摘　　要：近年来,文献中报道了许多指纹匹配算法。这里提出了一种新的指纹特征点匹配算法,这种算法识别速度更快,精度较高,适用于实时指纹识别系统。利用指纹的中心点来确定匹配参考点,并采用圆形匹配限制框进行匹配,提高了匹配速度和精度。对一组由扫描仪获取的指纹图像做实验,结果表明,该算法比以往算法速度更快,精度更高。Many fingerprint matching algorithms have been reported in articles in recent years. A new fingerprint minutiae matching algorithm is proposed, which is fast, accurate and suitable for the real time fingerprint identification system. In this algorithm the core point is used to determine the reference point and a round bounding box is used for matching, which improved matching speed and accuracy. Experiments done on a set of fingerprint images captured with a scanner showed that the new algorithm is faster and more accurate than the past algorithm.
