摘要
根据武当地区的遥感影像,以地理信息系统为技术平台、区域构造为主要研究对象,采用遥感图像增强技术,解译了大中型断裂;采用基于径向基函数(RBF)神经网络的模式识别,结合二进制小波变换目视解译了褶皱;采用Haar小波变换方法解译了韧—脆性剪切构造;利用机助处理方法对印支期后多条断裂信息进行了解译,直观地表述了武当地区的构造面貌。通过对解译构造进行定量分析,阐明了武当地区的总体构造格局和发育状况,并结合野外地质调查对比,进一步验证了解译成果的准确性。这项工作为深入开展地质调查和构造控矿研究提供了基础资料,对成矿预测有一定的指导作用。
According to the remote sensing image of Wudang area,taking geographic information system as technology platform combined with the remote sensing image enhancement technology to study regional structure,then the large and medium-sized fracture was deciphered.Meanwhile,the fold was deciphered based on the Radial Basis Function（RBF）neural network pattern recognition combined with the binary wavelet transform visual,and we employed the Haar wavelet transform method to further interpret the ductile-brittle shear structure.Additionally,using the machine to help processing method for multiple fault information after indo-chinese epoch to decipher,it was found that the structural features of the Wudang area were intuitively described.Through investigations of the quantitative analysis of interpretation structure,the results displayed the general tectonic framework of the Wudang area and development status,moreover,it can further verify the understanding into the accuracy of the result combined with field geological investigation and comparison.Therefore,the work in this paper has a certain guiding role and it can provide basic data for further study on geological survey and tectonic ore-controlling.
