摘要
介绍了2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∶1 000无人机航空摄影中某一块数据进行试验,对比分析两款系统实际处理流程和精度.主要结论如下:①Inpho和MapMatrix系统在处理1∶1 000无人机遥感数据时,空中三角测量精度和DOM成图精度、影像质量均能达到国标要求,两者平面精度相差不大,高程精度Inpho相对较好;②Inpho系统软件集成性高、操作性好,空中三角测量性能强、自动化程度高,MapMatrix系统需要调用PATB,处理数据量和效率没有Inpho高,需要人工编辑大量争议点;③MapMatrix在镶嵌成图和编辑方面更加便捷、高效.
Abstract
We described the processing flow,software features and advantages of two famous photogrammetric systems overseas Inpho and domestic MapMatrix system (including MapMatrix,DATMatrix and EPT) in UAV remote sensing image.With a piece of data of 1∶1 000 UAV aerial photography in Yanjiang District of Ziyang City as the experimental data,we compared the actual processing flow and accuracy of this two systems.The main conclusions were as follows:① In processing 1∶1 000 UAV remote sensing data,Inpho and MapMatrix system' s aerophotogrammetry accuracy and image quality all could meet the national standard,and there were little differences between the two planar accuracy,and Inpho' s height accuracy was relatively better than MapMatrix' s.② InPho system had high integration,good operability,strong aerophotogrammetry,high degree of automation;and MapMatrix system had to call PATB in aerophotogrannetry.The handling high data volumes and efficiency of MapMatrix system were less than Inpho,and it needed to manually edit a lot of the issue points.③ MapMatrix was more convenient and efficient in mosaic and editing images.
