Identification device, vehicle monitoring system, and vehicle monitoring method
An identification device includes a processor configured to acquire a result of determining, based on a part of an image with a moving object which does not include a face of an occupant on the moving object, whether the occupant is an identification target, and to identify the face of the occupant based on an image including the face of the occupant if the result indicates that the occupant is the identification target.
1. A vehicle monitoring system comprising:
a monitoring device, a video storage and analysis device, and a terminal device, wherein:
the monitoring device is configured to image an occupant of a vehicle and image at least a part of the vehicle and to transmit vehicle video data relating to the image of the at least the part of the vehicle to the video storage and analysis device;
the video storage and analysis device is configured to detect whether the vehicle included in the vehicle video data transmitted from the monitoring device matches a vehicle registered in advance;
the monitoring device is configured to transmit occupant video data relating to the image of the occupant to the video storage and analysis device in response to a detection result of the video storage and analysis device detecting that the vehicle included in the vehicle video data matches the vehicle registered in advance;
the video storage and analysis device is configured to identify the occupant included in the occupant video data in response to the detection result detecting that the vehicle included in the vehicle video data matches the vehicle registered in advance and the occupant video data being transmitted by the monitoring device;
the video storage and analysis device is configured to transmit the vehicle included in the matched vehicle video data and the identified occupant to the terminal device in response to the detection result detecting that the vehicle included in the vehicle video data matches the vehicle registered in advance and an identification result of the video storage and analysis device identifying the occupant; and
the terminal device is configured to display the vehicle and the occupant,
wherein, in response to the detection result detecting that the vehicle included in the vehicle video data does not match the vehicle registered in advance, the occupant video data relating to the image of the occupant is discarded.
2. The vehicle monitoring system according to claim 1 , wherein:
the video storage and analysis device is configured to detect whether the vehicle included in the vehicle video data matches the vehicle registered in advance, based on a vehicle number included in the vehicle video data.
3. The vehicle monitoring system according to claim 1 , wherein:
the video storage and analysis device is configured to detect whether the vehicle included in the vehicle video data matches the vehicle registered in advance, based on a vehicle feature included in the vehicle video data.
4. The vehicle monitoring system according to claim 1 , wherein:
the occupant video data includes a face of the occupant; and
the video storage and analysis device is configured to transmit an image relating to the face of the occupant, which is successfully identified among images included in the occupant video data.
5. The vehicle monitoring system according to claim 4 , wherein:
the image relating to the face of the occupant, which is successfully identified among images included in the occupant video data, is a one-shot image.
6. The vehicle monitoring system according to claim 5 , wherein:
the video storage and analysis device is configured to aggregate the detection result of the vehicle, the identification result of the occupant, and the one-shot image, and to transmit the detection result of the vehicle, the identification result of the occupant, and the one-shot image to the terminal device.
7. The vehicle monitoring system according to claim 1 , wherein:
a process, by which the video storage and analysis device is configured to identify the occupant included in the occupant video data in response to the detection result detecting that the vehicle included in the vehicle video data matches the vehicle registered in advance, includes collating an occupant face in the occupant video data.
8. A vehicle monitoring method implemented by a vehicle monitoring system including a monitoring device, a video storage and analysis device, and a terminal device, the vehicle monitoring method comprising:
imaging an occupant of a vehicle and imaging at least a part of the vehicle;
transmitting vehicle video data relating to an image of the at least the part of the vehicle to the video storage and analysis device;
detecting whether the vehicle included in the vehicle video data matches a vehicle registered in advance;
transmitting occupant video data relating to the image of the occupant to the video storage and analysis device in response to a detection result detecting that the vehicle included in the vehicle video data matches the vehicle registered in advance;
identifying the occupant included in the occupant video data in response to the detection result detecting that the vehicle included in the vehicle video data matches the vehicle registered in advance and the occupant video data being transmitted to the video storage and analysis device;
transmitting the vehicle included in the matched vehicle video data and the identified occupant to the terminal device in response to the detection result detecting that the vehicle included in the vehicle video data matches the vehicle registered in advance and an identification result identifying the occupant;
displaying the vehicle and the occupant on the terminal device in response to the vehicle and the identified occupant being transmit; and
in response to the detection result detecting that the vehicle included in the vehicle video data does not match the vehicle registered in advance, discarding the occupant video data relating to the image of the occupant.
9. The vehicle monitoring method according to claim 8 , wherein:
a process by which the occupant included in the occupant video data is identified in response to the detection result detecting that the vehicle included in the vehicle video data matches the vehicle registered in advance, includes collating an occupant face in the occupant video data.
