Fuente: WIPO Agriculture Portada The invention provides a ginseng facility agriculture domain determination method, and relates to the technical field of remote sensing image information processing, the method comprises the followingsteps: detecting ginseng facility agriculture domain and building images in a collected training sample of a remote sensing image; carrying out graying processing on the images of the ginseng facility agriculture domain and the building in the training sample to obtain a grayed image of the ginseng facility agriculture domain and the building in the training sample; determining a segmentation threshold NDGI according to the ginseng facility agriculture domains in the plurality of groups of training samples and the gray-scale map of the building; performing threshold segmentation on the ginseng facility agriculture domain and the graying map of the building in the training sample by using the segmentation threshold NDGI to obtain a graying map of the ginseng facility agriculture domain. According to the method, the range of the facility agriculture domain of the ginseng is determined according to the gray scale map of the facility agriculture domain of the ginseng, the remote sensing image is systematically calculated and processed, the distribution range of the ginseng can be determined, and the effect of real-time yield monitoring can be achieved.
