快速准确地确定匹配参照点对是实现基于点模式指纹识别的一个关键问题，针对该问题本文提出了一种基于脊线校准的确定匹配参照点对的新方法。该方法首先利用细节点间的距离、类型以及细节点与脊线样点之间构成的网状结构来构建新的局部特征向量，然后在这些结构特征向量空间中搜索最为相似特征向量，确定出最优匹配参照点对。实验结果表明，本文提出的算法不仅速度快，而且准确性也有了较大提高。

Identifying the minutiae correspondences between two fingerprints is crucial for minutiae-based fingerprint matching. With respect to the matter, this paper proposes a new algorithm for fast reference minutiae pair selection to alignment the minutiae set. Introducing the ridge information into the selection process and finding a novel net structure, we specify the most similar pairs based on each of these net structure pairs. Experiments on two sets of fingerprint images show that the proposed algorithm is fast with high accuracy.
