An Improved Orthogonal Iterative Algorithm for Monocular Camera Pose Estimation

Camera Pose Estimation in Unknown Environments using a Sequence of Wide-Baseline Monocular Images

In this paper, a feature-based technique for the camera pose estimation in a sequence of wide-baseline images has been proposed. Camera pose estimation is an important issue in many computer vision and robotics applications, such as, augmented reality and visual SLAM. The proposed method can track captured images taken by hand-held camera in room-sized workspaces with maximum scene depth of 3-4...

Direct Pose Estimation with a Monocular Camera

We present a direct method to calculate a 6DoF pose change of a monocular camera for mobile navigation. The calculated pose is estimated up to a constant unknown scale parameter that is kept constant over the entire reconstruction process. This method allows a direct calculation of the metric position and rotation without any necessity to fuse the information in a probabilistic approach over lo...

An Efficient Iterative Pose Estimation Algorithm

An Eecient Iterative Pose Estimation Algorithm

We propose a novel model-based algorithm which nds the 3D pose of an object from an image by breaking down the estimation process into two linear processing stages, namely the depth approximation and the pose calculation. The depth approximation stage determines the new positions of the model point set in 3D space whereas the pose calculation step is a least-square estimation of the transformat...

3D Face pose estimation and tracking from a monocular camera

In this paper, we describe a new approach for estimating and tracking three-dimensional (3D) pose of a human face from the face images obtained from a single monocular view with full perspective projection. We assume that the shape of a 3D face can be approximated by an ellipse and that the aspect ratio of 3D face ellipse is given. Given a monocular image of a face, we ®rst perform an ellipse d...
