| Abstract: | A rapid and high accurate new no-concoct optical technique, which can be usedto measure 3-D surface, is set up by 2-D digital image processing of the grating projectedon 3-D surface.The appliable software has been developed on a microcomputer. Anautomoble boby is analysed by this software. Meanwhile, a boundary technique ispresented in order to improve the accuracy of the measuring technique. |
