摘要
近年来,随着计算机、遥感、摄影测量及其相关技术的飞速发展,使得通过快速获取地表信息并重建三维地表成为现实。遥感图像的三维可视化对于宏观观察者(如领导干部、项目决策者等)而言,其实际效果相当于乘坐在一定高度的飞行器上进行航空路线观察,方便其决策方案设计;对于遥感图像解译者(具体的工作人员)而言,高精度的三维影像动画系列图提供了可供反复使用的真实、客观、信息连续的宏观分析地面景观影像;对于项目施工方,可利用高精度的遥感三维影像快速准确地分析地形和计算土石方填挖量;在机场规划与设计过程中,设计净空模型,对机场净空进行评定。
With the rapid development of computer, remote sensing, photogrammetry and some correlative technology in recently years, it is a reality that getting the information on the earth＇ s surface fast and rebuilding the earth＇ s surface. High precision＇ s 3 D visualization of remote sensing images apply selection of aerial routes by aerial survey for maeroseopieal observers （such as the leaders and the project managers, and so on） , and provide gen- erally analytic ground-sight images that may be repeatedly used and characteristic of reality, objectivity and information series for the image interpreters. Even more, project working can analyse terrain exactly and calculate cubic meter of earth volume rapidly based on high precision＇ s 3D images. Through building solid model of airport clearance ,we can evaluate airport clearance condition on airport programming project.
