Each intrinsic parameter describes a geometric property of the camera. Camera resectioning is the process of estimating the parameters of a pinhole camera model approximating the camera that produced a given photograph or video. The values fx and fy are the pixel focal length, and are identical for square pixels. Calibrate each camera independently (e.g., with matlab's camera calibration app) calibrate both cameras simultaneously (e.g., with matlab's stereo camera calibration app).

Usually, the pinhole camera parameters are represented in a 3 × 4 matrix called the camera matrix.this process is often called geometric camera calibration or simply camera calibration, although that term can also refer to. [c x c y] — optical center (the principal point), in pixels. Here, f_x and f_y are the focal lengths of the camera. Camera resectioning.
