METHOD FOR COMPENSATING A CHROMATIC ABERRATION, A METHOD AND DEVICE FOR MEASURING A 3D SHAPE USING THE SAME, CAPABLE OF COMPENSATING A CHROMATIC ABERRATION CAUSED BY A COLOR DIFFERENCE BETWEEN A MEASURING OBJECT FORMED IN A SUBSTRATE AND THE SUBSTRATE

摘要

PURPOSE: A method for compensating a chromatic aberration, a method and device for measuring a 3D shape using the same are provided to eliminate a shadow area by forming a first lighting unit and second lighting unit on locations facing each other.;CONSTITUTION: A method for compensating a chromatic aberration is as follows. A change amount of a phase reference of red lights, a change amount of a phase reference of green lights, and a change amount of a phase reference of blue lights are obtained(S101). An average intensity of the red lights, an average intensity of the green lights, and an average intensity of the blue lights are obtained(S102). A face off-set is obtained by using the change amount of the phase reference of the red lights and green lights and blue lights and the average intensity of the red lights and green lights and blue lights(S103).;COPYRIGHT KIPO 2012
