发明名称 ALGORITHMIC CORRECTION OF IMAGE DISTORTION FOR FINGERPRINT IMAGING SYSTEM
摘要 A software implemented system for algorithmic correction of systematic image distortions within fingerprint imaging systems. The system 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 model, images captured by the manufactured fingerprint imaging system can be rectified to generate rectified images with relatively low amounts of distortion present. Rectification to remove distortion based on the 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, potentially enabling enhanced precision of generated images without increasing various costs of the fingerprint imaging system (or its components) generating the images.
