摘要
利用无人机实施地形测绘工作中,由于影像之间姿态角度变化较大,使得INPHO软件在空三加密时无法提取足够的连接点。针对这一问题,本文提出了使用ContextCapture提取影像的连接点,然后在INPHO中完成空三加密计算的优化方案,并针对两套软件之间的数据衔接编写了转换程序,从而可以有效利用软件的各自优势,解决连接点提取的问题,并用实际案例验证了该方法的有效性。
In the terrain mapping by unmanned aerial vehicle(UAV),due to the attitude angles of images varys widely,INPHO could’t extract enough tie points in aerotriangvlation.In order to solve this problem,this paper deduced a new optimization workflow which is using of ContextCapture to extract tie points first,and then completed the calcution of aerotriangulation in INPHO.And a conversion program was coded for the data transformation between the different software.It can effectively utilize the advantages of different software to solve the problem in extracting tie points.The effectiveness and reliability of the workflow are verified by experiments.
