Abstract

We have already reported the construction of a 3D shapes measuring system using a spatial modulator. The system is composed of an optical spatial modulator from which grating patterns are projected on the surface of the object, a CCD camera, and a computer. The patterns on the surface of the object were taken into a computer by the CCD camera, and the 3D coordinate of the surface of the object was calculated. Some techniques have been proposed to reduce the error of the measurement and improve the accuracy. In this paper, we note the problems on the measurements, and discuss further improvements of the system. The 3D shapes of the objects are displayed on a display. We bring the system to an automatic system which project patterns, capture the patterns on the surface, calculate the 3D coordinate, and show the 3D shapes on a display.
