As a technology of remote sensing information's comprehensive treatment and analysis, the research of multi-source remote sensing image fusion is becoming an important research direction in the remote sensing field. Based on analyzing and summarizing existing document and researching result, taking panchromatic images of high spatial resolution and multi-spectral images of low spatial resolution as data resource, this thesis draws forth the basic concept of multi-source remote sensing information fusion, analyzes and summarizes the level, model, structure and the technological character of multi-source remote sensing information fusion. With the quality evaluation criterion of fused images, this paper indicates that it is an effective way to evaluate the quality of fused image and the function of fused method to combine subjective qualitative evaluation with objective quantitative evaluation by carrying on fused test analysis to the remote sensing image of different spatial resolution. At the same time this paper analyzes synthetically and compares different fusion methods such as weighted fusion, product fusion, Brovey fusion, high-pass filtering fusion, Munechicka fusion in spatial domain and triangle HIS transform fusion, wavelet-transform fusion in transform domain. It offers scientific evidence for choosing the remote sensing information fusion method.Remote sensing technology provides new data resource and the way of exploring the earth for geoscience application. Based on the basic idea of geoscience analysis, this paper discusses the developing history of remote sensing information's geoscience handling and analysis and the development of intelligent remote sensing geoscience analysis; It draws forth the concept of intelligent remote sensing image interpretation and describes the image feature of rock, stratum structure, hydrology, vegetation, human, deep geological fracture and other information of geology in remote sensing information. According to the data of abnormal gravitational, magnetic field and the character of remote sensing image in the Ordos basin, it carry on comprehensive multi-source information analysis to the structure and the evolution of the basin, interprets the annular body(structure), studies the spatial relationships between the annular body(structure) and the coexistence of oil, gas pool, coal bed uranium deposits and other multi-energy resource, sets up the exploration thread that mineral annular structure reflects and the regularity of the rich location of minerals. It can offer valuable scientific evidence for forecasting, evaluating and the exploitation of multi-energy minerals in the Ordos basin.Using 3S technology, digital processing technology of remote sensing and virtual reality comprehensively, the virtual three-dimensional animated series map of researching area can be generated according to some scales and flying routes by the data fusion of remote sensing information, the generation of high-precision DEM, image integration and other procedures. Practice indicates that it is very feasible to apply the remote sensing image geological interpretation and image dynamic analysis methods to remote sensing geoscience research.
