摘　　要：介绍了一种基于介质阻挡放电原理的新型人体指纹提取方法。讨论了这种方法的基本原理 ,分析了影响指纹提取质量的因素。在此基础上 ,提出了在大气中 ,采用高压纳秒放电技术是指纹提取质量的保证。文中给出了作者实拍的照片 ,表明用这种技术获得的指纹图像具有图像清晰、完整、对比度高的特点 。Based on the principle of dielectric barrier discharge,a new type of human's fingerprint acquisition method is introduced in this paper.The mechanism of this method and the factors of effects on fingerprint quality are discussed.And then,for getting a good fingerprint image,the high voltage nanosecond pulse discharge technology in atmosphere is adopted. As an experimental result,a number of fingerprint photos are given in the paper.The photos show that the fingerprint image acquired by this method is clear and complete,and is higher in contrast.So,the author believes that this method would be applied in fingerprint recognition technology.
