摘要
倾斜摄影技术突破传统垂直航空摄影的限制,从多角度获取影像,生成可量测的实景三维模型,并直接用于地形图测绘。本文基于实景三维模型进行1∶500地形图测绘应用研究,探讨了倾斜摄影的关键技术,总结基于实景三维模型的1∶500地形图测绘流程,结合实例的相关精度分析,验证了基于实景三维模型的1∶500地形图测绘的可行性,提供了一种新的大比例尺地形图生产模式。
Oblique photography technology breaks the limitation of traditional vertical aerial photography,generates a measurable 3 D model of the actual scene by images acquired from multi-views,witch can be directly used in surveying and mapping. This paper researches how to produce 1 ∶ 500 topographic map by real 3 D model,discusses the key techniques of oblique photography,summarizes the process of produce 1 ∶ 500 topographic map by real 3 D model,verifies the practicability of producing 1 ∶ 500 topographic map by real 3 D model according to accuracy analysis.Finally,a new production model of large scale topographic map is provided.
