低空无人机图像处理技术研究

Research on Image Processing Technology of Low Altitude UAVs

无人机系统作为地球观测的基础设施之一,以其机动性、高速性、灵活性、经济性等显著的技术优势,已广泛应用于国家经济建设的各个领域,如农业监测、资源开发、灾害应急处理等。本文以实际工程为例,阐述了在eBee无人机的基础上,利用专业的无人机数据处理软件UASMaster制作数字正射影像地图的方法和技巧。最后,通过两种方法详细分析了DOM的精度,将DOM与区域的现有DLG重叠,并将现有1∶1000比例DLG的点与立体模型的相应检查点进行对比。

As one of the earth observation infrastructure,UAV system has been widely used in various fields of national economic construction,such as agricultural monitoring,resource development,disaster emergency response and so on,due to its remarkable technical advantages of mobility,high speed,flexibility and economy.Taking an actual engineering as a case study in this paper,it expounds the method and skill of making digital orthophoto map by using professional UAV data processing software UASMaster on the basis of eBee UAV.Finally,the accuracy of DOM is analyzed in detail through two methods,the DOM is overlapped with the existing DLG of the region,and the points of the existing 1∶1000 DLG are compared with the corresponding checkpoints of the stereo model.
