The pinhole camera model is the basic camera model used in computer vision. Its name originates from the concept of pinhole camera and it models perspective projections.


The pinhole model is the basic camera model used in computer vision. Its name stems from the concept of pinhole camera [ 1] (also related to the camera obscura [ 2]): usually, a closed box into which a single tiny hole is made with a pin, through which light may enter and hit a photosensitive surface inside the box (cf. Fig. 1). Pinhole cameras allow to take photographs of objects, which usually requires long exposure times due to the small aperture. The principles behind pinhole cameras and the camera obscura have been known, at least partially, since the fourth century BC [ 2].
