2. Pinhole camera model - Wikipedia

   en.wikipedia.org/wiki/Pinhole_camera_model

   The geometry of a pinhole camera. Note: the x 1 x 2 x 3 coordinate system in the figure is left-handed, that is the direction of the OZ axis is in reverse to the system the reader may be used to. The geometry related to the mapping of a pinhole camera is illustrated in the figure. The figure contains the following basic objects:

3. Pinhole camera - Wikipedia

   en.wikipedia.org/wiki/Pinhole_camera

   A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole)—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.

4. Epipolar geometry - Wikipedia

   en.wikipedia.org/wiki/Epipolar_geometry

   Epipolar geometry. Each camera captures a 2D image of the 3D world. This conversion from 3D to 2D is referred to as a perspective projection and is described by the pinhole camera model. It is common to model this projection operation by rays that emanate from the camera, passing through its focal center.

5. Triangulation (computer vision) - Wikipedia

   en.wikipedia.org/wiki/Triangulation_(computer...

   In the following, it is assumed that triangulation is made on corresponding image points from two views generated by pinhole cameras. The ideal case of epipolar geometry. A 3D point x is projected onto two camera images through lines (green) which intersect with each camera's focal point, O 1 and O 2. The resulting image points are y 1 and y 2.

6. Camera matrix - Wikipedia

   en.wikipedia.org/wiki/Camera_matrix

   The camera matrix is sometimes referred to as a canonical form. So far all points in the 3D world have been represented in a camera centered coordinate system, that is, a coordinate system which has its origin at the camera center (the location of the pinhole of a pinhole camera). In practice however, the 3D points may be represented in terms ...

7. Collinearity equation - Wikipedia

   en.wikipedia.org/wiki/Collinearity_equation

   Light beams passing through the pinhole of a pinhole camera. The collinearity equations are a set of two equations, used in photogrammetry and computer stereo vision, to relate coordinates in a sensor plane (in two dimensions) to object coordinates (in three dimensions).

   Making a pinhole camera at home is easy. You'll only need a few supplies: cardboard, white paper, and a push pin. 1. Start by taking your piece of cardboard and making a tiny hole directly in the ...

9. Homography (computer vision) - Wikipedia

   en.wikipedia.org/wiki/Homography_(computer_vision)

   Geometrical setup for homography: stereo cameras O 1 and O 2 both pointed at X in epipolar geometry. Drawing from Neue Konstruktionen der Perspektive und Photogrammetrie by Hermann Guido Hauck (1845 — 1905) In the field of computer vision, any two images of the same planar surface in space are related by a homography (assuming a pinhole ...
