Claim 0:
1. A vehicle number identification device comprising:
a registration-number-information acquisition part configured to acquire registration number information associated with an identification media installed in a vehicle;
a number-plate-image acquisition part configured to acquire a number-plate image of the vehicle;
an OCR processing part configured to acquire OCR resultant information representing a result of an optical character recognition with respect to the number-plate image;
an estimation processing part configured to input the number-plate image into a machine-learning model and to acquire estimation result information output from the machine-learning model;
a matching determination part configured to determine whether at least two types of information out of the registration number information, the OCR resultant information, and the estimation result information indicate a same vehicle number and to identify the same vehicle number as a vehicle number of the vehicle;
a machine-learning-data generation part configured to generate machine-learning data representing an association between the vehicle number and the number-plate image when the matching determination part determines that at least two types of information out of the registration number information, the OCR resultant information, and the estimation result information indicate the same vehicle number; and
an image presentation part configured to present the number-plate image when the matching determination part determines that any combination including at least two types of information out of the registration number information, the OCR resultant information, and the estimation result information does not indicate the same vehicle number,
wherein the machine-learning-data generation part is configured to generate the machine-learning data representing an association between the vehicle number input thereto and the number-plate image.
