Information processing device, driving diagnosis method, and storage medium
An information processing device includes: an acquisition unit that acquires travel information related to travel of a vehicle and information of regulation display that has been converted into information from a captured image of the regulation display, the image being an image captured by a camera mounted on the vehicle; a preprocessing unit that sets, when a reliability of the information of the regulation display that has been converted into information is equal to or higher than a threshold value, the information to a regulation value, and updates the regulation value at a certain time with any one of the regulation values in a certain section including the time; and a diagnosis unit that diagnoses a violation when the travel of the vehicle based on the travel information satisfies a violation condition based on the updated regulation value.
1. An information processing device, comprising:
an acquisition unit that acquires travel information related to travel of a vehicle and information of regulation display that has been converted into information from a captured image of the regulation display, the image being an image captured by a camera mounted on the vehicle;
a preprocessing unit that sets, when a reliability of the information of the regulation display that has been converted into information is equal to or higher than a threshold value, the information to a regulation value of regulation values; and updates the regulation value at a certain time with any one of the regulation values in a certain section including the certain time; and
a diagnosis unit that diagnoses a violation when the travel of the vehicle based on the travel information satisfies a violation condition based on the updated regulation value,
wherein
the regulation display is a display related to speed limit,
the information of the regulation display is the speed limit, and
the preprocessing unit updates all the regulation values in the certain section with a maximum value of the regulation values in the certain section.
2. The information processing device according to claim 1 , further comprising an extraction unit that extracts the captured image when the violation condition is satisfied.
3. The information processing device according to claim 2 , wherein the extraction unit terminates extraction of the captured image when the violation condition is no longer satisfied.
4. The information processing device according to claim 2 , wherein the extraction unit deletes the extracted captured image when a predetermined violation cancellation condition based on the travel information is satisfied.
5. A driving diagnosis method executed by a computer, the driving diagnosis method comprising:
acquiring travel information related to travel of a vehicle and information of regulation display that has been converted into information from a captured image of the regulation display, the image being an image captured by a camera mounted on the vehicle;
setting the information to a regulation value of regulation values when a reliability of the information of the regulation display that has been converted into information is equal to or higher than a threshold value;
updating the regulation value at a certain time with one of the regulation values in a certain section including the certain time; and
diagnosing a violation when the travel of the vehicle based on the travel information satisfies a violation condition based on the updated regulation value,
wherein
the regulation display is a display related to speed limit,
the information of the regulation display is the speed limit, and
the method further comprises updating all the regulation values in the certain section with a maximum value of the regulation values in the certain section.
6. A non-transitory storage medium storing a program for causing, when executed by a computer, the computer to execute:
acquiring travel information related to travel of a vehicle and information of regulation display that has been converted into information from a captured image of the regulation display, the image being an image captured by a camera mounted on the vehicle;
setting the information to a regulation value of regulation values when a reliability of the information of the regulation display that has been converted into information is equal to or higher than a threshold value;
updating the regulation value at a certain time with one of the regulation values in a certain section including the certain time; and
diagnosing a violation when the travel of the vehicle based on the travel information satisfies a violation condition based on the updated regulation value,
wherein
the regulation display is a display related to speed limit,
the information of the regulation display is the speed limit, and
the program, when executed by the computer, further causes the computer to execute updating all the regulation values in the certain section with a maximum value of the regulation values in the certain section.
