Claim 2:
3. A vehicle number identification method comprising the steps of:
acquiring registration number information associated with an identification media installed in a vehicle;
acquiring a number-plate image of the vehicle;
acquiring OCR resultant information representing a result of an optical character recognition with respect to the number-plate image;
inputting the number-plate image into a machine-learning model and thereby acquiring estimation result information output from the machine-learning model;
upon determining 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, identifying the same vehicle number as a vehicle number of the vehicle;
generating machine-learning data representing an association between the vehicle number and the number-plate image when it is determined 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;
presenting the number-plate image when it is determined 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; and
generating the machine-learning data representing an association between the vehicle number input thereto and the number-plate image.
