| Abstract: | Using the automated grid method with grids projection and sub pixel techniques, automatic measurement of 3 D shape is successfully carried out. A new method for grids segmentation, Whole field Threshold Function Method, which increases the segmenting speed and qualities of the segmented grids, is proposed. In order to automatically and successfully recognize the large deformed or incomplete grids array, a new method, Neighboring Grids Indexed Recognition, is presented. The automated grid method for profilometry is tested by experiments on standard flat and cylindrical surfaces and some of the results are presented in this paper. |
