精灵4 RTK无人机在土地整治项目复核中的应用

当前土地整治项目规模大、数量多，采用传统的方式进行项目的复核耗费大量的劳动力，且效率低下。精灵4 RTK无人机的面世以及航测技术的快速发展，为土地整治项目复核提供了全新的技术手段。以我国南方某土地整治项目为例，采用精灵4 RTK无人机进行外业航摄，利用Metashape和Smart3D等软件进行内业处理生产正射影像图和三维模型，与竣工图进行叠加，并进行统计分析。对航测成果的精度进行统计后认为，无人机航测成果满足土地整治项目复核的精度要求。

Application of spirit 4 RTK UAV in land consolidation project review

At present，the scale of land consolidation project is large and the number is large.The traditional way to review the project costs a lot of labor and is inefficient.With the advent of spirit 4 RTK UAV and the rapid development of aerial survey technology，it provides a new technical means for land consolidation project review.Taking a land consolidation project in South China as an example，field aerial photography was carried out by using spirit 4 RTK UAV，and interior processing was carried out by using Metashape and Smart3D software to produce orthophoto map and 3D model，which were superimposed with the as built drawing，and were compared and statistically analyzed.Through the accuracy statistics of aerial survey results，it shows that the UAV aerial survey results meet the accuracy requirements of land consolidation project review.
