Vision ray calibration is a new method which measures the vision ray for each pixel of e.g. a camera. The advantage of this method is that no description of the optical system with the help of polynoms is necessary. This allows for calibration of extrem optics and of calibrating optics which have high frequency distortions.
A fully automatic calibration unit for imaging optics is available which is based on the vision ray calibration technique.
As an alternative, VEW offers to calibrate customer imaging optics using the vision ray calibration.
