Abstract
In this paper we develop the best homogeneous matrix trans- formation to fit two streams of dynamic six-degree-of-freedom (6DOF) data for evaluating perception systems using ground truth. In particular, we compare object position and orien- tation results from a 6DOF laser tracker that we consider to be ground truth with results from a real-time visual servoing system from the Purdue Robot Vision Lab. A problem that arises when comparing these two data streams is that they are not necessarily in the same coordinate system. There- fore, a method to transform one coordinate system to the other is needed. We solve this problem by developing an op- timization problem that minimizes the space between each coordinate system. In other words, we construct a rotation and translation which best transforms one coordinate space to the other.Proceedings Title
