Abstract (en)

[origin: WO2014016001A1] A device and a method for determining three-dimensional surface coordinates of an object by means of optical colour triangulation are proposed, wherein all lines (3) of a colour fringe pattern (1) in each case have a width (BR) set in such a way that, in a recorded image (7) of the line (3), all contrast maxima (CMax), of all spectral components of a line (3) are equal to a minimum contrast value (CMin). Proceeding from an invariable smallest width of a pattern line (3a) with a spectral component of highest contrast, further lines (3) can be correspondingly widened. The invention is particularly advantageously suitable for a 3D measurement for biological tissue.
