基于UE的倾斜摄影测量模型可视化方法研究

Research on Visualization Method of Oblique Photogrammetry Model Based on UE

倾斜摄影测量模型是数字孪生城市及实景三维中国建设的重要组成数据,前人针对可视化城市规模的场景提出了许多方法,但其可视化效果仍然无法满足用户对场景真实沉浸式体验感的需求。本文研究设计了一种基于虚幻引擎(UE)的倾斜摄影测量模型可视化方法,该方法以场景真实沉浸式体验为目标,研究了UE支持的3Dtiles倾斜模型数据格式加载方法,并总结了倾斜摄影测量模型在UE的处理加载流程,设计了实验来验证方案的可行性,基于UE实现城市级倾斜摄影测量模型的加载,结果表明,本文的方法可以显着提高倾斜摄影测量模型可视化体验感且三维场景更具有真实性。

The oblique photogrammetry model is an important component of the digital twin city and the real 3D China construction.Many methods have been proposed for visualizing the scene of the city scale,but its visualization effect still cannot meet the needs of users for a real and immersive experience of the scene..This paper researches and designs a visualization method of oblique photogrammetry model based on Unreal Engine(UE),which aims at the real immersive experience of the scene,the 3D tiles skewed model data format loading method supported by UE was investigated,and summarizes the results.The processing and loading process of the oblique photogrammetry model in UE is discussed,and experiments are designed to verify the feasibility of the scheme.Based on UE,the loading of the city-level oblique photogrammetry model is realized.The results show that the method in this paper can significantly improve the visualization experience of the oblique photogrammetry model.Sensation and 3D scenes are more realistic.
