中文摘要：

为了充分地开发和利用航空摄影测量所形成的立体模型，在二维无缝正射影像数据库的基础上，提出了无缝立体正射影像数据库的概念，即在摄影测量所形成的区域范围内，利用原始影像、定向参数及DEM，通过数字投影处理的方法，用无缝镶嵌的数字正射影像和立体辅助影像形成对摄影区域范围内无缝立体覆盖，即可以恢复摄影时记录的地形表面和地物碎部的三维信息，又可以通过立体观察设备进行无缝立体观察、浏览量测。为了方便立体观察、高精度立体量测和应用，对数字正射影像、立体辅助影像、像片定向参数及其DEM通过数据库的方式进行管理，形成区域范围内的无缝立体正射影像数据库。试验表明，无缝立体正射影像数据库具有良好的应用价值和应用前景。

英文摘要：

The idea and concept of the seamless stereo orthoimage database in a continuous block area is put forward. The principle and implementation of stereo orthoimage database are presented. Based on stereovision of human＇s eyes, the main idea of seamless stereo orthoimage database is to generate a seamless digital orthophoto quadrangles （DOQ） database from DEM and odd photos and generate additionally a digital stereo orthophoto partner （DSP） from DEM and even photos, and a large area 3D virtual landscape environment can be formed without y-parallax. The database is called seamless stereo orthoimage database formed by DOQ and DSP together. In such environment, the 3D measurement and analysis can be done under the interface of normal GIS or CAD systems without complex DPW. The 3D objects, such as houses, trees, cloverleaf junctions, geologic ruptures, and so on, which are not acquired during data acquisition at DPW, can be measured by end user himself. The case study and some potential applications are given at last.
