摘要
生物识别技术中发展最成熟、运用最广泛的指纹技术的应用涉及指纹图像采集、图像处理、特征提取、特征比对与匹配等,其最基础、最重要环节是高质量指纹图像采集。光学、半导体、超声波3种常用指纹图像传感器各有优势及局限性,同时,更先进的指纹图像传感器亦在研发。主要介绍各种指纹图像传感器技术关键、性能特点,并简要介绍其应用情况及发展趋势。
Some well developed techniques, such as dactylogram image capturing and processing, characteristic abstraction,comparison and matching, are among the most widely applied ones in the biology identification. Especially high quality image acquiring techniques are the most foundational, the most important links. While new methods are under developing, photology, semiconductor and ultrasonic are still the common methods to implement dactylogram transducers, although every method has the pros and cons. The techniques in dactylogram image capturing, as well as key points and features of performance are introduced. Technique application and development trends are also briefly discussed.
