor Planning - the State-of-the-Art.- Sensing Constraints and Evaluation.- Model-Based Sensor Planning.- Planning for Freeform Surface Measurement.- Sensor Planning for Object Modeling.- Information Entropy Based Planning.- Model Prediction and Sensor Planning.- Integrating Planning with Active Illumination.
