摘要：The idea and concept of Measurable Virtual Reality (MVR) based on seamless stereo-orthoimage database is firstly put forward. The meanings and basic principle of MVR is discussed in this paper. Based on stereovision of human's eyes, the main idea of MVR 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, then a large area 3D virtual landscape environment can be formed without y-parallax. 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 project design in such 3D virtual landscape environment will be more intuitionistic and more realistic. The application fields and the prospects of MVR are also presented in this paper. At last, some experiment results of MVR are discussed
