Embodiment 1

[0047] Sandalwood plants with different iron content have differences in the absorption and reflection of electromagnetic waves in different bands during the growth process, resulting in different colors inside the leaves and forming different colors on the surface of the leaves. Therefore, color images can be used to detect Sandalwood plant growth soil iron content.

[0048] Such as figure 1 As shown, the present embodiment provides a method for image determination of iron element content in sandalwood plant growth soil, comprising the following steps:

[0049] 1) Establish the estimation equation and determine the parameters of the equation:

[0050] Step 1.1, obtain sandalwood plant image sample with camera;

[0051] Step 1.2, obtain sandalwood tree species foreground image with SVM image segmentation method;

[0052] Step 1.3, obtaining the characteristic parameters of the foreground image;

[0053] Step 1.4, obtaining a soil sample and measuring the content of iron in...

Embodiment 2

[0103] Embodiment 1 takes the sandalwood plant as the object, and can also use the method of the present invention as an example to implement the method of the present invention to Huanghuali, Dalbergia Dalbergia, red sandalwood, etc., its step is the same as Example 1, just use Huanghuali, Dalbergia Dalbergia , Replace the sandalwood plant image with the red sandalwood plant image and change the model parameters.

Embodiment 3

[0105] The present embodiment provides a kind of image determination system of sandalwood plant growth soil iron content, comprising:

[0106] An image acquisition device for acquiring a plant foreground color image;

[0107] The image acquisition device can be a camera or any device with a camera;

[0108] A computing unit for obtaining image parameters from a color image of a plant;

[0109] The determining unit is used for determining the iron element content of soil by using the iron element content estimation model according to the image parameters.

[0110] For the working principle of each unit in this embodiment, refer to the description of Embodiment 1.

[0111] Image acquisition means include ordinary cameras.

[0112] According to the present invention, the menstruation of the iron element content in the sandalwood plant growth soil can be realized by ordinary cameras and computers. Therefore, the present invention does not need to add additional equipment to est...

Abstract

The invention provides an image determination method and system for determining the iron element content in sandalwood plant growth soil and belongs to the technical field of measurement and computers. The method comprises the following steps that a predicted equation is established, and equation parameters are determined; a soil sample is obtained, and the iron element content in the soil is determined; a plant sample is obtained; a support vector machine (SVM) image partition method is used for obtaining a sandalwood tree species foreground image; image parameters are obtained, and the relation about the images and the iron element content in the soil is obtained; the iron element content in the plant soil is predicted based on the relation. By adopting the image determination method, judgment on iron element lack of the sandalwood plant growth soil can be achieved through a common camera and a computer. Therefore, the iron element content of currently growing sandalwood plants can be estimated without additional devices, and the image determination method and system is especially suitable for nutrient diagnosis of precious species and operating management work of healthy growth.

Description

technical field [0001] The invention relates to an image determination method and system for the content of iron elements in sandalwood plant growth soil, and belongs to the field of measurement and computer technology. Background technique [0002] Mineral elements are important nutrients necessary for the growth of organisms, and directly participate in basic biological processes such as metabolism, growth and development of the body. Among the trace elements necessary for plant growth and development, iron is indispensable for the formation of chlorophyll, which plays an indispensable role in important plant life activities such as photosynthesis, respiration and chlorophyll synthesis. Although iron is abundant in soil, the iron element is mostly Fe 2+ It exists in the form of , and its solubility is extremely low in high pH and calcareous soils, which seriously affects its utilization efficiency. [0003] Plant iron deficiency and chlorosis has become a common concern ...
