In this paper we present a pose estimation algorithm based on four
coplanar point correspondences. Given four coplanar points and their
corresponding image points under a perspective camera, plus the camera's
intrinsic matrix, the camera's rotation and translation relative
to the object plane is determined directly. In essence, the pose
estimation problem is converted to the calculation of a planar homography
between the object plane and the image plane. Experiments with both
synthetic data and real images verify the correctness of this algorithm.
