Abstract

The invention discloses a method for extracting vegetation information from aerial photographs of cooperative remote sensing images, and relates to the technical field of image processing. An effective method for vegetation remote sensing monitoring is established by using aerial photographs and remote sensing images containing visible light bands to extract vegetation information. , to be applied to the plant identification research of destination aerial photos, to extract vegetation information quickly and relatively accurately.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for extracting vegetation information from aerial photographs of cooperative remote sensing images. Background technique [0002] In Southwest China, land degradation is the most serious erosion process. Karst is the most important natural landscape in Southwest my country, and its ecosystem is extremely fragile. At the same time, Southwest China is considered to be one of the three major karst regions in the world. Sufficient precipitation and hydrological processes in the region have led to serious geological hazards in the karst terrestrial ecosystem in Southwest my country. This process is called karst rocky desertification (KRD), and has attracted widespread attention from all parties. Southwest my country is the poorest region in China, and the sustainable development of agricultural products is greatly limited by rocky desertification. Although rocky de...
