1. A non-transitory computer-readable storage medium storing a computer program that makes a computer execute:
- obtaining a first image by photographing identification information of a mobile object;
executing a character recognition process on the first image to obtain a plurality of candidates of a first character recognition result;
determining recognition accuracy of all of the candidates;
registering, all of the candidates, when the recognition accuracy of all of the candidates is lower than a predetermined level;
displaying all of the candidates registered simultaneously on a display unit;
obtaining a second image by photographing identification information of a second mobile object;
executing a character recognition process on the second image to obtain a second character recognition result whose recognition accuracy is higher than the predetermined level;
comparing each of the registered candidates with the second character recognition result to determine a matching candidate that matches the second character recognition result; and
switching a display on the display unit from all of the displayed candidates to the matching candidate.

Abstract
A method, device and computer program for mobile object information management program includes obtaining a first image by photographing identification information of a mobile object, executing character recognition process on the first image to obtain a first character recognition result, determining accuracy of the first character recognition result, registering, as the identification information corresponding to the mobile object, a plurality of first character recognition results, for each of which the accuracy is determined as low, and outputting the first character recognition results registered.

5. A mobile object information management device comprising:
-
a photographing unit that obtains a first image by photographing identification information of a first mobile object and, after obtaining the first image, obtains a second image by photographing identification information of a second mobile object; a character recognizing unit that executes character recognition processing on the first image to obtain a plurality of candidates of a first character recognition result and executes character recognition processing on the second image to obtain a second character recognition result whose recognition accuracy is higher than a predetermined level; an accuracy determining unit that determines recognition accuracy of all of the candidates; a recognition result registering unit that registers all of the candidates, when the recognition accuracy of all of the candidates is lower than the predetermined level; a character recognition result output unit that simultaneously displays all of the candidates registered; and a match determining unit that compares each of the registered candidates with the second character recognition result to determine a matching candidate that matches the second character recognition result, wherein the character recognition result output unit switches a display from all of the displayed candidates to the matching candidate. - View Dependent Claims (6, 7, 8)

13. A mobile object information management system comprising:
-
a photographing unit that obtains a first image by photographing identification information of a first mobile object and, after obtaining the first image, obtains a second image by photographing identification information of a second mobile object; a character recognizing unit that executes character recognition processing on the first image to obtain a plurality of candidates of a first character recognition result and executes character recognition processing on the second image to obtain a second character recognition result whose recognition accuracy is higher than a predetermined level; an accuracy determining unit that determines recognition accuracy of all of the candidates; a recognition result registering unit that registers the candidates, when the recognition accuracy of all of the candidates is equal to or lower than the predetermined level; a character recognition result output unit that simultaneously displays all of the candidates registered; and a match determining unit that compares each of the registered candidates with the second character recognition result to determine a matching candidate that matches the second character recognition result, wherein the character recognition result output unit switches a display from all of the displayed candidates to the matching candidate.

14. A mobile object information management method comprising:
-
obtaining a first image of a first mobile object; recognizing characters on the first image to obtain a plurality of candidates of a first character recognition result; displaying all of the candidates on a display unit; obtaining a second image of a second mobile object; recognizing characters on the second image to obtain a second character recognition result whose recognition accuracy is higher than a predetermined level; comparing each of the registered candidates with the second character recognition result to determine a matching candidate that matches the second character recognition result; and switching a display on the display unit from all of the displayed candidates to the matching candidate.
