| Abstract: | A topographical system based on virtual compound grating for the measurement of 3 D object shapes has been proposed. The object shapes with sudden surface changes can be measured by projecting dual frequency compound grating. The system is suitable for measuring 3 D shapes of machine part, and the obtained results are satisfactory. |
