Monitoring device, and monitoring method
Provided is a monitoring device comprising: a control information acquisition unit that acquires control information transmitted from a control center with respect to a traffic signal; a checking unit that checks whether the state of a lighting face of a lamp of the traffic signal captured by a camera is consistent with the control information; and a notification unit that transmits a notification to a predetermined apparatus if an abnormality is detected as a result of the checking.
1. A monitoring device comprising:
one or more memories storing instructions; and
one or more processors configured to execute the instructions to:
acquire control information for controlling a traffic signal, the control information being transmitted from a control center;
check whether a state of a lighting face of a first lamp of the traffic signal matches the control information, the lighting face being imaged by a camera; and
transmit a notification to a predetermined device when an abnormality is detected as a result of the checking, wherein
the predetermined device is a signal control device, and
the notification is for changing a lighting state of a second lamp to a predetermined lighting pattern for notifying a vehicle and a pedestrian of the abnormality.
2. The monitoring device according to claim 1 , wherein the camera is installed near the second lamp installed facing the first lamp of the traffic signal.
3. The monitoring device according to claim 1 , wherein
the one or more processors are configured to execute the instructions to:
check a state of the lighting face of the first lamp of the traffic signal.
4. The monitoring device according to claim 3 , wherein
the one or more processors are configured to execute the instructions to:
check the state of the lighting face of the first lamp of the traffic signal by comparing a reference image of the lighting face of the first lamp of the traffic signal with an image of the lighting face of the first lamp of the traffic signal, the image of the lighting face being captured by the camera.
5. A monitoring device comprising:
one or more memories storing instructions; and
one or more processors configured to execute the instructions to:
acquire control information set to a traffic signal;
check whether a state of a lighting face of a first lamp of the traffic signal matches the control information, the lighting face being imaged by a camera; and
transmit a notification to a predetermined device when an abnormality is detected as a result of the checking, wherein
the predetermined device is a signal control device, and
the notification is for changing a lighting state of a second lamp to a predetermined lighting pattern for notifying a vehicle and a pedestrian of the abnormality.
6. The monitoring device according to claim 1 , wherein the notification includes a lighting color of the second lamp identified by the control information and a lighting color of the first lamp imaged by the camera.
7. A monitoring method performed by a monitoring device and comprising:
acquiring control information for controlling a traffic signal, the control information being transmitted from a control center;
checking whether a state of a lighting face of a first lamp of the traffic signal matches the control information, the lighting face being imaged by a camera; and
transmitting a notification to a predetermined device when an abnormality is detected as a result of the checking, wherein
the predetermined device is a signal control device, and
the notification is for changing a lighting state of a second lamp to a predetermined lighting pattern for notifying a vehicle and a pedestrian of the abnormality.
8. The monitoring device according to claim 5 , wherein the notification includes a lighting color of the second lamp identified by the control information and a lighting color of the first lamp imaged by the camera.
9. The monitoring device according to claim 1 , wherein the predetermined lighting pattern includes all-red lighting in which the lighting color of both the first lamp and the second lamp are red or blinking light.
