根据航空遥感实验获取的TIMS图象,利用计算机图象处理主成分分析和去相关等方法,并依据TIMS成象机制,提取出花岗岩、斜长片麻岩以及粘土化、硅化等蚀变岩岩性和丰富的断层信息,结合金矿化带光谱特征,圈出金矿化异常区,同时TIMS图象也显示了该地区北北东向金矿成矿主断层控制金矿化的规律,现有分析成果表明热红外多光谱扫描仪所获得的图象数据在岩性和金矿化带的识别上,以及增强断层信息方面有较好效果.
According to the TIMS image acquired by aerial remote sensing experiment, using the method of principal component analysis and decorrelation of computer image processing, and according to the TIMS imaging mechanism, we extracted the granite, plagioclase gneiss and the alteration rocks such as clay and silicification Sex and abundance of fault information, combined with the spectral characteristics of the gold belt, gold out of the abnormal zone, while the TIMS image also shows that the North-East gold mine in the main metallogenetic control of the law of gold mineralization, and now Some analysis results show that the thermal infrared multi-spectral scanner image data obtained in the identification of lithology and gold mineralization zone, and to enhance the fault information has a good effect.
