Title:

GARLIC CROP RECOGNITION METHOD BASED ON COUPLED ACTIVE/PASSIVE REMOTE SENSING IMAGES ON CLOUD PLATFORM

Document Type and Number:

WIPO Patent Application WO/2022/057319

Kind Code:

A1

Abstract:

Proposed is a garlic crop recognition method based on coupled active/passive remote sensing images on a cloud platform. The steps are as follows: first, obtaining an optical satellite remote sensing image on the basis of phenological characteristics of garlic, and, by combining geographic coordinate information of garlic, constructing a decision tree model for garlic optical image recognition, thereby obtaining a garlic optical distribution map; then, obtaining radar image features of garlic and winter wheat on the basis of a synthetic-aperture radar satellite, and, by combining geographic coordinate information of the garlic, constructing a decision tree model for garlic radar image recognition, thereby obtaining a garlic radar distribution map; finally, coupling the garlic optical distribution map and the garlic radar distribution map, that is, selecting the intersection of the two distribution maps, and completing garlic remote sensing recognition mapping. The present invention comprehensively utilizes the advantages of optical satellite images and synthetic-aperture radar images, solves the technical problem in which garlic and winter wheat are difficult to distinguish, and achieves accurate and automatic recognition by means of the remote sensing of the distribution of garlic on a large regional scale of a geographic space based on a cloud platform.
