倾斜摄影与近景摄影相结合的山地城市实景三维精细化重建与单体化研究

无人机倾斜摄影实景三维模型是一种能够对复杂山地环境较好感知和表达的有效手段之一。本文针对复杂山地城市开展倾斜摄影实景三维存在的问题，提出了适应于山地区域的多尺度的影像获取策略，并通过与近景摄影测量融合建模的方法，实现了对山地城市倾斜摄影实景三维模型精细化建模的目的；同时，对实景三维模型的单体化方法进行了介绍及对比分析，对后期山地城市开展倾斜摄影提供了一定的技术参考。

Research on 3D Fine Reconstruction and Model Singling of Mountainous City Combined with Oblique Photography and Close Range Photography

The actual 3D model based on the UAV oblique photography is an effective way to perceive and express the complex mountain environment. To solve the problems in the generation of actual 3D model based on oblique photography for mountainous cities, a multi-scale image acquisition strategy suitable for mountainous region and a method of fusion modeling with close range photogrammetry is proposed in this paper. Experiments show that this method realizes the goal of precise modeling of the actual 3D model of oblique photography in mountainous cities. And then, the methods of actual 3D model's singling are introduced and compared. This paper provides some technical references for developing oblique photography in mountainous cities in the future.
