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 ...
Early pinhole camera. Light enters a dark box through a small hole and creates an inverted image on the wall opposite the hole. [8]The first known description of pinhole photography is found in the 1856 book The Stereoscope by Scottish inventor David Brewster, including the description of the idea as "a camera without lenses, and with only a pin-hole".
A tram photographed with a pinhole objective attached to the lens mount of a digital camera. Camera obscura principle pinhole objectives machined out of aluminium are commercially available. [87] As the luminosity of the image is very weak in the phenomenon, long exposure times or high sensitivity must be used in digital photography.
Camera resectioning is the process of estimating the parameters of a pinhole camera model approximating the camera that produced a given photograph or video; it determines which incoming light ray is associated with each pixel on the resulting image. Basically, the process determines the pose of the pinhole camera.

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:
