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 select the mosaic line of orthophoto to avoid the above ground features such as houses and trees, and to avoid the area with large color contrast on the orthophoto to be spliced, And automated production is of great significance. A method based on ant colony algorithm is introduced to automatically select inlaying lines of orthophotos. Experimental results show that this algorithm can quickly and effectively select the inlaid lines of orthophotos and realize the automatic seamless mosaic of DOM in surveying and mapping.
