摘　　要：针对传统数字地籍测量存在生产周期长,测区内精度不均等问题,使用航测手段开展界址点地籍测量是地籍测量领域追求的目标。当前数字航摄仪具有几何精度高的特点,使影像地籍的实现成为可能。该文以国产SWDC数字航摄仪为基础,在获取高分辨率低空影像的前提下,开展5cm地籍界址点航测应用研究;阐述了具体测区的1∶500地籍界址点生产性航测试验。结果表明,GSD为4cm时,SWDC航测的平面精度优于5cm,满足高精度地籍界址点测量的精度需要,证明了国产SWDC实施精细航测的应用可行性。The goal of the cadastral survey is to apply photogrammetry technology in the boundary point cadastral survey.Currently,digital aerial survey camera has the advantage of high geometric precision,which makes the realization of image cadastral survey possible.This paper studied the application of photogrammetry for 5cm boundary point cadastral survey based on high resolution image procurement avail of domestic digital aerial survey camera SWDC.It dwelled on the productive photogrammetric test of 1∶500boundary point cadastrial survey.The result showed that the plane precision would be better than 5cm with the ground sampling distance of 4cm.The precision could meet the demand of boundary point cadastrial survey,furthermore,the feasibility of applying domestic SWDC in fine photogrammetry could be proved.
