【摘要】：无人机遥感在数字城市建设、重大灾害救灾中拥有着较大优势,并且已经发挥了不可替代的作用。然而其发展中却存在一些问题,本文综合无人机遥感整个作业过程中遇到的这些问题,利用了目前一些现有的方法,同时提出了一些新的方法,设计了无人机飞行管控系统和无人机遥感数据处理软件系统,来分别解决无人机飞行控制和数据处理过程中遇到问题。论文设计了一个无人机飞行管控系统,通过使用Internet通讯技术和服务器技术,使得用户可以不受其他条件限制,通过可连接互联网的设备即可方便直观的查看、控制、规划、管理无人机飞行作业任务。同时也设计了一套无人机遥感数据处理软件系统,通过使用字符界面的服务器作为运算核心,图形界面程序作为客户端,使用户可以不受地理位置、使用设备的影响,都可以享受遥感数据处理的云端服务,同时服务器还可以向公众提供付费的数据处理服务。论文主要在以方面进行了研究和创新： 1)利用多种硬件、软件技术和方法,设计了一个无人机外业作业管控系统和一套简单高效的无人机遥感数据处理软件,简化了无人机遥感操作和影像处理难度。 2)在无人机上使用嵌入式程序,利用GPS-OEM芯片等廉价设备通过移动网络控制无人机飞行,并通过分析飞行姿态寻找传感器间的位置不变关系,推导出一套解决同步问题提高遥感影像外方位元素精度的方法。 3)通过对多种影像处理算法的分析,发现了RANSAC算法剔除误匹配点存在隐患及其规律；同时综合利用各算法优点提出了智能匹配的算法,实现了遥感影像匹配的智能化；最后通过实验总结讨论了影像拼接的必要性,提出替代方案。
[Abstract]:UAV remote sensing has great advantages in the construction of digital city, major disaster relief, and has played an irreplaceable role. However, there are some problems in its development. This paper synthesizes these problems in the whole process of UAV remote sensing, makes use of some existing methods, and puts forward some new methods to design UAV flight control system and UAV remote sensing data processing software system. To solve the UAV flight control and data processing process encountered problems. A UAV flight control and control system is designed in this paper. By using Internet communication technology and server technology, users can not be restricted by other conditions, and they can be viewed, controlled and planned conveniently and intuitively by means of internet-connected devices. At the same time, a UAV remote sensing data processing software system is designed. By using the server with character interface as the operation core and the graphical interface program as the client, the user can not be subjected to geographical position. The impact of the use of the device, can enjoy remote sensing data processing cloud services, while the server can also provide the public with the payment of data processing services. The thesis mainly carries on the research and the innovation in the aspect:. 1) using various hardware, software techniques and methods, a UAV field operation control system and a set of simple and efficient UAV remote sensing data processing software are designed, which simplifies the difficulty of UAV remote sensing operation and image processing. 2) using embedded program on UAV, using cheap equipment such as GPS-OEM chip to control UAV flight through mobile network, and finding the position invariant relationship between sensors by analyzing flight attitude. A set of methods to improve the precision of external azimuth element of remote sensing image is derived. 3) through the analysis of various image processing algorithms, it is found that the RANSAC algorithm eliminates the hidden trouble and its rule of mismatch points, and at the same time, the intelligent matching algorithm is put forward based on the advantages of each algorithm, and the intelligence of remote sensing image matching is realized. Finally, the necessity of image stitching is summarized and discussed through experiments, and an alternative scheme is put forward.
