[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.
