In this paper we present a method for robustly and accurately estimating the rotation and translation between a camera and a 3-D object from point and line correspondences. First we devise an error function and second we show how to minimize this error function. The quadratic nature of this function is made possible by representing rotation and translation with a dual number quaternion. We provide a detailed account of the computational aspecis of a trust-region optimization method. This method compares favourably with Newton's method which has extensively been used to solve the problem at hand, with Faugeras-Toscani's linear method [3] for calibrating a camera. Finally we present some experimental results which demonstrate the robustness of our method with respect to image noise and matching errors
