ABSTRACT:
A device for optical measuring of grains for analysis of the quality of the grains, comprises a feeder which is arranged to feed at least one grain in a direction of transport, a light source which is arranged to illuminate the grain along a line, a detector which is arranged to detect reflection from the surfaces of the grain and an analyzer which is arranged to analyze the detected reflection in order to determine a height profile of the grain along the line and to determine three-dimensional surface topographical information on the grain based on a plurality of determined height profiles as the grain is transported. The device further comprises an arrangement used in generating a two-dimensional image and the analyzer is arranged to determine a quality of the grain based on the three-dimensional surface information and the two-dimensional image of the same grain.
