Abstract

The invention relates to the technical field of forest resource measurement, and discloses a tropical forest resource measurement method based on a satellite remote sensing technology, which is characterized by comprising the following steps of: 1) acquiring remote sensing image information based on tropical forest resources to be measured through the satellite remote sensing technology, and preprocessing the acquired remote sensing image information. According to the tropical forest resource measurement method based on the satellite remote sensing technology, the vegetation region is extracted through the fixed matching threshold index, the forest texture structure primitives are constructed in combination with multiple texture features to extract forest vegetation in the vegetation region, the working efficiency and investigation quality of tropical forest resource investigation can be greatly improved, and meanwhile, the problem of low reset rate of a ground detection sample plot, a sample line and a sample tree in a traditional survey method is solved, the real-time performance, accuracy, reliability and rapid updating capability of monitoring data can be effectively improved, and tropical forest resources can be more effectively measured and analyzed.

Description

technical field [0001] The invention relates to the technical field of forest resources measurement, in particular to a method for measuring tropical forest resources based on satellite remote sensing technology. Background technique [0002] Satellite remote sensing technology is a comprehensive science and technology, which integrates the achievements of space, electronics, optics, computer communication and geosciences. It is the main component of 3S (RS, GIS, GPS) technology. Satellite remote sensing is based on artificial satellites. Platform, according to the relative position of the satellite as a platform and the earth, satellites can be divided into geostationary satellites (such as geostationary meteorological satellites and geostationary communication satellites) and polar orbiting satellites. [0003] The traditional classification of tropical forest vegetation through manual field surveys cannot meet the target requirements of fast and effective detection of for...
