Abstract

In this paper, we apply two fundamental approaches toward evaluating a static, vision based, six-degree-of-freedom (6DoF) pose determination system that measures the position and orientation of a part. The first approach uses groundtruth carefully obtained from a laser tracker and the second approach doesn't use any external groundtruth. The evaluation procedure focuses on characterizing both the system's accuracy and precision as well as the effect of object viewpoints. For the groundtruth method, we first use a laser tracker for system calibration and then compare the calibrated output with the surveyed pose. In the method without external groundtruth, we evaluate the effect of viewpoint factors on the system's performance.
