| Abstract: | This paper presents a new method to measure the 3D shape of an obj ect by the technique of proj ection of Ronchi grating and the subsequent moire phase-shifting to restore the image.When a Ronchi grating is proj ected onto the surface of an obj ect, the grating is perturbed according to the topography, the moire and the moire phase-shifting then automatically produced by the digital-image processing technique and the 3D shape of the object is restored. This technique has been verified by experiments, proved to be correct and having a good pre cision after processing. This method may be implemented easily and may get over several kinds of systematic errors; besides, it has good interference-resistance ability, high precision and automaticity. |
