Abstract
A device and a method for determining three dimensional surface coordinates of an object by means of optical color triangulation are proposed, wherein all lines of a color fringe pattern in each case have a width (BR) set in such a way that, in a recorded image of the line, all contrast maxima (CMax), of all spectral components of a line are equal to a minimum contrast value (CMin) is provided. Proceeding from an invariable smallest width of a pattern line with a spectral component of highest contrast, further lines can be correspondingly widened. The invention is particularly advantageously suitable for a 3D measurement for biological tissue.
