Abstract
A person specifying device includes an authentication unit configured to acquire a captured image capturing a person boarding a moving vehicle, to perform a matching determination as to whether or not the person reflected in the captured image matches a pre-registered person, and to generate person-specifying information representing the person determined via the matching determination; and an authentication-interval-updating unit configured to update a time interval for performing the matching determination to be shorter when failing to achieve a success frequency of authentication above a desired value via the matching determination.
Claims9
A person specifying device comprising:
- a memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- acquire a captured image capturing a person boarding a moving vehicle,
- perform a matching determination as to whether or not the person reflected in the captured image matches a pre-registered person,
- generate person-specifying information representing the person determined via the matching determination;
- and
- update a time interval for performing the matching determination to be shorter when failing to achieve a success frequency of authentication above a desired value via the matching determination.
A person specifying device comprising:
- a memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- perform a matching determination as to whether or not a person reflected in a captured image obtained from an imaging device matches a pre-registered person,
- generate person-specifying information representing the person determined via the matching determination;
- and
- update a time interval for performing the matching determination to be shorter when failing to achieve a success frequency of authentication above a desired value via the matching determination.
A person specifying method comprising:
- acquiring a captured image capturing a person boarding on a moving vehicle;
- performing a matching determination as to whether or not the person reflected in the captured image matches a pre-registered person;
- generating person-specifying information representing the person determined via the matching determination;
- and
- updating a time interval for performing the matching determination to be shorter when failing to achieve a success frequency of authentication above a desired value via the matching determination.
A storage medium configured to store a program causing a computer to:
- acquire a captured image capturing a person boarding a moving vehicle,
- perform a matching determination as to whether or not the person reflected in the captured image matches a pre-registered person,
- generate person-specifying information representing the person determined via the matching determination;
- and
- update a time interval for performing the matching determination to be shorter when failing to achieve a success frequency of authentication above a desired value via the matching determination.
