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
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].
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.
A 4-plane Multiplane background. The lowest plane, furthest from the camera, is only a rendering of a water surface. The plane above it contains (in addition to a cliff with a waterfall) a moving distortion glass, giving a ripple effect to the water. Note how the plane closest to the camera (dark tree in foreground at left) is strongly out of ...
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
Without tilt, the image plane (containing the film or image sensor), the lens plane, and the plane of focus are parallel, and are perpendicular to the lens axis; objects in sharp focus are all at the same distance from the camera. When the lens plane is tilted relative to the image plane, the plane of focus (PoF) is at an angle to the image ...

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
