  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. 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 ...

  5. Epipolar geometry - Wikipedia

    en.wikipedia.org/wiki/Epipolar_geometry

    The epipolar geometry then describes the relation between the two resulting views. Epipolar geometry is the geometry of stereo vision. When two cameras view a 3D scene from two distinct positions, there are a number of geometric relations between the 3D points and their projections onto the 2D images that lead to constraints between the image ...

  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 ...

    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 ...

  8. 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.
