融合多元遥感信息的新右江次级活动断裂解译

Interpretation of Newly Youjiang Secondary Active Fault Mergedwith Multiple Remote Sensing Information

    摘要
  • 摘要: 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。

     

    Abstract: An enhancement method of active faults merged with DEM,panchromatic,multispectral re-mote sensing images is proposed.Interpretation sighs of active faults are established based on spatialfeature variation of terrain and water.A newly Youjiang secondary active fault,40km long,NW-tren-ding extending,is discovered between Bama-Mashan fault and the Youjiang fault.Combined withseismic geological data,the interpretation results are compared and verified.In the process of imagemerging,the KL transformation,HIS transformation,Multiplicative transformation,Brovey trans-formation and Wavelet transformation are completely compared.With principle components analysisof merged image,Multiplicative transformation is selected to produce enhanced image and interpreta-tion map.The feature of active fault is outstanding ultimately.
