A method of evaluating the uniformity of an illumination pattern of an automotive head lamp on a road surface is presented. The most critical area where the beam pattern uniformity can be identified is the high intensity region. In this area three parameters are used to evaluate beam pattern uniformity, correlation set, contrast level and relative intensity factor gradient. In a low intensity region of the illumination pattern, the same principle can be applied.
