Desert plant remote sensing identification method using object-oriented multi-source information fusion

Abstract

The invention relates to a desert plant remote sensing identification method using object-oriented multi-source information fusion. The method comprises the following five units: a large-area multi-source information inlay unit, an object-oriented image segmentation unit, a multi-source information fusion unit, an interpretation rule making unit and a desert plant identification unit. In the prior art, the following conditions that desert plant distribution is sparse; growth spectrum information is weak; desert plants are easily influenced by diffuse reflection; and phenomena of a mixed pixel and a same object with different spectrums are remarkable are not considered. Aiming at the above problems, the desert plant remote sensing identification method using the object-oriented multi-source information fusion is researched and developed so that problems that desert plant types and space-time distribution can not be accurately identified in fields of ecological remediation, a climatic change, a biological diversity, genetic development, poverty elimination and the like can be solved. A technical support is provided for a correlation research mechanism, a commonweal organization, an enterprise and a government. A data analysis basis is provided for exploitation, construction and management of a desert plant industry in an arid region.

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...
