提出了融合多光谱影像、全色影像、DEM等多元遥感信息的断裂特征增强方法,建立了以地形和水体的空间特征变化为基础的断裂解译标志,解译并发现桂西北巴马-马山断裂带和右江断裂带之间存在一条北西向展布、长约40km的新的右江次级活动断裂,结合野外地震地质调查进行了验证。多元遥感信息融合处理中,将KL变换、HIS变换、乘积变换、比值变换、小波变换等融合方法进行了全面比较,对融合后影像进行主分量分析,确定了乘积变换融合的影像增强方法和解译底图,显著突出了活动断裂特征。
A method for enhancing the fault features of multi-spectral remote sensing images based on multi-spectral images, panchromatic images and DEM is proposed, and the interpretation of faults based on the change of topographic and water features is established. There is a NW-trending distribution and a new Youjiang secondary active fault with a length of about 40km between the Shanzhai fault zone and the Youjiang fault zone, which is verified by the field seismic geological survey. In multivariate remote sensing information fusion, the fusion methods such as KL transform, HIS transform, product transform, ratio transform, and wavelet transform are compared comprehensively, and the principal component analysis is performed on the fused image to determine the image enhancement method and solution of product transform fusion The base map, highlighting the active fracture features.
