针对数字近景摄影测量中的人工标志点快速自动匹配问题，提出了一种基于双片空间前方交会的匹配算法。
A new matching method based on two-image space intersection was developed, aiming to the fast automatic matching of artificial target points in digital close range photogrammetry.
近景摄影中的场景较为复杂，通常不能采用常规航空摄影测量中的摄影方式，而是以单摄站旋转拍摄、多光束交会的方式进行。
Scenes in close-range photogrammetry are complex, common photograph methods are not suit here. We employ rotating station to take photos and make multi-ray intersecting.
