摘要
这里论述了应用遥感图像和数字高程模型(DEM)的融合技术,对在西部高原区机场建设(昆明小哨机场)研究区进行三维可视化处理的技术方法。在3S(RS、GIS和GPS)技术支持下,对遥感图像进行数据融合、图像增强、影像正射精校正等处理后与高精度DEM融合,制作研究区景观的三维遥感虚拟动态模型。通过分析三维可视化图像,结合野外考察资料,对机场建设工程研究区域内的构造地质、工程地质、环境地质等特征信息进行了提取和综合评价。结果表明:三维影像技术在机场建设工程中具有一定优势,可以为西部高原区机场建设工程决策者和工作者提供科学依据。
The paper discusses the technique means of the three-dimensional visualization processing which apply the fusion technique of RS image and DEM in west altiplano aerodrome building project.Based on the '3S'(RS,GIS and GPS) techniques,the working procedure as the following: multiply waves band compound,image tone,data fusion,orthograph image processing,and high precision DEM build.Then the three-dimensional RS dummy dynamic model of the TengChong's aerodrome scene is built.Meanwhile,the paper synthetically evaluates tectonic geology,engineering geology and environment geology by simulating 3D visualizing RS dynamical models and the field survey data.The result reveals that the three-dimensional technique is preponderant in the aerodrome building project,and the method offers science foundation for the decision-makers and operators of the west altiplano aerodrome building.
