| 摘 要： | 植被覆盖在我国南方具有普遍性。为了充分提取地质构造信息,有必要进行数字图象组合处理。事实证明,同态滤波处理是揭示植被覆盖区地质构造信息的有效手段,而主成分分析和斜变换处理在增强形态特征信息方面也有重要作用,上述处理手段在识别岩石类型及地貌单元方面也有很好的效果。

| Abstract: | The most distinct character of a vegetation-covered area is the transfer of the geotectonic information in an indirect way. This is because the vegetation tends to conceal the tectonic appearance to a large extent. The function of digital image processing is to try to recognize the covered tectonic information in order to reflect the geostructure in a more realistic way than the conventional landsat image does. Our researches show that through the analysis of characteristic information of vegetation in remote sensing image treated for specific composite function, the recognition of structural information can be realized.The application of common-made filtering, principle component analysis and slant transform, as well as their value-effectiveness in geolggy are discussed in this paper, and the related parameters of processing are given. The role of digital image processing of geostructural information over a vegetation-covered area in solving actual problems is also described with special reference to the results of processing taking Teng-Chong-Lianghe region, Yunnan province as an example. |
