| 成果简介 | NOVELTY - Invention relates to agriculture. Method involves taking a control sample of seeds, successively irradiating each seed with an X-ray beam, obtaining an X-ray pattern of the seeds. In addition, reference glassy and mealy seeds are used, which are compared by the value of the attenuation index of the inner part of the seed k, X-ray patterns of the reference sample seeds are obtained, and the following operations are performed for each seed: obtaining a digital image of the X-ray image, taking the brightness of the pixel of the positive X-ray image as the X-ray radiation intensity, measuring initial radiation flux as average brightness of image pixels not belonging to seed, unfolding image with its long side vertically, creating a geometric model of the cross section of the seed, formed by curves of the second order, describing the passage of X-rays, for each horizontal row of image pixels, the seed width is calculated as the number of pixels of the row, for each pixel of the horizontal row the attenuation of X-ray radiation intensity during its successive passage of the shell, inner part, shell is determined. Estimating the thickness of the shell, calculating the attenuation coefficient of the inner part of the seed k by solving a common system of equations, which includes all equations of each row for all horizontal rows of pixels of the inner part of the seed, and based on the results of comparing the signal attenuation values obtained for each seed of the control sample and the range of signal attenuation values in the reference seeds, the seeds are referred to as glassy at k in range of 0.0085 to 0.0089 or to mealy at k in range of 0.0061 to 0.0066. USE - Agriculture. ADVANTAGE - Method provides higher objectivity of control due to reduced effect of seed coat on an indicator characterizing grain quality. 1 cl, 2 dwg |
