| titleOfInvention | A Rapid Determination Method of Soil Water Content Based on Image Processing Technology |
| abstract | The invention provides a method for rapid determination of soil water content based on image processing technology, comprising the following steps: water extraction and color development in soil, colloidal material sedimentation in soil and soil color removal, filtration, soil sample liquid to be tested, The sample was photographed, the image area was selected and binarized, and substituted into the soil water content standard curve to obtain the water content X of 1 g of soil sample, the water content of the soil sample (%)=X/m. The rapid determination method of soil water content based on image processing technology proposed in the present invention respectively prepares water content of 0%, 1%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40% Standard solution, gray-scale processing according to the image processing method, and draw the standard curve, it is concluded that the soil water content is more than 40%, which is not conducive to the growth of crops, and the crops cannot grow normally if the soil water content is less than 3%, and the saturated water content is 18.5% to 20%. ; And compared with traditional measurement methods, it is not only simple and fast. |
