抄録

A non-contact method to measure 3-D shape of smooth glossy objects is proposed. This method uses a M-array coded light source to determine correspondence between a position on the light source and a point on an image of the surface of the glossy object which reflect light from the light source, and estimates the 3-D shape of the objects from the correspondence by fitting a plane localy. It requires less light source planes and smaller template for deciding the correspondence than conventional methods. The accuracy of measurement is also improved. The validity of the method is confirmed by experiments for plane mirror.
