| titleOfInvention | Regional organic matter content estimation method and device based on hyperspectral image |
| abstract | The application relates to a regional organic matter content estimation method and device based on hyperspectral images, soil organic matter data of certain places in a certain region and hyperspectral image data of the places are collected firstly, 9 one-dimensional spectrums and two-dimensional spectrums corresponding to the 9 one-dimensional spectrums are analyzed through data, a plurality of different models are respectively established according to the one-dimensional spectrums and/or the two-dimensional spectrums, fitting accuracy under four models of all the one-dimensional spectrums and/or the two-dimensional spectrums is compared, the spectrum with the highest accuracy and the used model are selected, and soil organic matter data of the remaining regions in the region are evaluated according to the selected spectrum and the model. Through the steps, the one-dimensional spectrum or two-dimensional spectrum type with the highest precision and the used model used for evaluation are screened out, and finally the estimation method with the highest precision for the organic matter content in the region can be obtained. |
