A new method for robotics camera calibration based on a linear computation and using a coplanar group of calibration points is presented in this paper. This new method suppresses the constraint presented by the RAC calibration model of having an incidence angle between the optical axis and the calibration plane of at least 30 degrees. The parameters are obtained based on a multi-step calculatio...

The developments in optical metrology and computer vision require more advanced camera models. Their geometric calibration is of essential importance. Usually, low-dimensional models are used, which however often have insufficient accuracy for the respective applications. A sophisticated approach uses generalized model. Here, each pixel described individually by its ray properties. Our efforts ...
