Plane-based self-calibration aims at the computation of camera intrinsic parameters from homographies relating multiple views of the same unknown planar scene. This paper proposes a straightforward geometric statement of plane-based self-calibration, through the concept of metric rectification of images. A set of constraints is derived …

The concept of spontaneous electric field (Es) in polar structures is crucial for understanding the physical and chemical properties of compound semiconductors and improving their performanes. However, this concept has not been widely accepted so far. Here, we show the first observation of rectifica …
Image rectification is an important stage of digital image processing for three-dimensional (3D) coordinate measurements performed using stereoscopic technique. Rectification minimizes image distortions and radically reduces the calculation time necessary for stereo matching. Calibration of prism-based stereoscopic optical systems …
Rectification requires a projective transformation or homography of the image plane. This homography is associated with the circular points, a pair of Euclidean invariant points imaged on the vanishing line of the plane. It can be computed from scene constraints. Specifically, we use parallel lines, lines at known orientations, pairs of unknown ...
The rectification plane does not correspond to the intended evaluation plane. Single-Image or Mono Image Measurement Measurement principle. The measuring ray of an image measurement is intersected with a 3D plane. This plane is defined in advance using at least 3 points. If a more than 3 point are used to define the plane, a …

The rectifying transformation Up: Epipolar Rectification Previous: Camera model and epipolar Rectification of camera matrices We assume that the stereo rig is calibrated, i.e., the PPMs and are known. The idea behind rectification is to define two new PPMs and obtained by rotating the old ones around their optical centers until focal planes becomes …
This paper introduces a new strategy for plane rectification in sequences of images, based on the Expectation-Maximization (EM) algorithm. Our approach is able to compute simultaneously the parameters of the dominant vanishing point in the image plane and the most significant lines passing through it. It is based on a novel definition of the likelihood …
