WebA projective camera model describes the mathematics of transforming a world point into an image point. This is done by assuming a pinhole model of a camera. Coupled with a distortion model which characterizes the deviation from the pinhole model, it is possible to model most cameras in this method*. A projective camera model only considers the ...
