倾斜摄影模型轻量化及网络加载关键技术研究

Research on Key Technologies for Lightweighting and Network Loading of Oblique Photography Model

随着实景三维中国建设的推行和开展,倾斜摄影模型作为城市级实景三维主要数据类型,因其高度还原的真实场景,逐渐在越来越多的行业生产中充当着数据基底的作用。尽管如此,这种高精度的模型也面临着数据量大、显示效率低等挑战。针对这些问题,文章提出一套综合的模型轻量化和网络动态加载技术方案,以四川省某区域的倾斜摄影数据作为实例,验证了这些技术路线的有效性。研究结果显示,该方案显著提升了倾斜摄影模型的显示效率,为其在多个行业的生产应用开辟了新径。

With the implementation and development of constructing 3D real scene in China,the oblique photography model is used as the main data type of city-level 3D real scene,and has gradually played the role of database in more and more industry production because of its highly restored real scene.Nevertheless,this high-precision model also faces challenges of large data volume,low display efficiency,and so on.To address these issues,this paper proposes a set of comprehensive model lightweight and network dynamic loading technology solutions.Taking the oblique photography data of a certain area in Sichuan province as an example,the effectiveness of these technical routes is verified.The research results show that this scheme significantly improves the display efficiency of the oblique photography model,opening up new paths for their production application in multiple industries.
