An object of the present invention is to provide an estimation method capable of estimating the type and transparency of a crushed piece. A method of irradiating light from above on a shredded piece placed on a horizontal plane to obtain an upper color image, a step of masking the upper color image to create an upper mask image, and an upper mask image And obtaining the RGB component and HSV component information of the dark pixel in the upper mask image, the ratio of pixels in which the average value of the R component and the average value of the V component are equal, and the average value of the S component The process of discriminating between the outer skin and the cocoon, and the attribution of each cocoon type consisting of yellow cocoon, tea candy, and black cocoon to the cocoon pixel of the upper mask image in which the crushed pieces identified as cocoon are reflected The type of the crushed piece, including the step of calculating the degree and determining the crushed piece in the type of crease having the highest degree of attribution, and the step of estimating the transparency of the crushed piece identified as jaundice using fuzzy inference and A method of estimating the brightness.
