Forest resource measuring method based on satellite remote sensing technology

Abstract

The invention discloses a forest resource measuring method based on a satellite remote sensing technology. The method comprises that: remote sensing image information based on a forest resource to be measured is acquired via the satellite remote sensing technology, and the acquired remote sensing image information is preprocessed; a main parameter index of the forest resource to be measured is extracted on the basis of the preprocessing result of the remote sensing image information; multiple forest resource index numerical values in a remote sensing image are counted on the basis of the extracted main parameter index; a classification condition is selected according to the counting result, and a classification model supporting a vector machine is established; and the forest resource to be measured is classified by using an SVM classifier on the basis of the established the classification model supporting the vector machine. According to the forest resource measuring method based on the satellite remote sensing technology, defects in the prior art that measuring accuracy is low, coverage range is small and enforcement difficulty is high, etc. can be overcome so that advantages of being high in measuring accuracy, large in coverage range and low in enforcement difficulty can be realized.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for measuring forest resources based on satellite remote sensing technology. Background technique [0002] The modernization of forest resource management has prompted people to put forward higher requirements for the precision and fineness of forest resource management. Obtaining forest resource information by means of traditional actual sampling survey has low precision, and the sampling coverage and sampling quantity are very limited, which makes it difficult for the traditional forest resource assessment technology based on the extraction calculation method to meet the needs of modern forest resources. management needs. [0003] The use of remote sensing satellites to achieve accurate measurement of forest resources is a very promising forest resource management method at present. The use of satellite remote sensing technology can conduct comprehensive ana...
