In real applications, there is often the need of estimating the intrinsic and extrinsic parameters of a camera directly from the images of natural scenes or working scenarios. When there are only several feature points can be determined, the results of current calibration methods are very unstable. In this paper, a geometrical method is presented for estimating a restricted camera. It can estimate f even when only one feature point is valid. Experiments show that it has good robustness and reliability, and it is tolerant to multiple error sources.
