| titleOfInvention | A kind of crop canopy nitrogen monitoring method and system |
| abstract | The crop canopy nitrogen monitoring method and system provided by the invention include: synchronously acquiring RGB images and multi-spectral images of the area to be monitored; determining the vegetation coverage of the area to be monitored according to the RGB images; Spectral vegetation index; use vegetation coverage and spectral vegetation index to calculate the coverage adjustment spectral index, build a crop canopy nitrogen remote sensing monitoring model based on the coverage adjustment spectral index, and generate a pixel-scale crop canopy nitrogen content space in the area to be monitored. Distribution. The crop canopy nitrogen monitoring method and system provided by the invention make full use of the advantages of high spatial resolution of RGB images and the advantages of high spectral resolution of multispectral images, can effectively eliminate the inhibitory effect of soil background, and significantly improve crops The accuracy of remote sensing estimation of nitrogen enables spatial monitoring of crop nitrogen remote sensing at the pixel scale, which can provide spatial information technical support for precise variable fertilization decisions in the field. |
