Embodiment 1

[0027] A rice quality detection method, comprising the following steps:

[0028] Step 1: Obtain a preset amount of rice to be tested, and remove impurities from the rice to be tested;

[0029] Step 2: Weigh the rice to be detected by the weighing device, and transmit the weighing data to the intelligent terminal;

[0030] Step 3: Carry out preheating treatment on the rice to be tested, and arrange the rice regularly on the testing board after the preheating treatment;

[0031] Step 4: A light source is installed at the bottom of the test board, and a camera is set above the test board. The light source transmits light through the rice grains, and the camera collects the image of the transmission image. The focal length and focus are fixed throughout the shooting process, and the camera’s exposure time, sensitivity, The aperture size is fixed;

[0032] Step 5: Preprocessing the collected rice grain transmission image;

[0033] Step 6: After analyzing and comparing the rice t...

Abstract

The invention relates to the technical field of rice quality detection, in particular to a rice quality detection method, which comprises the following steps: step 1, obtaining a preset number of to-be-detected rice, and performing impurity removal treatment on the to-be-detected rice; step 2, weighing the to-be-detected rice through a weighing device, and transmitting the weighing data to an intelligent terminal; step 3, preheating the to-be-detected rice, and regularly arranging the preheated rice on a detection plate; and step 4, arranging a light source at the bottom of the detection plate, arranging a camera above the detection plate, and transmitting the rice grains through light emitted by the light source. Various appearance quality indexes of the rice can be accurately and automatically detected, multi-parameter and batch automatic analysis can be carried out, all test image analysis results and data can be displayed and stored on a computer, the data are accurate and reliable, the results are stable, repeatability is high, the quality condition of the rice can be easily obtained through the detection method, and the information is visually displayed on the intelligent terminal.

Description

technical field [0001] The invention relates to the technical field of rice quality detection, in particular to a rice quality detection method. Background technique [0002] Rice is one of the staple foods of human beings. According to the analysis of modern nutrition, rice contains protein, fat, vitamin A, E and various minerals. In terms of varieties, rice can be divided into stem rice and glutinous rice. Rice contains 75% carbohydrates. %, protein 7%-8%, fat 1.3%-1.8%, and rich in B vitamins, etc. The carbohydrates in japonica rice are mainly starch, and the protein contained is mainly rice glutenin, followed by rice gelatin And globulin, the biological value of its protein and the proportion of amino acids are higher than those of cereal crops such as wheat, barley, millet, and corn, and its digestibility is 66.8%-83.1%. It is also a higher type of cereal protein. The rice quality detection method has long detection time, large human error, and cannot realize accurate ...
