【摘要】：随着科学技术、计算机技术以及遥控设备的发展,无人机技术的发展也越来越快速。无人机的体积较小、重量较轻能够到达作业人员无法到达的区域进行作业,在应急系统中的应用也越来越多。在小范围的区域内获取影像数据的速度非常快,能够快速成图,为应急救援等提供可靠的依据。无人机技术应用越来越广泛,对其的硬件设备和软件设备的要求也越来越高,无人机从飞行控制系统、通信和数据处理等技术也越来越成熟。无人机在小区域内大比例尺成图的应用也更普遍。由于外界环境因素、硬件设备以及数据处理手段的限制,在大比例尺测图上面还需要进一步的研究与验证。本文对拓普康天狼星无人机系统进行了研究,主要从无人机系统的研究现状、组成、影像处理的技术、工作流程、成图精度等进行了介绍。结合天狼星无人机在青海省果洛藏族自治州的试验项目介绍天狼星无人机制作1:2000和1:500比例尺的DEM、DOM的工作流程。并对这两种比例尺的精度进行验证。其主要的研究内容包括:(1)介绍了拓普康天狼星无人机测图系统的构成和数据处理技术。主要介绍了飞行控制系统MAVinci Desktop控制软件的使用方法和数据后处理软件Agisoft PhotoScan的主要操作流程。(2)在拓普康天狼星无人机测图系统的基础上,通过采用实时动态RTK技术、高精度的测图技术、数据处理技术,实现了利用无人机测图系统制作1:2000和1:500比例尺的DOM、DEM;经过试验验证,检查DOM、DEM的精度,证明了该无人机系统获得的影像经过处理后获得的DOM的平面精度和DEM的高程精度都达到了相关测量规范的要求。(3)对使用拓普康天狼星无人机制作的两种大比例尺地图进行分析对比。表明该无人机测图系统打破了传统航空摄影测量的方式,不需要进行布设像控点的外业测量作业,使工作效率提高了,节约了成本。其影像数据处理的过程是由计算机自动进行处理的。
[Abstract]:With the development of science and technology, computer technology and remote control equipment, UAV technology is developing more and more rapidly. Unmanned aerial vehicles (UAVs) are smaller in size and lighter in weight and can be used to operate in areas beyond the reach of operators, and are increasingly used in emergency response systems. The speed of obtaining image data in a small area is very fast, which provides reliable basis for emergency rescue and so on. The application of UAV technology is more and more extensive, and the requirements of its hardware and software equipment are more and more high, and the UAV technology of flight control system, communication and data processing is becoming more and more mature. UAVs are also more commonly used in large scale mapping in small areas. Due to the limitation of external environment, hardware and data processing, further research and verification are needed on large scale mapping. In this paper, the research of Tuopcon Sirius UAV system is studied, including the research status, composition, image processing technology, workflow and mapping accuracy of UAV system. Based on the experimental project of Sirius UAV in Guoluo Tibetan Autonomous Prefecture of Qinghai Province, this paper introduces the work flow of Sirius UAV in making DEMMO-Dom with scale of 1: 2000 and 1: 500. The accuracy of these two scales is verified. The main research contents include: 1) introduce the structure and data processing technology of Topcon Sirius UAV mapping system. This paper mainly introduces the application method of flight control system MAVinci Desktop control software and the main operation flow of data post-processing software Agisoft PhotoScan. On the basis of Topcon Sirius UAV mapping system, it adopts real-time dynamic RTK technology. The high precision mapping technology and data processing technology have realized the use of UAV mapping system to make DOMDEM on scale of 1: 2000 and 1: 500. It is proved that the plane accuracy of DOM and the elevation accuracy of DEM obtained by the UAV system after processing meet the requirements of relevant measurement specification. The map is analyzed and compared. It is shown that the UAV mapping system breaks the traditional aerial photogrammetry method and does not need to carry out the field surveying with the image control points, which improves the working efficiency and saves the cost. The process of image data processing is automatically processed by computer.
