Multi-source Remote Sensing Information Fusion And Its Application To Active Faults Along Qinghai-Tibet Railway

The aim of the research of multi-source remote sensing image fusion is how toproduce new image from multiple source image data from different sensors and toobtain more comprehensive, external and intrinsical cognition of the same object. Asan important embranchment of data fusion, the research of multiple-source imagefusion has become a hot issue in the remote sensing field. Based on analyzing andsummarizing existing documents and research results, taking panchromatic images ofhigh spatial resolution and multi-spectral images of low spatial resolution as dataresource, this thesis draws forth the basic concept of multi-source remote sensinginformation fusion, analyzes the level, model, structure and the technologicalcharacter of multi-source remote sensing information fusion. Taking Dong Da TanQuick Bird images of different spatial resolution as the data resource, the fusionexperiment through six different fusion methods and the results analyses have beencarried on. It offers scientific evidence for choosing the remote sensing informationfusion method.The application of remote sensing provides a new approach for geoscience andhas greatly conquered the limitation of sight in the past. As a worldwide significantproject, the construction and operation of Qinghai-Tibet railway are confronted withthe technical problem of active faults. The bad conditions of Qinghai-Tibet Plateauincrease the difficulty of field survey, however, the technique of remote sensing canobtain the information of active rupture. The new image of 0.61m resolution fused byQuick Bird panchromatic image and multi-spectral true-color image(R3G2B1) canobtain the geometrical and structural characteristics of the active fault in Dong DaTan.Using 3S technology, digital processing technology of remote sensing and virtualreality comprehensively, the virtual three-dimensional animated series map of researching area can be generated according to some scales and flying routes by thedata fusion of remote sensing information, the generation of high-precision DEM,image integration and other procedures. High-precision virtual three-dimensionalanimated series map provide real, external and continuous terrain landscape images,which is helpful for the enhancement of information- extraction in the research area.
