Rice parameter automatic measuring equipment and method

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...

Problems solved by technology

The feeding mechanism is composed of a funnel, a grain counting instrument, a feeding guide trough, a limit plate and a glass loading tray, so that the grains can fall onto the glass loading tray in a single and sequential manner, so as to avoid a large number of grains when collecting images sticking phenomenon, but this method of single drop processing is very slow

At the same time, due to the use of CCD to take pictures, only the rice after husking can be processed, and the rice grains are easily damaged during the husking process.
