WebThe matrix of intrinsic parameters does not depend on the scene viewed. So, once estimated, it can be re-used as long as the focal length is fixed (in case of a zoom lens). Thus, if an image from the camera is scaled by a factor, all of these parameters need to be scaled (multiplied/divided, respectively) by the same factor.

They include information like focal length ( \(f_x,f_y\)) and optical centers ( \(c_x, c_y\)). The focal length and optical centers can be used to create a camera matrix, which can be used to remove distortion due to the lenses of a specific camera.
