Calibration of lens distortion by structured-light scanning

This paper describes a new method to automatically calibrate lens distortion of wide-angle lenses. We project structured-light patterns using a flat display to generate a map between the display and the image coordinate systems. This approach has two advantages. First, it is easier to take correspondences of image and marker (display) coordinates around the edge of a camera image than using a usual marker, e.g. a checker board. Second, since we can easily construct a dense map, a simple linear interpolation is enough to create an undistorted image. Our method is not restricted by the distortion parameters because it directly generates the map. We have evaluated the accuracy of our method and the error becomes smaller than results by parameter fitting.
