| 摘 要： | 在DSM滤波和权值确定的基础上,提出了一种基于DSM的遥感图像拼接线自动提取方法。该方法首先基于流水模型的基本原理设计了拼接线自动选择规则,然后利用数学形态学对自动提取的拼接线进行了膨胀处理。实验结果表明,该方法提取的拼接线能够有效地规避建筑物投影差等问题,确保了自动拼接线提取的有效性。

| Abstract: | On the basis of DSM filtering and weight determining,a method of remote sensing image mosaic line auto-extraction based on DSM was presented.This method first applied the basic principles of flow model to design the rule of stitching line select automatically,and then used mathematical morphology approach to process the stitching line.Experimental results showed that the stitching line can effectively circumvent the building displacement,ensure the effectiveness of automatic stitching line extraction. |
