We present a set of graphical user interface elements, called widgets, for 2-dimensional visual codes. The proposed widgets are suitable for printing on paper as well as showing o...
The paper presents an extended hand-eye calibration approach that, in contrast to the standard method, does not require a calibration pattern for determining camera position and or...
This paper presents an approach for applying a dual quaternion hand– eye calibration algorithm on an endoscopic surgery robot. Special focus is on robustness, since the error of ...
We present an approach for estimating the relative transformations between fragments of a broken cylindrical structure in 3d. To solve this problem, we first measure the orientatio...
