Remote sensing identification method of desert plants using object-oriented multi-source information fusion

Abstract

The present invention relates to a desert plant remote sensing recognition method using object-oriented multi-source information fusion, which adopts the following five units: a large-area multi-source information mosaic unit, an object-oriented image segmentation unit, a multi-source information fusion unit, an interpretation rule formulation unit and Desert plant identification unit; In view of the fact that the existing technology does not consider the sparse distribution of desert plants, the growth spectrum information is weak, and it is easily affected by diffuse reflection, the characteristics of mixed pixels and the phenomenon of different spectra of the same object, developed an object-oriented multi-source The remote sensing identification method of desert plants based on information fusion can solve the problems of inability to accurately identify desert plant types and spatial and temporal distribution in the fields of ecological restoration, climate change, biodiversity, gene development, poverty eradication, etc. Non-profit organizations, enterprises and even the government provide technical support and provide data analysis basis for the development, construction and management of the desert vegetation industry in arid areas.

Description

technical field [0001] The invention relates to computer digital image processing and pattern recognition, and the application field of remote sensing, in particular to a desert plant remote sensing recognition method utilizing object-oriented multi-source information fusion. Background technique [0002] Desert plants refer to sparse vegetation dominated by xeric semi-arbors, semi-shrubs, small semi-shrubs and shrubs, and are important vegetation landscapes in subtropical and temperate arid regions. It is mainly distributed in the vast Gobi desert starting from North Africa, going east through West Asia, Central Asia, and South Asia to northwest my country and Mongolia. In addition, it also has a certain area of ​​​​distribution in the deserts of North and South America and Australia. Desert vegetation is an indicator of local ecological environment evolution and climate change, and is also an important part of global land surface processes. It is related to the energy conv...
