摘　　要：自动选择正射影像的镶嵌线,使它避开房屋、树木等高出地面的地物,以及避开在待拼接正射影像上存在较大颜色反差的区域,在正射影像的无缝镶嵌与自动化生产中具有重要意义。介绍了一种基于蚁群算法进行正射影像镶嵌线自动选择的方法。实验结果证明,该算法能快速、有效地选择正射影像的镶嵌线,实现了测绘生产中DOM的自动化无缝镶嵌。Automatically selecting seam line, which should not cross buildings, trees, higher than ground, and the area with big gray difference between overlapping orthophotos, is important for seamless mosaicking and automated production of digital orthophoto maps （DOM）. An automated seamline detection method for orthophoto mosaicking based on ant colony system is introduced. The experimental result shows that this method can select seamline of orthophoto image with great speed and high accuracy, and realizes DOM automatic seamless mosaicking in surveying and mapping production.
