OPTICAL INSPECTION METHOD FOR CARBON FIBER REINFORCED PLASTIC COMPONENT

摘要

An embodiment of the present invention provides an optical inspection method for a carbon fiber reinforced plastic (CFRP) component, the method performing an inspection by maintaining a focal length with respect to the surface of an object to be inspected and enabling the optic axis of a photographing device to match the normal line of the surface of the object to be inspected. The optical inspection method for a carbon fiber reinforced plastic (CFRP) component according to an embodiment of the present invention comprises the steps of: (a) collecting shape data of the surface of an object to be inspected; (b) calculating a distance between the surface of the object to be inspected and a photographing device by means of the shape data of the surface of the object to be inspected, and calculating an angle between the optic axis of the photographing device and the normal line of the surface of the object to be inspected; (c) moving the photographing device so that the distance between the surface of the object to be inspected and the photographing device is equal to the focal length of the photographing device; and (d) adjusting the angle of the photographing device so that the optic axis of the photographing device matches the normal line of the surface of the object to be inspected.
