US Patent 10950124 License plate recognition

A license plate recognition and secondary image review system and processes are described. The system supplements optical character recognition with a secondary image review process that matches an acquired image with either images in a trusted database of historic confirmed identification or with fingerprint data derived from the images compared with confirmed fingerprint data from prior identifications contained in a trusted data base. The system provides an alternative to manual reviews in a selected subset of OCR identifications, while maintaining a preselected accuracy and risk of misidentification.
