Embodiment 1

[0030] Such as figure 1 Shown is a flowchart of a method for detecting chalky rice provided by an embodiment of the present invention. The method includes the following steps:

[0031] Step S101, preprocessing the RGB image of the rice grain sample to determine whether the rice grain in the RGB image of the rice grain sample is chalky rice.

[0032] In the embodiment of the present invention, the detection system first preprocesses the RGB image of the rice sample, and determines whether the rice in the RGB image of the rice sample is chalky rice through the preprocessing. The preprocessing the RGB image of the rice sample to determine whether the rice in the RGB image of the rice sample is chalky rice includes:

[0033] 1. Convert the RGB image of the rice grain sample into a grayscale image, and obtain a threshold for adaptive segmentation in the grayscale image.

[0034] In the embodiment of the present invention, the method for obtaining the threshold value of adaptive segmentati...

Embodiment 2

[0060] Such as figure 2 Shown is the structure diagram of the chalky rice detection system provided by the embodiment of the present invention. For ease of description, only the parts related to the embodiment of the present invention are shown, including:

[0061] The preprocessing unit 201 is configured to preprocess the RGB image of the rice grain sample to determine whether the rice grain in the RGB image of the rice grain sample is chalky rice.

[0062] In the embodiment of the present invention, the detection system first preprocesses the RGB image of the rice sample, and determines whether the rice in the RGB image of the rice sample is chalky rice through the preprocessing. The preprocessing by the preprocessing unit 201 includes:

[0063] 1. Convert the RGB image of the rice grain sample into a grayscale image, and obtain a threshold for adaptive segmentation in the grayscale image.

[0064] In the embodiment of the present invention, the method for obtaining the threshold v...

Abstract

The invention is applicable to the field of data processing, and provides a detection method of chalky rice. The method comprises the following steps: pretreating a rice grain sample RGB image, and judging whether rice grains in the rice grain sample RGB image are chalky rice; if yes, judging whether the placement mode of the rice grain sample leads to false detection; and calculating the chalky rice grain rate and chalky degree of the chalky rice according to the preset formula. According to the embodiment of the invention, the rice grain sample RGB image is pretreated so as to judge whether the rice grains in the rice grain sample RGB image are chalky rice, and if the judgment result is yes, then whether the placement mode of the rice grain sample leads to false detection is judged, and the chalky grain rate and the chalky degree are obtained according to the preset formula, so that the detection of the chalky rice is more accurate.

Description

Technical field [0001] The invention belongs to the field of data processing, and particularly relates to a detection method and a detection system for chalky rice. Background technique [0002] my country is the largest rice producer in the world. The rice planting area accounts for about 22.8% of the world's total planting area, and the total output accounts for 35% of the world's total output. Rice is the largest food crop in my country. The planting area of ​​rice accounts for 30% of the total area of ​​food crops, while rice accounts for 40% of the total grain output. More than two-thirds of the population in the country use rice as the main food, and the human body needs 60%-80% of the calories, 50%-70% of the protein, some inorganic salts and vitamin B, mainly from rice. The rice industry has a pivotal strategic position in my country. [0003] The appearance of rice is a very important indicator of rice quality, and it is also an important factor affecting rice market pr...
