摘要
传统三维模型的构建一般建设周期较长、费用昂贵。无人机倾斜摄影获取立体三维模型具备建设周期短、要素全、分辨率高、可量测、费用低等优点。倾斜摄影技术颠覆了以往正射影像只能从垂直角度拍摄的局限,通过在同一飞行平台上搭载多台传感器,同时从一个垂直、四个倾斜共五个不同的角度采集影像,将用户引入了符合人眼视觉的真实世界场景。作为国际测绘遥感领域近年发展起来的一项高新技术,无人机倾斜摄影可为测绘、规划、国土、智慧城市、应急、公安、旅游文化等领域提供高效的数据支持与服务。本文以MD4-1000四旋翼无人机为例,详细介绍了倾斜摄影内外业技术路线、流程工序关键点、质量控制措施等内容将为同类项目的开展提供有益借鉴。
The traditional construction of three-dimensional(3D) model has a time waste and high cost.The UAV tilt photography gets the 3D model more fast and comprehensive,and with high resolution,scalability and low cost.Instead of the traditional orthophoto only taken from the vertical angle,tilt photography technology carries multiple sensors on the same flight platform,which can acquire photos from five different angles,including one vertical and four inclined.This technology provides a real world scene for users.As a new technology developed in international mapping and remote sensing in recent years,the UAV tilt photography provides high efficient data support and service for surveying,planning,land,smart city,emergency,public security,tourism,culture and other fields.Taking MD4-1000 four rotor UAV as an example,this paper introduces the technical route,key points for the procedure and quality control measures of tilt photography,which provides a useful reference for similar projects.
