Book Description
Robot calibration is the process of enhancing the accuracy of a robot by modifying its control software. This book provides a comprehensive treatment of the theory and implementation of robot calibration using computer vision technology. It is the only book to cover the entire process of vision-based robot calibration, including kinematic modeling, camera calibration, pose measurement, error parameter identification, and compensation. The book starts with an overview of available techniques for robot calibration, with an emphasis on vision-based techniques. It then describes various robot-camera systems. Since cameras are used as major measuring devices, camera calibration techniques are reviewed. Camera-Aided Robot Calibration studies the properties of kinematic modeling techniques that are suitable for robot calibration. It summarizes the well-known Denavit-Hartenberg (D-H) modeling convention and indicates the drawbacks of the D-H model for robot calibration. The book develops the Complete and Parametrically Continuous (CPC) model and the modified CPC model, that overcome the D-H model singularities. The error models based on these robot kinematic modeling conventions are presented. No other book available addresses the important, practical issue of hand/eye calibration. This book summarizes current research developments and demonstrates the pros and cons of various approaches in this area. The book discusses in detail the final stage of robot calibration - accuracy compensation - using the identified kinematic error parameters. It offers accuracy compensation algorithms, including the intuitive task-point redefinition and inverse-Jacobian algorithms and more advanced algorithms based on optimal control theory, which are particularly attractive for highly redundant manipulators. Camera-Aided Robot Calibration defines performance indices that are designed for off-line, optimal selection of measurement configurations. It then describes three approaches: closed-form, gradient-based, and statistical optimization. The included case study presents experimental results that were obtained by calibrating common industrial robots. Different stages of operation are detailed, illustrating the applicability of the suggested techniques for robot calibration. Appendices provide readers with preliminary materials for easier comprehension of the subject matter. Camera-Aided Robot Calibration is a must-have reference for researchers and practicing engineers-the only one with all the information!

Book Description
A calibration procedure is generally an operation to determine a relationship between an output and an input of an instrument or an essential value of a measuring object in a measuring system. In other words, calibration is a comparison of a measuring device against a standard instrument of higher accuracy. In measuring fields, the calibration is clearly confirmed in the traceability system. The traceability is defined as the property of a result of a measurement whereby it can be related to strictly defined standards, in general, nationally or internationally recognised, through an unbroken chain of comparisons. Namely, all calibrations are strictly defined to be performed traceable to a nationally or internationally recognised standard in a measuring field. The term calibration is used not only in measuring fields but also in meteorology, chemistry and economics. Also, in these fields the term calibration is used as an operation to adjust and/or compensate a measuring system, and a method for accurately determining the relational expression between an input/output of an instrument using suitable standards, for example, an appropriate global optimisation method.However, compared to the measuring field, in these other research areas the calibration seems to be defined in a less systematic way, possibly due to the different nature of these disciplines. In this volume, calibration is defined in the above-mentioned broad sense of the term, and the topics for discussion are broad and abundant. The standard of calibration as a method which is confirmed systematically in the measurement field has been developing also in other disciplines. They have many research issues, but constitute a promising area of research.
