摘要
根据热红外波段对地物热信息反映灵敏的特征 ,基于CBERS-1卫星红外多光谱扫描仪(IRMSS)所获得的2000年7月1日宁夏汝箕沟地区的图像数据 ,首先进行错位纠正、去条带、消除随机噪声等处理。通过对IRMSSB6、B7、B8、B9单波段的线性拉伸、指数变换、主成份分析 ,以及IRMSSB6、B7和B8、IRMSSB6、B7和B9的假彩色合成处理、波段运算等增强处理 ,有效地提取了由煤层自燃引起的地表热异常 ,以及煤堆、裸岩、居民区的热异常信息。通过分析对比 。
According to the fat that thermal band is sensitive to thermal information, and based on CBERS-1 IRMSS Data of Quqigou are on Nanning Municipality received on July 1, 2000, mismatch correction, de-striping and random noise processing are conducted on IRMSS image. Linear stretch, index conversion and main composition analysis were conducted on each band of IRMSS B6, B7, B8 and B9. Some enhancement processing including pseudo color processing and band calculation were carried out. The surface thermal anomaly information caused by coalfield self-combustion and thermal anomaly of coal pile, bare rock and residential area. After analyses and comparison, evaluation of coal fire information collection by IRMSS data was conducted.
