无人机倾斜摄影测量技术在农村房地一体确权项目中的应用研究

Research on the application of UAV oblique photogrammetry technology in rural house and land right determination project

倾斜摄影测量技术是一种通过多角度拍摄地面物体,然后利用摄影测量原理进行三维重建的技术,它可以在农村土地登记测绘过程中发挥重要作用。文章通过无人机航拍获取地形、地貌、建筑物等信息,形成高精度、高分辨率的影像数据,通过对航拍的影像进行处理,可以生成数字正射影像图和三维实景模型,进而得到测区线划图,最终实现为农村土地确权提供准确的基础数据的目的。实验结果表明,将该技术应用于农村土地确权项目中具有可行性,成果精度满足规范要求。

Oblique photogrammetry is a technique that photographs ground objects at an multiple angle and then uses photogrammetry principles to reconstruct them in three dimensions.It can play an important role in the process of rural land registration and mapping.In the article we obtain terrain,landform,buildings and other information through UAV aerial photography,and form high-precision and high-resolution image data.By processing the aerial images,digital orthophoto images and 3D real-life models can be generated,leading to the generation of DLG,the ultimate goal is to provide accurate basic data for rural land determination.The experimental results show that applying this technology to rural land determination projects is feasible,and its accuracy meets the regulatory requirements.
