Camera calibration is an important issue in computer vision. In this paper, we propose an improved camera auto-calibration algorithm from sequential images based on VP (vanishing point) and EKF (extended Kalman filter) to determine camera intrinsic parameters. This is the first vanishing point-based auto-calibration algorithm, which only uses a sequence of monocular images as input without any other...
Simultaneous pose and correspondence estimation problem is used to determine the pose of a 3D object from a single 2D image when corresponding relation is unknown between 3D object points and 2D image points. The problem arises in many areas of computer vision and some algorithms have been presented. However, all the state-of-art algorithms rely on appropriate initialization and the correct solution...
