If the images to be rectified are taken from camera pairs without geometric distortion, this calculation can easily be made with a linear transformation.X & Y rotation puts the images on the same plane, scaling makes the image frames be the same size and Z rotation & skew adjustments make the image pixel rows directly line up [citation needed].
The measurement is taken from the film plane to the subject and effectively the film plane is the point in the camera where the film sits in the gate. [1] Light measurements can also be taken at the film plane. [2] Due to Petzval field curvature, the film plane upon which a lens
The plane which is spanned by axes X1 and X2 is the front side of the camera, or principal plane. An image plane, where the 3D world is projected through the aperture of the camera. The image plane is parallel to axes X1 and X2 and is located at distance f {\displaystyle f} from the origin O in the negative direction of the X3 axis, where f is ...
That line (e R –x R) in the right camera is called an epipolar line. Symmetrically, the line O R –X is seen by the right camera as a point and is seen as epipolar line e L –x L by the left camera. An epipolar line is a function of the position of point X in the 3D space, i.e. as X varies, a set
Light enters a dark box through a small hole and creates an inverted image on the wall opposite the hole. [2]The fundamental technology of most photography, whether digital or analog, is the camera obscura effect and its ability to transform of a three dimensional scene into a two dimensional image.
is the rotation matrix by which b is rotated in relation to a; t is the translation vector from a to b; n and d are the normal vector of the plane and the distance from origin to the plane respectively. K a and K b are the cameras' intrinsic parameter matrices. The figure shows camera b looking at the plane at distance d.

For example, when α is the ground plane and β is the horizon plane, then the vanishing line of α is the horizon line β ∩ π. To put it simply, the vanishing line of some plane, say α , is obtained by the intersection of the image plane with another plane, say β , parallel to the plane of interest ( α ), passing through the camera center.
