Abstract : A method for calibrating linear cameras is described. It is shown that the more classical 2-D camera calibration techniques are necessary but not sufficient for solving the linear-camera calibration problem. A model for linear cameras is proposed, and a two-step procedure is presented for estimating its parameters. A camera-centered coordinate frame is defined, and the extrinsic parameters of the camera are determined, that is, the rigid transformation between the calibrating coordinate frame and the camera frame. The accuracy of the calibration method was analyzed through an example application.
