Information processing device, driving diagnosis method, and program

A driving diagnosis method in which a computer executes processes comprising:

• acquiring travel information related to travel of a vehicle and information of an object indicating regulation display that has been converted into information from a captured image of the object indicating regulation display, the image being captured by a camera mounted on the vehicle;
• identifying a missing part of the travel information based on whether conversion of the information of the object indicating regulation display fails or a reliability of a conversion of the travel information is below a threshold value;
• setting the missing part to the travel information that has been successfully converted into conversion information, wherein the conversion information is information from the captured image that is successfully converted before or after the missing part or a reliability of the conversion information is greater than or equal to the threshold value;
• setting the missing part to the conversion information comprises, when the missing part is detected, setting the missing part to the conversion information of the object indicating regulation display acquired at a preceding or succeeding position relative to a position where the travel information corresponding to the missing part was acquired;
• and
• executing a driving diagnosis of the vehicle with respect to the objecting indicating regulation display based on the conversion information and the travel information.

A non-transitory computer readable medium storing instructions that causes a computer to execute processes comprising:

• acquiring travel information related to travel of a vehicle and information of an object indicating regulation display that has been converted into information from a captured image of the object indicating regulation display, the image being captured by a camera mounted on the vehicle;
• identifying a missing part of the travel information based on whether conversion of the information of the object indicating regulation display fails or a reliability of a conversion of the travel information is below a threshold value;
• setting the missing part to the travel information that has been successfully converted into conversion information, wherein the conversion information is information from the captured image that is successfully converted before or after the missing part or a reliability of the conversion information is greater than or equal to the threshold value;
• setting the missing part to the conversion information comprises, when the missing part is detected, setting the missing part to the conversion information of the object indicating regulation display acquired at a preceding or succeeding position relative to a position where the travel information corresponding to the missing part was acquired;
• and
• executing a driving diagnosis of the vehicle with respect to the objecting indicating regulation display based on the conversion information and the travel information.
