Camera parameters are the parameters used in a camera model to describe the mathematical relationship between the 3d coordinates of a point in the scene from which the light comes from and the 2d coordinates of its projection onto the image plane. Ideally, we assume the pixels are square, but in the real world, they can be rectangular with. And.
