摘要：
A method has been developed for measuring the shapes of 3-D objects whose surfaces have regions of different reflectance. The 3-D coordinates of the object sections are obtained by triangulation with a light-section method, using a slit light source and a CCD camera. A CCD camera with an expanded dynamic range is employed to reduce the influence of reflection from uneven surfaces. The CCD camera expands the dynamic range by combining multiple images captured at different shutter speeds. A trial 3-D shape measurement system has been produced using our method. The effectiveness of the method was confirmed experimentally. (C) 1998 Scripta Technica, Elects Eng. Jpn, 126(2): 40-47, 1999.
