| Abstract: | Hyperspectral data contain plenty of information about space, radiation and spectrum, which makes it feasible to quantificationally analyze the chemical concentration of earth surface. Studying the spectral characteristics of main biochemical components of plants with hyperspectral data, we can determine the concentration of various componets by use of certain algorithm. In this way we can at last supervise the growing status of plants. In this paper, stepwise multiple linear regression and spectrum derivative techniques are introduced to calculate the concentration of nitrogen, lignin and cellulose in plant. |
