| 摘 要： | 在利用搜索重合点水深比对法检查相邻两水深测量成果拼接质量过程中,通过展现重合点在拼接区域的分布情况,发现搜索的重合点存在相对总点数较少且分布不均匀的缺点,影响评估质量.针对上述问题,建立了网格选取剖面比对法,系统阐述了该方法的操作原理及其应用并通过实例验证取得了较好的结果,为水深测量成果相邻图幅拼接质量评估提供新的思路.

| Abstract: | Using the searching and comparing coincidence depth point method to evaluate the quality of maps splicing.Through showing the distribution of the coincidence points in overlap region,the disadvantage of this method is found that the coincidence points are less and not well-distributed,which would reduce the quality of evaluation.A new method selecting profile from grid data was built and achieved a good result in experiment.It is more helpful to evaluate the quality of maps splicing. |
