摘要
针对大面积的带状测绘区域精度要求,论文提出不同控制点布设方案下4D产品精度验证方法。首先,采用消费型飞马V100垂起无人机进行航摄,获取多视影像数据及响应的POS数据,并对POS数据进行后差分处理;然后,利用PCI软件的Geomatica Banff模块进行多视影像连接点提取结合Photoscan软件的At模块进行空三解算;最后,通过不同控制点布设方案试验,探讨像控点密度对航摄生成测绘产品精度的影响。实验总结了一种适合平原地区像控点布设方案,可供其他工程参考。
To meet the accuracy requirements of large-area strip mapping area,the accuracy verification method of 4D products under different control point layout schemes is proposed.First,the consumer Pegasus V100 is used to take aerial photos,obtain multi view image data and responding POS data,and perform post differential processing on POS data;Then,the Geomatica Banff module of PCI software is used to extract the connection points of multi view images,and the At module of Photoscan software is used to solve the empty three-dimensional problem;Finally,the influence of the density of image control points on the accuracy of aerial photographing mapping products is discussed through the test of different control point layout schemes.The experiment finally proposes a scheme for the layout of image control points suitable for plain areas,which can be used as reference forotherprojects.
