| titleOfInvention | Remote sensing retrieval method and system of nitrogen content in fruit tree canopy based on image shadow removal |
| abstract | The present application discloses a method and system for remote sensing inversion of nitrogen content in fruit tree canopy based on image shadow removal, obtaining multispectral images of orchard drones and preprocessing; The shadow of fruit tree canopy in spectral images; establish a remote sensing inversion model to perform remote sensing inversion of nitrogen content in fruit tree canopy. Since UAV vegetation canopy multispectral images usually contain shadows, these shadows weaken the spectral information of vegetation and reduce the inversion accuracy of canopy nitrogen content. The inversion model of canopy nitrogen content before and after shadow removal based on shadow index not only avoids the complexity of separating shadow and non-shadow areas, but also effectively removes fruit tree canopy shadow, and the model inversion accuracy is higher and more stable after shadow removal. . |
