ALGORITHMIC CORRECTION OF IMAGE DISTORTION FOR FINGERPRINT IMAGING SYSTEM

摘要

A software implemented system and method for algorithmic correction of systematic image distortions within fingerprint imaging systems. The system and method may implement a three dimensional geometric model of a fingerprin t imaging system to discover where a predicted configuration and the actual configuration of a system differ. By describing this difference using the geometric mode images captured by the manufactured fingerprint imaging syste m can be rectified in operational use to generate rectified images. Rectifying the images to remove distortion based on the geometric model, without physically adjusting and/or correcting the manufactured fingerprint imaging system or its components.
