摘　　要：提出了一种基于Core点和特征点的指纹匹配算法,建立了用Core点确定参考点的数学模型,根据该模型确定了指纹的匹配范围,通过引入特征点到参考点的脊线条数因子n以提高匹配的精度.并以Visual C++6.0建立了该指纹识别算法的实验平台,对提出的指纹匹配算法进行了实验研究,实验结果表明该算法复杂度较低,匹配精度较高.Fingerprint matching algorithm is the core of the fingerprint algorithm,the accuracy of matching depands on the quality of the matching algorithm.For this,the fingerprint matching algorithm based on the Core points and minutiaes is given.The mathematical model of the reference point based on Core points are established with a reference fingerprint matching area on the basis of it.Fingerprint ridge line number the factor n between the reference points and minutiaes is introduced to improve the matching accuracy.And an experimental platform of fingerprint recognition algorithm is established with Visual C＋＋6.0.Experimental results show that the algorithm has a low complexity,a higher matching accuracy,a better practicability.
