We did experiments also with the six-parametric model p6 which contains only two parameters in the radially symmetric part. C. Backward Model Above we have described our forward camera model Pc. WebThe pinhole camera model. The pinhole camera model is a model of an ideal camera, that describes the mathematical relationship between the real world 3D object's coordinates and its 2D projection on the image plane. 1. Pinhole cameras were the very beginning of photography 2, and are used even today to explain basic photography to students.
