基于MODIS遥感影像的火点信息提取算法实现

The Implementation of Fire Point Information Extraction Algorithm Based on MODIS Remote Sensing Image

森林火灾是一种危害极大的自然灾害,如何快速、精确定位并监测其发生和变化,对减少经济损失、保护生态环境尤为重要。MODIS影像由于具有覆盖面积广、波段个数多和成像周期短等特点,早已被广泛应用于火灾预警和监测中,且取得了良好的效果。本文尝试利用MATLAB来实现自动化提取MODIS影像中火点信息,以期为防火工作人员获取火灾信息提供便利。

Forest fire is a natural disaster with great harm. How to locate and monitor its occurrence and change quickly and accurately is particularly important to reduce economic losses and protect the ecological environment.MODIS image has been widely used in fire warning and monitoring because of its wide coverage, large number of bands and short imaging period, and has achieved good results. This paper attempted to use MATLAB to automatically extract fire information from MODIS images, in order to facilitate fire protection workers to obtain fire information.
