DEVICE FOR DISCRIMINATING BONE PART IN MEAT AND METHOD FOR DISCRIMINATING BONE PART IN MEAT

摘要

PROBLEM TO BE SOLVED: To enable a bone part in a meat cut surface to be automatically discriminated.;SOLUTION: A bone part discrimination device 10 for detecting a bone part in a meat cut surface comprises: a first imaging unit 16 for irradiating the cut surface with visible light to obtain a first image by reflection light of the visible light; a second imaging unit 22 for irradiating the cut surface with infrared light having wavelength of 1100 nm to 1700 nm to obtain a second image by reflection light of the infrared light; a first binarization processing unit for binarizing the first image on the basis of difference in luminance values of the reflection light among a dark-fleshed part, a bone part and a fat part in the cut surface and extracting an area of the fat part; a second binarization processing unit for binarizing the second image on the basis of difference in luminance values of the reflection light among the dark-fleshed part, the bone part and the fat part in the cut surface and extracting areas of the bone part and the fat part; and a bone part extraction unit for extracting the area of the bone part by subtracting the area of the fat part extracted by the first binarization processing unit from the areas of the fat part and the bone part extracted by the second binarization processing unit.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
