风云三号D星真彩色影像合成方法研究及应用
|
摘要
多光谱遥感数据真彩色合成影像具有处理速度快、不依赖其他遥感产品、易于理解判读等特点,其在气象、生态环境、减灾等领域具有不可替代的作用。本文以风云三号D卫星MERSI-Ⅱ传感器数据为例,经过大气校正和非线性拉伸等方法合成了真彩色影像。应用真彩色影像对沙尘、蓝藻、火灾和台风等事件进行监测分析,分析结果表明真彩色影像可以在上述事件中起到识别相关事件的影响范围、事件的发展变化情况等信息的作用。
True color composite image using multi-spectral remote sensing data is fast in processing speed,independent of other remote sensing products,and easy to interpret. It plays an irreplaceable role in fields such as meteorology,ecological environment,and disaster reduction. In this study,the data from Medium Resolution Spectrum Imager-Ⅱ( MERSI-Ⅱ) onboard Fengyun-3 D( FY-3 D) are utilized to composite true color image after atmospheric correction and nonlinear stretch. True color image can detect disasters such as sand and dust,blue-green algae,fire,and typhoon. Relevant results indicate that true color image can identify the affected area,development and changes,and some other useful information in the above-mentioned events.
