Embodiment 1
[0039] Embodiment 1 rice appearance quality analysis device
[0040] like Figure 1~2 As shown, the rice appearance quality analysis device includes a display 1, a scanner 2, a data processor and an arrangement device; image. The data processor can be selected Lenovo C560 microcomputer, the scanner can be selected Lenovo M7206W multifunctional machine and other models, the optical element is CIS, and the optical resolution is 600 × 1200dpi. The inside of the cover plate 21 of the scanner 2 is provided with a detachable Background plate 22; Described background plate 22 is black cardboard, makes the background of the rice image of scanning appear black, reduces image background interference; Background plate 22 is fixed on the inside of cover plate 21 by fixing device; Described fixing device is provided with at least 2 The fixing device is composed of a suction cup 24 and a draw-in groove 23 fixed on the sucker 24; the groove of the draw-in groove 23 is arranged in parallel ...
Embodiment 2
[0065] Embodiment 2 instrument method detects chalky rice quantity
[0066] The rice sample was measured using the rice appearance quality analyzer of Example 1. First place the orifice plate on a glass plate and fit tightly. Weigh a certain amount of rice (0-15g), put it evenly on the orifice plate, and gently shake the orifice plate and the glass plate until the rice particles are dispersed in different holes. After the rice is separated on the glass plate by the orifice plate, it is gently placed on the scanner, the orifice plate is removed, and the scanner cover with a black background is closed. Open the software on the computer to scan the rice samples. After scanning, save the scanned rice sample pictures to the designated folder; run the rice sample processing program to perform operations on the designated pictures.
Embodiment 3
[0069] Chalky rice quantity detection under different threshold intervals of embodiment 3
[0070] The chalky threshold is distinguished by the gray value, and the gray value of the chalky part is greater than the gray value of other parts. In order to accurately obtain the detection results of chalky rice grains, it is necessary to optimize the threshold of chalky detection. Select 6 groups of samples with the number of rice grains set in a gradient, so that the number of rice grains is 100, 200, 300, 400, and 500 (respectively recorded as sample 1 to sample 5). Normal rice and chalky rice were picked manually, and chalky rice was mixed into normal rice so that the chalky grain rates were 100%, 80%, 60%, 40%, 20%, and 0%, respectively. According to the above method, three parallels were set up for each group of samples under different chalkiness rates. Measure according to the method of embodiment 2, debug the threshold value of rice sample processing program step S7, measu...
