Research On Mission Planning And Data Processing Of Unpiloted Mapping System

Before the unpiloted mapping systems are equipped for army, our mapping units only has the ability of measuring but not capable of taking photos. At the initial developing stage, this situation is inevitable and rational. However, if the measuring and photographing work are separated too long, it will lead to a lot of problems such as delay on the period of mapping, high cost and so on. These problems are solved by using the unpiloted mapping system. As an important means of acquiring spatial data, unpiloted remote sensing technology has many advantages, such as long endurance, real-time image transmission, detection of high-risk areas, low cost and flexibility. Unpiloted remote sensing technology is a strong complement to satellite and aerial remote sensing. The combination of unpiloted remote sensing, satellite remote sensing and aerial remote sensing can form a comprehensive monitoring system of various height platforms. This thesis studied the technology of mission planning and remote sensing image processing, including the mapping site selection, route planning and image post-processing technology. This paper main work and innovations are as follows.1. The basic elements and the transformation models of reference coordinate system of the unpiloted mapping system are analyzed in this thesis. The theories, classification, restriction conditions, method and process of mission planning are expatiated. It is also provided in the thesis including the principle and method of airspace application, information collection and field selection in mission planning.2. Based on the restriction of the unpiloted mapping system capability and mission planning, the effect of these restriction on route planning is analyzed and the models are deduced.3. The general model of route plan for the unpiloted mapping system is deduced. Then, three classic planning methods are provided, which are the ordinal strips design, alternate strips design, and transmeridional strips design. These plans are meaningful for obtaining effective data and decreasing repeat and supplement aviation. By the analysis on experiment, these route planning methods are evaluated.4. The method for unpiloted remote sensing image processing is analyzed. And fast processing of the unpiloted mapping remote sensing images is realized by Pixel Grid. Finally, the correctness and reliability of the unpiloted remote sensing images processing are validated through experiments...
