Abstract
Abstract. With the development of real 3D model production technology and the expansion of application field, people pay more and more attention to the quality of real 3D model. However, how to measure the quality of today's real 3D model have been bothering its producers and users. In this paper, we analysed the quality model of real scene 3D model based on oblique photography from the perspective of the third party. Our analysis is guided by the application requirements of real scene 3D model, combined with the existing production technology level. Our analysis is guided by the application requirements of real scene 3D model, combined with the existing production technology level, we established the quality framework of real scene 3D model. This quality framework of real 3D model includes nine quality elements. Using this quality framework, we made a quality evaluation test in Yingjing County, Sichuan Provence. The test results show that the quality framework can fully reflect the quality of the real scene 3D model. The quality framework of real scene 3D model established in this paper solves the problem that it is difficult to evaluate the quality of real scene 3D model. The quality framework provides a basis for comprehensive and objective evaluation of real scene 3D model quality.

Summary
With the development of oblique photogrammetry technology, real scene 3D model emerges as the times require. We established the quality framework of real scene 3D model. They carry out sunshine and inundation analysis based on the model. They add planned building, vegetation or other geographical elements to the 3D model with the help of special software or directly. They need to see the designed surface landscape on real scene 3D model. It can provide basic data for DSM, DOM, DLG and so on These data is need in the construction of smart city. Model-based sunshine analysis, inundation analysis, collapse analysis and collision analysis are usually need
