Abstract: The paper proposes a fingerprint matching method using ridge and the structure of ridge.First，the method sought for the reference minutiae according to ridge comparability and then sieves these reference minutiae according to the structure of ridge and vector triangle method.Last it uses a variable sized bounding box to match the two minutiae sets.Experiment results indicate that the method can locate the reference minutiae accurately，then perform the fingerprint matching quickly and correctly.

Key words: fingerprint matching, reference minutiae, ridge comparability, the structure of ridge

摘要： 提出了一种利用脊线和脊线结构信息进行指纹匹配的方法，即首先利用脊线的相似度初步确定若干参考点对，然后根据脊线间的结构信息利用矢量三角法对初步确定的参考点对进行筛选，最后用可变限界盒法进行匹配。实验结果表明，该方法能够准确地定位参考点对，快速正确地实现指纹匹配。
