【摘要】 数字正射影像(DOM)以其丰富的景观信息,高质量的几何精度而得到了广泛应用。以敦煌220窟内 壁西墙的DOM的生成为例,总结利用数字摄影测量技术制作数字高程模型(DEM)及在此基础上叙述了制作数 字正射影像图(DOM)的原理与过程。更多还原

【Abstract】 Digital Qrthoimage is widely produced and used because of its rich landscape information and high Geometric accuracy. In this paper the orthoimage making of inner west wall of No. 220 grotto in Dunhuang is selected as a case study to investigate how to create digitalelevation model (DEM) using digital photogrammetry and further more the principle and process of digital orthoimage maring.更多还原
