摘　　要：针对双相机数字工业摄影测量中的人工标志点自动匹配问题,设计了一种基于相对关系不变性的图像匹配算法,根据平缓过渡曲面上相邻点间相对关系在两张像片上一致的原理,解决了两张像片的标志点自动匹配问题。3组实验表明,该算法匹配正确率高,匹配速度快,能够满足动态测量数据处理的需求。An image matching algorithm based on invariance relative relationship was designed against the automatic matching problem of artificial targets in dual camera digital industrial photogrammetry. The automatic matching problem of artificial targets was solved by the algorithm in the case of only two images, according to the principle that the relative relationship of adjacent points on smooth transition surface was consistent on two images. The algorithm has the advantages of high matching rate, low matching error rate and fast matching speed which was proved by three groups of experiments, and it is also able to meet the needs of dynamic measurement data processing.
