摘　　要：为了解决三维地球在可视化展示时纹理添加技术存在分辨率低、贴图不真实等问题,本文结合遥感影像与自定义细节纹理两种贴图的优势,在场景渲染时进行自动融合切换,提高了三维地球贴图质量,为三维地球相关工程项目建设提供了一种新的纹理添加方法。该方法通过遥感影像自动获取地物矢量范围,依据相关参数在系统屏幕可视范围内使用遥感影像和自定义细节纹理对三维地球进行贴图,既保留了遥感影像的真实性,又在镜头拉近重点位置时展现高质量细节纹理,一定程度上解决了三维地球可视化中纹理贴图存在的问题,具有工程化应用价值。To solve the problems of low resolution and unreal texture in the visualization display of 3D Earth,this paper uses the advantages of remote sensing images and custom detail textures to automatically fuse and switch during scene rendering,it improves the quality of 3D Earth texture and provids a new texture addition method for 3D Earth related engineering projects.This method automatically obtains the vector range of ground objects through remote sensing images,and uses remote sensing images and custom detail textures to map the 3D earth within the visible range of the system screen based on relevant parameters.It not only preserves the authenticity of remote sensing images,but also displays high-quality detail textures when the camera zooms in on key positions,which to some extent solves the problem of texture materials in 3D Earth visualization and has engineering application values.
