Zusammenfassung:A device (200) for optical measuring of grains for analysis of the quality of said grains, comprises a feeder (102) which is arranged to feed at least one grain (101b) in a direction of transport (107), a light source (105) which is arranged to illuminate said grain (101b) along a line, a detector (108) which is arranged to detect reflection (109) from the surfaces of said grain and an analyzer (111) which is arranged to analyze said detected reflection in order to determine a height profile of the grain along the line and to determine three-dimensional surface topographical information on said grain based on a plurality of determined height profiles as said grain is transported. The device (200) further comprises an arrangement (220) used in generating a two-dimensional image and the analyzer (111) is arranged to determine a quality of said grain based on the three-dimensional surface information and the two-dimensional image of the same grain.
