Claim Text:
1. An apparatus for determining three-dimensional surface coordinates of an object by means of optical color triangulation, comprising: a projector device for illuminating the object with a set color fringe pattern, wherein the color fringe pattern extends along an axis and consists of lines which are perpendicular thereto and which have a different selection of spectral components of the projected light in each case with respect to adjacent lines; an acquisition device arranged in a known relative position with respect to the projector device and serving for recording an image of the object onto which the color fringe pattern was projected once; a computer device for calculating the three-dimensional surface coordinates by means of identifying the selection of the spectral components of a respective line and acquiring a respective transition of two lines adjoining one another, wherein for all lines, by means of the projector device, the width of a respective projected line is set wherein, in the recorded image of the line, all contrast maxima (Cmax) of all spectral components of said line are equal to a minimum contrast value (Cmin).
