Abstract

The invention provides an information processing device, a driving diagnosis method and a computer-readable non-transitory recording medium. The information processing device includes an acquisition unit that acquires travel information associated with travel of a vehicle and information on whether or not a target is identified from a captured image captured by a camera mounted on the vehicle, a preprocessing unit that updates information indicating that the target is identified to the information indicating that the target is not identified even when the information indicating that the target is not identified is included in the information acquired within a certain section including a certain time, and a diagnosis unit that diagnoses, for each time, that an event to be noted has occurred when the information indicating that the target is identified and a detection condition is satisfied, the detection condition being based on a form of the target and the travel information.

Description

Information processing device, driving diagnosis method, and computer-readable non-transitory recording medium Technical Field The invention relates to an information processing device, a driving diagnosis method, and a program. Background Japanese patent application laid-open No. 2021-118002 discloses a vehicle distance measuring method for measuring an inter-vehicle distance based on a vehicle image. The method for measuring the distance between vehicles includes a step of acquiring a running image captured by a camera of a first vehicle during running, a step of detecting a second vehicle from the acquired running image, a step of detecting a first feature point of a second vehicle region from a first frame corresponding to a frame in which the second vehicle is detected before the frame in which the second vehicle is not detected, out of a plurality of frames constituting the running image, if the second vehicle is not detected from the running image, a step of detecting a second feature point in the second frame corresponding to the current frame by tracking the detected first feature point, a step of calculating feature point change values of the first feature point and the second feature point, and a step of calculating the distance from the camera of the first vehicle to the second vehicle based on the calculated feature point change values. Disclosure of Invention In the case of performing driving diagnosis by a server or the like outside the vehicle, in the conventional technique, it is necessary to transmit image data from the vehicle to the server, and a burden on a communication circuit is large. The purpose of the present invention is to provide an information processing device, a driving diagnosis method, and a program that can suppress traffic when driving diagnosis is performed outside a vehicle. The information processing apparatus according to claim 1 includes an acquisition unit that acquires travel information related to travel of a vehicle and information indicating whether or not a target is identified from a captured image captured by a camera mounted on the vehicle, a preprocessing unit that updates information indicating that the target is identified even when the information indicating that the target is not identified is included in the information acquired within a certain section including a certain time, and a diagnosis unit that diagnoses that an event that should be noted has occurred when the information indicating that the target is identified is present and a detection condition is satisfied for each time, the detection condition being based on a form of the target and the travel information. In the information processing apparatus according to claim 1, the acquisition unit acquires travel information related to travel of the vehicle and information on whether or not a target is recognized from a captured image captured by a camera mounted on the vehicle. Here, the target is, for example, a preceding vehicle, a traffic signal, or the like. When the information indicating that the target is recognized is included in the information acquired within a certain period including a certain time, the preprocessing unit updates the information to the information indicating that the target is recognized even if the information indicating that the target is not recognized is included at the certain time. The diagnosis unit diagnoses that an event to be noted has occurred when information indicating that the target is recognized and a detection condition based on the form of the target and the travel information is satisfied is present for each time. Here, events to be noted are, for example, that the inter-vehicle distance is being shortened, that a vehicle is significantly delayed with respect to a preceding vehicle at the start, that the vehicle is not stopped in spite of a red light signal, and the like. The condition based on the form and the travel information of the target is a condition defined for diagnosing the form and the travel information of the use target in which the event to be noted has occurred. In this information processing apparatus, traveling information related to traveling of a vehicle and information on whether or not a target is recognized from a captured image captured by a camera mounted on the vehicle are acquired. Thus, according to the information processing apparatus, the traffic volume in the case of performing driving diagnosis outside the vehicle can be suppressed.
