Abstract

Abstract: A way to extract grassland fire information is given in NOAA/AVHRR image without channel 3(Thermal Infrared Band) after analysing the information distribution of principal component analysis. Grassland fine information is highlighted with Lab color model based on sufficient utilization of the principal components.

Key words: Grassland fire, Information extraction, NOAA/AVHRR image, Principal component analysis

摘要： 在主成分分析的信息分配过程,提出在没有NOAA/AVHRR3波段数据的情况下,提取草原火信息的方法。在充分利用各主成分信息的基础上,利用Lab色采模型有效地突出了草原火信息。
