Abstract

In this paper, we present a method for calibrating intrinsic and extrinsic camera parameters. This algorithm can easily be modified by other users to suit their particular calibration needs, without requiring a high precision calibration target or complicated linear algebra. The algorithm uses controlled motions and a single light source to simulate calibration targets in convenient 3D locations. These convenient calibration targets enable us to simplify the calibration algorithm and gather dense data for lens distortion. Dense data makes the distortion correction more accurate than traditional low-order polynomial fits, and allows us to calibrate wide-angle lenses (> 70° field of view).
