What is Pinhole Camera Model

The pinhole camera model is a mathematical representation of the relationship between the coordinates of a point in three-dimensional space and its projection onto the picture plane of an ideal pinhole camera. In this model, the camera aperture is portrayed as a point, and there are no lenses employed to concentrate light. By way of illustration, the model does not take into account geometric distortions or the blurring of unfocused objects that can be brought about by lenses and apertures of a finite size. The fact that the majority of practical cameras only have discrete picture coordinates is another thing that is not taken into consideration. Because of this, the pinhole camera model can only be utilized as a first-order approximation of the mapping from a three-dimensional scene to a two-dimensional graphical representation. Its validity is contingent on the quality of the camera, and in general, it diminishes from the center of the image to the edges as the effects of lens distortion rise.
