example

[0025] Experimental standard material: 1 yuan coin with a diameter of 25mm.

[0026] A one-yuan coin is placed on the belt for scanning and shooting, and its diameter measurement value is 79 pixels; the pixel length and width are both 0.4mm, that is, the measurement value is 79*0.4mm=31.6mm.

[0027] Actual diameter: 25mm

[0028] X-ray imaging system magnification = image width / object width = 31.6mm / 25mm = 1.3

[0029]Experimental biological material: mature rice. The mature paddy rice of one fringe is placed in the device entrance of the present invention, operates according to the above-mentioned method, finally obtains that the grain number of this rice fringe is 172, and the average grain area of ​​rice grain, average grain length, average grain width are respectively 97.94, 17.94, 6.81 (in pixels), the corresponding actual values ​​are

[0030] Actual average grain area=97.94*0.4*0.4 / (1.3*1.3)=9.3mm 2 ,

[0031] Actual average grain length = 17.94*0.4 / 1.3 = 5.5mm,...

Abstract

The invention relates to an automatic measurement device of rice parameters, and a method thereof. The device is controlled by a preset computer; a single-plant threshing instrument is used for threshing rice spikes; the grain falls onto a belt through the single-plant threshing instrument and a straight groove type interface; the running belt is used for separating the grain; an X-ray imaging system is used for shooting a X-ray transmission map; a computer is used for processing the images so as to acquire the parameters of the rice. The automatic measurement device adopts the X-ray imaging method; the digital image processing technology is used for processing the shot images so as to acquire the parameters of the rice; the threshed grain needs no decladding treatment; the threshing and the parameter extraction are integrated into one system; and the automatic measurement device has the advantages of non-destructive installation, accurate and reliable measurement results, simple operation, and so on.

Description

technical field [0001] The invention belongs to machine vision detection technology, and in particular relates to an automatic rice parameter measurement device and method. The device can automatically measure the parameters of rice grains on a panicle of rice, including grain number, grain length, grain width, grain area, etc., and is suitable for the field of digital agriculture. Background technique [0002] Rice is one of the main food crops in my country, and it is used in rice variety tests, demonstrations, extensions and high-yield cultivation tests. It is necessary to test and investigate rice varieties to determine their utilization value. In most cases, indoor test species are mainly manually measured by scientific researchers. With the rapid development of computer technology, the research and application of machine vision technology are becoming more and more extensive. Compared with manual inspection technology, visual inspection technology has the advantages...
