摘要
倾斜摄影技术已经在智慧城市、文物保护、应急救灾等方面得到较为广泛的应用,但在工程测量领域的应用还处于试验和推广阶段。本文基于倾斜摄影实景模型内业测制1∶500地形图生产应用案例,提出了地形要素提取的方法,并对成果进行了精度验证,可以为倾斜摄影技术应用于大比例尺地形图测绘提供一定的借鉴。
Oblique photography used in engineering is still experimental,although it is widely used in the smart city,cultural relics protection,emergency rescue,and so on. This article proposes a topographic feature extraction method and takes precision evaluation during the 1 ∶ 500 topographical map production using oblique photography panorama model. The research results also offer technology reference for large scale topographical map production based on oblique photography model.
