摘要
数字正射影像(DOM)是对航空航天像片进行数字微分纠正和镶嵌,按一定图幅范围裁剪生成的数字正射影像集,是消除了变形误差及投影差并以数字方式存储的影像地图,是基础地理信息系统的重要数据。该文结合芜湖市1:1000DOM制作为背景,探讨了具体的制作流程以及质量控制方法,包括影像获取、空中三角测量、DEM生成和DOM成果质量检查4个阶段的质量控制措施,相信对从事相关工作的同行能有所裨益。
Digital Orthophoto(DOM)is a set of digital orthophoto images generated by digital differential correction and mosaic for aerospace photos,which is an image map that eliminates deformation error and projection error,and is an important data of basic geographic information system.Based on the background of 1:1000 DOM production in Wuhu City,this paper discusses the specif ic production process and quality control method.The qua l it y control measures include image acquisition,aer ia l tr iang ulation,DEM generation and DOM result quality inspection,which is believed to be benef icial to the peers engaged in related work.
