基于HJ卫星遥感数据的林果光谱特征分析
Analysis of Spectral Characteristics of Fruit Trees Based on HJ Satellite Remote Sensing Data
摘要
Abstract
[Objective] The purpose of this project was to analyze the differences between fruit trees, such as apples, pears, walnuts and jujubes and other surface features. Some experimental researches into these differences have been done based on HJ satellite data, thus providing a theoretical base for the extraction of fruit trees and the identification of species. [ Method] With field survey data in Aksu area and basing on the HJ satellite data, the difference was analyzed by spectral analysis method and normalized vegetation index (NDVI) time series data during the growth period and derivative transformation (d1 [ log( 1/Rλ) ] ) method. [ Result] (1) The difference between fruit trees and other surface features was significant in the image which was imaged in May; (2) By derivative transforming, the data, their imaged times were in April and November, which showed that walnut and jujube trees had some different characteristics from the other fruit trees, but there was not significant difference between apple and pear trees. [ Conclusion] (1) The fruit trees messages can be extracted accurately based on HJ satellite data; (2) Walnut and jujube trees can be identified by HJ - CCD data, but its rather difficult to identify apple and pear trees. So it need further study.关键词
