摘　　要：指纹特征的匹配是实现指纹识别的重要环节,现有的匹配算法大多需要反复的调整每一个点来与图像模版中的点相对应,这样就加大了匹配算法的计算复杂度,因而无法满足指纹实时识别系统的要求。为此提出了通过快速确定参考、旋转和平移参数的方法,以实现指纹特征匹配算法的实时要求。实验结果表明,该特征匹配算法在满足实时性要求的前提下,其性能指标完全符合一般的商业用途。The fingerprint characteristic matching is an important link to realize fingerprint identification, and the existing matching algorithm mostly need to repeatedly adjust each point to corresponding to the point in image template, thus the computation complexity of the matching algorithm is increased and the algorithm can not meet the needs of real-time fingerprint identification system. Therefore the method of quickly determining reference, rotation and translating parameters is presented to realize the real-time requirements of fingerprint matching algorithm. The experimental results show that the performance indicators of the fingerprint matching algorithm are full accord with general commercial purposes under the premise of meeting real-time requirements.
