摘要
近年来,倾斜摄影技术发展迅速,作为一种新型测绘手段,在各工程建设领域都得到了广泛应用。本文介绍了无人机倾斜摄影外业数据采集流程、技术指标及内业数据处理方法,同时基于水利行业发展现状及需求,介绍了倾斜摄影技术在水利勘测设计工作中的实际应用,如辅助工程查勘及场地分析,辅助线路规划及工程布置,高效且有针对性地生产测绘产品,进而缩短设计周期,在提高设计效率的同时保证了设计质量;此外,该技术能融合BIM、虚拟现实等新技术,辅助水利工程三维设计和表达,提高了设计水平和可视化效果,因此,实践证明倾斜摄影技术能有效应用于水利勘测设计中。
In recent years,oblique photography has developed rapidly.As a new surveying and mapping method,it has been widely used in various engineering construction fields.The present study introduced the field data acquisition process,technical indexes,and internal data processing method of the Unmanned Aerial Vehicle oblique photography.Based on the development status and demand of the water conservancy industry,the study also introduced the practical application of oblique photography in water conservancy survey and design,such as auxiliary engineering survey and site analysis,auxiliary line planning and engineering layout;It can also efficiently produce surveying and mapping products,thus shorten the design cycle,and improve the design efficiency and ensure the design quality;In addition,this technology can integrate BIM,virtual reality and other new technologies to assist the three-dimensional design and expression of hydraulic engineering,and improve the design quality and visualization effects.Oblique photography technology can be effectively applied in water conservancy surveys and design.
