METHOD FOR OPTICAL MEASUREMENT OF THE SHAPE OF A THREE-DIMENSIONAL OBJECT

摘要

The inventive method consists in illuminating an initial object in a first direction by a radiation which is spatially modulated according to a periodic law and recording the first image of said object in a second direction which is different from the first. The initial object being substituted by a location flat face, the second image is recorded. The initial object being additionally illuminated by a spatially homogenous radiation in the first direction and the third image thereof being recorded, the fourth binary image is formed with the aid of the third image. The fifth image coinciding with the first image in the white areas of the fourth image and with the second image in the black areas of the fourth image being synthesised, the fifth and second images are coprossesed in order to restore the surface shape of the initial three-dimensional object.
