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 japonica, red sandalwood, etc., and its steps are the same as in Example 1, but only use huanghuali, Dalbergia japonica , 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 determination 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 es...

Abstract
The invention discloses an image determining method and system for iron element content in sandalwood plant growth soil, belonging to the field of measurement and computer technology. Including the following steps to establish an estimation equation and determine the parameters of the equation: obtain a soil sample and determine the iron content in the soil; obtain a plant sample; obtain a foreground image of a sandalwood tree species with a support vector machine (SVM) image segmentation method; obtain image parameters and establish an image The relationship between soil iron content and soil iron content; according to this relationship, plant soil iron content can be predicted. According to the present invention, the determination of iron deficiency in the sandalwood plant growth soil can be realized through ordinary cameras and computers. Therefore, the present invention can estimate the iron content of the sandalwood plant’s current growth without adding additional equipment, which is extremely suitable. In the nutritional diagnosis of precious tree species sandalwood and the management 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 ...
