There is a leaf color leaf nitrogen content and the highly related. In addition, also related to the yield and eating quality of rice. The method of measuring leaf color, there is a method using a color scale and chlorophyll meter. However, both methods, Should a person conducting measurements fall within the farm. In addition, as a result by the measurement position is different. Color scale is a visually judged. For this reason, the color of the color scale under the influence of weather and illumination, appear in a different color. There is also when the artificial error occurs.
In the present study, to elucidate the relationship between the growth parameters showing the spectral measurement information and the state of growth of rice. The purpose of the study was to extract information about the growth diagnosed using spectral information acquired. More specifically, the field was divided the amount of fertilization in three stages, was measured using a hyperspectral camera, captures the surface spectroscopic information. In addition, to implement the growth and yield research study, including leaf color measurement by the visual at the same time. By comparing consider each result, think about a method of determining the leaf color by spectroscopic information.
And calculates the reflectance from the image data acquired by the hyperspectral camera. By using the reflectance, think about the method of determining the leaf color by multiple regression analysis and ordinal scale.
