Example Embodiment
[0045] Example 1:
[0046] Experimental research on image recognition and conduction of soil moisture.
[0047] 1. Image acquisition test
[0048] The test soil was taken from the silty clay of the Yunyuan Experimental Base of Hunan Agricultural University, and 1.5 kg of soil was selected and placed in a blast oven to dry at 105°C. The saturated moisture content of the tested silty clay was 54%. Set the soil moisture content to 0%, 10%, 20%, 30%, 40%, 50%, 60%. The setting method is to select 100g of dry soil and add 60g of water to stir evenly, and gradually dry, weighing every 10 minutes The quality changes and the image is collected when the set moisture content is reached. The images are all taken under the same lighting conditions and at a fixed location. The color of soil with different moisture content is like figure 2 Shown.
[0049] 2. Image analysis test
[0050] Analyze the color stability part of the collected image by intercepting the test soil, the size of the intercep...
