基于无人机倾斜摄影测量的农村房屋调查研究

Research on Rural Housing Survey Based on UAV Tilt Photogrammetry

无人机倾斜摄影已基本取代传统人工全野外测绘,成为小区域大比例尺测图的主流方式。本文以贵阳市龙田村为工程背景,探讨了无人机倾斜摄影测量技术在农村房屋调查测绘中的应用,通过对数据以及进行精度分析可知,界址点中误差为4.12cm,小于中误差5cm,满足国家规范精度要求。结果表明,单镜头无人机可以满足农房测量的精度要求,符合国家规范标准,也极大提高了工作效率、节省了大量人力、物力等资源。

In recent years,with the development of tilt photogrammetry technology,UAV tilt photography has basically replaced the traditional manual f ield surveying and mapping,and has become the mainstream method of small area large-scale mapping.Taking Longtian village of Guiyang City as the engineering background,this paper discusses the application of UAV incline photogrammetry technology in rural housing survey and mapping.Through the analysis of data and accuracy,it can be seen that the mean square error of boundary point is 4.12cm,less than 5cm,which meets the accuracy requirements of national standards.The results show that the single lens UAV can meet the accuracy requirements of Rural Housing measurement,meet the national standards,and greatly improve the work ef f iciency,save a lot of human and material resources.
