摘要
在正射影像的镶嵌处理中,需要进行镶嵌的正射影像有时会出现"非规则边缘",称之为非规则正射影像。本文针对非规则正射影像特点,采用自动化处理流程提取每一幅正射影像的有效像素区域多边形、计算相邻影像重叠区域及分割线以及生成经过自动拓扑编辑的镶嵌多边形网络,将手工镶嵌转化为自动镶嵌处理,有效提高了工作效率。
The DOMs with irregular borders are called irregular DOMs during mosaicking processing.In this paper,new automatic solutions were serially adopted to generate valid polygon area of each DOM,to get seam-lines of overlapped area between two adjacent DOMs,and to obtain polygons network corrected by topological rules.The mosaicking efficiency was improved when manual mosaicking methods were replaced by automatic ones.
