Abstract

The invention relates to the technical field of image processing, in particular to a remote sensing image processing method and system for land resource management, and the method comprises the steps: marking ground features on a remote sensing image, and determining sample points of initial sample classification of the ground features; acquiring a ground feature spectrum curve corresponding to the ground feature, and performing false color synthesis on wave bands corresponding to a wave crest point, a wave trough point and a maximum curvature point in the ground feature spectrum curve to obtain a false color image; obtaining a false color wave band combination, corresponding to each wave band of the false color image, in the RGB channel, and according to the change consistency of sample points of the same kind in different false color wave band combinations, performing reclassification on the sample points to obtain intermediate sample points; determining representative test vectors according to the intermediate sample points; and taking the representative test vector as a parameter of a PPI algorithm to determine a final sample point, and performing final sample classification on the remote sensing image according to the final sample point to obtain a classification result, so that the method improves the classification precision, and reduces the occurrence of wrong classification and missing classification.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a remote sensing image processing method and system for land resource management. Background technique [0002] The management of land resources generally collects remote sensing images through satellites, and reflects land coverage and utilization, environmental monitoring, agricultural production estimation, and forest fires based on remote sensing images. Therefore, the identification of land types in remote sensing images is an essential part. Only Only by accurately classifying land types can the corresponding land resources be managed accurately from remote sensing images. [0003] With the development of computer technology, the method of artificial visual recognition of ground features has been gradually eliminated. Today's methods of ground feature recognition often use the method of supervised classification, that is, first select samples of different types of ...
