  • Patent number: 5680216
    Abstract: In a device for raster-stereographic measurement of body surfaces, preferably of irregularly shaped objects, in which a raster pattern having a plurality of raster lines is projected onto the surface according to the method of raster stereography by a raster projector and a line image which is distorted by the surface shape is recorded by means of a camera which forms a stereo base with the raster projector, the raster pattern having periodically recurring, particularly emphasized lines, where the order number of the lines can be deduced from the regular recurrence of these particularly emphasized lines, the raster pattern which is projected onto the surface contains locally modulated raster lines, wherein at least adjacent raster lines are clearly distinguished from one another.
