The invention discloses a method for identifying
embryo ends of
brown rice grains, a method for separating the
brown rice grains from whole
brown rice grains and a separation device, and relates to the field of brown
rice grain whole
embryo extraction. The invention aims to solve the problem that the germ concentration of brown rice grains is low due to the fact that tip sections of two rice grains cannot be separated in an existing germ-remaining rice
processing mode. According to the recognition method, on the basis of the image of the brown rice grains transmitted by the
light source, the end with the
embryo is recognized through differences of the gray levels of the two ends of the image, the brightness and / or geometric morphology of the HSV space and the like, and then separation of the end is achieved. According to the device, when brown rice grains pass through a light-transmitting piece in the sliding process of a rice falling plate, an image
recognition system takes a picture and recognizes that brown
rice grain germs are located at the left end or the right end, the positions of the germs are determined according to the image
recognition system, and a pneumatic unit is controlled to blow / suck the brown rice grains with germ tips into inner grooves in the two ends of a rice falling groove in the length direction; the cutter
assembly located on the rice falling plate cuts off the brown rice, and the germ tip section and the non-germ section respectively fall off and are collected in the separation opening of the rice supporting plate.
