摘　　要：针对近景摄影测量中人工标志点的自动识别问题,提出了一种人工标志点的中心坐标提取方法。在布设了多个标志点的隧道断面图像中,通过背景消除、形态学处理、标志点区域划分和非标志点消除等过程,能够识别出人工标志点并提取其中心坐标,并运用近景摄影测量的相关技术计算出其实际坐标。上述方法通过VC++编程得到了实现,其结果说明了该方法的可行性。For the automatic recognition of artificial landmarks in close range photogrammetry, a method of picking up the center co ordinates of the artificial targets is proposed. Laying a number of landmarks on the tunnel section image,through the processes of cancellation of background,morphological processing,dipartition of landmarks areas,elimination of nonmarked points ere, artificial tar gets can be recognized and the coordinates can be extracted. And then calculate the actul coordinates by the related technology of close range photogrammetry .Moreover, using VC＋＋ language compiled a computer program to realize it. The result proved the practi cability of this method.
