Abstract:
A device for generating a photometric stereo image and a color image of an object which is moved at a predetermined relative speed relative to the device. The device includes a lighting area and a lighting arrangement which is oriented to the lighting area. The lighting arrangement cyclically emits a lighting sequence in the lighting area. The lighting sequence has at least four lighting pulses each of which have a wavelength range and a lighting direction. At least three of the at least four lighting pulses have a different wavelength range, and at least two of the at least four lighting pulses have a different lighting direction and a same wavelength range.
