【摘要】：本文在论述了无人机航测数据处理研究进展和WebGIS发展历程、研究现状基础上,介绍了两款著名的摄影测量系统,国外的Inpho和国内的MapMatrix系统(含MapMatrix、DATMatrix和EPT)在无人机遥感影像处理中的流程、软件特点和优势,并以资阳市雁江区1：1000无人机遥感数据为数据源进行实验,对比分析两款系统实际处理流程和精度。最后设计开发了无人机遥感数据发布展示系统,将无人机遥感处理后数据通过WebGIS发布展示,供用户快速访问、浏览。主要结论如下：(1)、Inpho和MapMatrix系统在处理1：1000无人机遥感数据时,空三精度和DOM成图精度、影像质量均能达到国标要求,空三中两者平面精度相差不大,空三高程精度和DOM成图精度Inpho相对较好。(2)、InPho系统软件集成性高、操作性好,空三性能强、自动化程度高；MapMatrix系统中空三使用DATMatrix,DEM使用MapMatrix, DOM使用EPT,三个软件都需单独安装;MapMatrix系统中空三需要调用PATB,处理数据量和效率上没有Inpho高,同时需要人工编辑大量争议点。(3)、InPho和MapMatrix系统在DEM生成、编辑功能上相差不大,但是InPho严格考虑断裂线和人工建筑,所生成的DTM和DOM精度比MapMatrix的高；MapMatrix在镶嵌成图和编辑方面更加便捷、高效。(4)、以无人机遥感为数据源,以3S技术为技术支撑,采用浏览器／客户端模式(B/S)开发,使用Flex富互联网程序技术、ArcGIS for Server和空间数据库等相关技术,本文设计、开发出的无人机遥感发布展示系统,便于Web端地图浏览、量测、搜索定位和土地利用分析,为无人机遥感快速增值服务起到示范作用。本次研究经历“无人机遥感外业航飞、像控点测量——无人机遥感数据内业处理——地理信息数据处理——WebGIS系统设计开发”,充分利用GNSS、RS和GIS技术,建成比较完整的测绘航空摄影和航空遥感数据获取、处理和服务框架链,为测绘航空摄影、航空遥感数据的商业化获取和增值服务起到抛砖引玉的作用。
[Abstract]:In this paper, two famous photogrammetry systems are introduced on the basis of discussing the research progress of UAV aerial survey data processing and the development course of WebGIS. The flow, software features and advantages of Inpho and MapMatrix systems (including MapMatrixDATMatrix and MapMatrix) in UAV remote sensing image processing are studied. The remote sensing data of 1: 1000 UAV in Yanjiang District of Ziyang City are used as data source. Compare and analyze the actual processing flow and precision of the two systems. Finally, the remote sensing data publishing and displaying system of UAV is designed and developed. The data after UAV remote sensing processing is released and displayed through WebGIS, which can be quickly accessed and browsed by users. The main conclusions are as follows: in the processing of remote sensing data of 1: 1000 UAV, the accuracy of space 3 and DOM mapping, the image quality can meet the requirements of national standard, and the plane accuracy of the two systems is not much different, the main conclusions are as follows: 1: 1 / 1 Inpho and MapMatrix system deal with the remote sensing data of 1: 1000 UAV. The accuracy of space three elevation and DOM mapping accuracy Inpho is relatively good. The software integration of InPho system is high, the operation is good, and the space three performance is strong. High degree of automation MapMatrix system hollow three use map Matrix Dem use MapMatrix, DOM use EPT.The three software need separate installation of MapMatrix system hollow three need to call Pat, processing data volume and efficiency is not as high as Inpho. At the same time, there are a lot of disputes about the need for manual editing. The InPho and MapMatrix systems are generated by DEM, but the editing function is not different, but InPho strictly considers the fracture lines and artificial buildings. The generated DTM and DOM are more convenient in mosaic mapping and editing than MapMatrix's high precision map matrix. It is highly efficient. The UAV remote sensing is used as the data source, the 3s technology is used as the technical support, and the browser / client mode is used to develop it. This paper designs and develops a remote sensing display system for UAV, which is convenient for map browsing, measuring, searching and positioning and land use analysis in Web terminal, using Flex rich Internet program technology, ArcGIS for Server and spatial database, and so on, in this paper, the remote sensing display system of UAV is designed and developed. For UAV remote sensing rapid value-added services play a role in demonstration. This research experience "UAV remote sensing field flight, image control point measurement-UAV remote sensing data processing-geographic information data processing-WebGIS system design and development", the full use of GNSS RS and GIS technology, A relatively complete frame chain of aerial photography and aerial remote sensing data acquisition, processing and service has been built, which will serve as a reference for commercial acquisition and value-added services of aerial photography and aerial remote sensing data.
