摘要
通过对立体像对测图范围实质的分析,利用加密成果,批量得到测区内的每个像对的测图范围文件,既能满足精度要求,又能提高作业效率。
Through analyzing the nature of mapping scope of stereopair, and by using encryption results, this paper obtains in batch the mapping scope files of each stereopair in the survey area, which not only meets the demand of precision, but also improves the efficiency of operation.
