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.
Some of the effects that the pinhole camera model does not take into account can be compensated, for example by applying suitable coordinate transformations on the image coordinates; other effects are sufficiently small to be neglected if a high quality camera is used. This means that the pinhole camera model often can be used as a reasonable ...
A camera obscura (pl. camerae obscurae or camera obscuras; from Latin camera obscūra 'dark chamber') [1] is the natural phenomenon in which the rays of light passing through a small hole into a dark space form an image where they strike a surface, resulting in an inverted (upside down) and reversed (left to right) projection of the view outside.
A pinhole camera is a simple camera without a lens that projects the image of an object through a small hole or aperture. Light passes through the pinhole to cast an image of the object on the ...
The Great Picture in its pinhole camera hangar. Orthorectified negative (top) and positive (bottom) representations of the photograph, partially obscured by two people. As of 2011, The Great Picture (111 feet (34 m) wide and 32 feet (9.8 m) high) holds the Guinness World Record for the largest print photograph, and the camera with which it was made holds a record for being the world's largest.

The hangar-turned-camera recorded a panoramic image of what was on the other side of the door using the centuries-old principle of "camera obscura" or pinhole camera. An image of the former El Toro Marine Corps Air Station appeared upside down and flipped left to right on film after being projected through the tiny hole in the hangar's metal door.
As such, they initiate a range of emotions from dream anxiety and helplessness, to being captivated by a fantasy and the romantic aesthetic quality of her old-fashioned pinhole method. [4] Her pictures hark back to the nineteenth-century approach to fine-art photography known as Pictorialism and to the well-known amateur photographer Julia ...
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.
