Zusammenfassung: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 fingerprint imaging system to discover where a configuration prescribed by a conceptual fingerprint imaging system and an actual configuration of a manufactured fingerprint imaging system differ. By describing this difference using the geometric model, images captured by the manufactured fingerprint imaging system can be rectified in operational use to generate rectified images with relatively low amounts of distortion present. 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, may enable the fingerprint imaging system to be manufactured with relatively lower tolerances without degrading a precision of the images generated by the system. This may enable an enhancement in the precision of generated images without increasing a cost (e.g., time costs, monetary costs, etc.) of the fingerprint imaging system (or its components) generating the images.
