无人机摄影测量技术在地籍测绘中的应用

Application of UAV Photogrammetry Technology in Cadastral Surveying and Mapping

无人机摄影测量是指采用多旋翼、固定翼的无人飞行器平台,搭载单镜头、多镜头的相机传感器,以及小型机载雷达等,进行无人机测量的一种先进测绘技术手段。无人机摄影测量是对传统航空摄影测量、摄影测量与遥感等测绘手段的有力补充,在小区域和飞行困难地区高分辨率影像快速获取方面具有明显优势。无人机摄影测量产品主要包括:航测4D产品、倾斜摄影测量等。近年来,相比传统测量,无人机摄影测量作业成本更低、效率更高、时效性更强,深受测绘行业的欢迎,在国土资源测绘中应用也越来越广泛。

UAV photogrammetry refers to an advanced surveying and mapping technology which uses multi-rotor and fixed-wing unmanned aerial vehicle platform,is equipped with single-lens,multi-lens camera sensors and small airborne radar for UAV surveying.UAV photogrammetry is a powerful supplement to traditional aerial photogrammetry,photogrammetry and remote sensing and other surveying and mapping methods.It has obvious advantages in the rapid acquisition of high-resolution images in small areas and areas with difficult flight.UAV photogrammetry products mainly include aerial survey 4D products,tilt photogrammetry,etc..In recent years,compared with traditional surveying,UAV photogrammetry has lower operating costs,higher efficiency and stronger timeliness,so it has been welcomed by the surveying and mapping industry and has become more and more widely used in land and resources surveying and mapping.
