A 3D Pattern for Post Estimation for Object Capture - Wang, Grimm, Pless (2003) (Correct)
.... Other work that explicitly uses ellipses as part of planar patterns for calibration and pose estimation include Rothwell [6] who calculates a set of specific points using tangent lines and intersection, Song [7] who uses an iterative approach that requires a corresponding pair of conics, and Ji [3] who considers ellipses as one of many geometric primitives (the others are points and lines) and gives a least squares solution for arbitrary sets of matched primitives. A planar pattern s 2D features can be di#cult to extract from oblique camera angles (below 30 degrees) This means that one ....

....Song [18] who uses an iterative approach and requires a corresponding pair of conics [16] and Kaminski [12] who reconstructs the conic and the calibration parameters. Most related to our solution is the single image direct methods of computing planar pose. Much of this work is summarized in [11], which integrates previous work into a unified geometric framework which uses combinations of point and line features. Spatially aware devices: Non traditional user interfaces, such as Graspable [6] Tangible [10] or Manipulable [8] interfaces, have been shown to be better than the traditional ....

....from points, lines and curves has been extensively studied. Estimation based only on point correspondences from four [25] and more points is introduced in [13, 19] Haralick, et.al. 20] provides a review of many 3 point techniques with a careful analysis of their stability. Qiang, et.al. [39] develops an analytic least squares technique for pose estimation from points, lines and ellipse circle pairs. These methods all assume a known correspondence between geometry and image features, which often requires extensive user involvement. Several techniques have been developed for automatic ....

As this optimization is typically prone to a small number of local minima, we run it from multiple initial positions. A detailed treatment of pose estimation from circle ellipse pairs can be found in [39]. Since this system with 10 equations and 6 unknowns is overdetermined, each solution returns an error that can be used to weed out most bad correspondences immediately. Otherwise, we use this initial guess for the pose to find a small set (typically less than 3) of candidate correspondences for ....
