摘　　要：在VirtuoZoAAT系统的空中三角测量测区接边中,相邻测区的重叠区域内存在许多同名不同位(即在两接边测区内具有相同点号但不在同一位置)的连接点,实际作业生产中,往往需要修改这些点在其中一个测区内的点名,若逐一打开每个点进行手动修改,工作量十分繁重。本文设计了测区接边辅助程序,实现了对同名不同位连接点的自动修改和接边点的自动挑选。应用结果表明,使用该程序,节省了接边作业时间,提高了作业效率。In block joint of VirtuoZoAAT aerial triangulation system,there are many connective points which have the same name but not been in the same place in the overlapping regions of adjacent blocks.In production,it is necessary to modify the names of these points in one block,if we change them one by one,the workload is very heavy.This paper design a program to achieve automatic modification of connective points which have the same name but not been in the same place and automatic selection of block joint points.The application results show that the use of program has saved time for block joint operations,and improved work efficiency.
