Abstract

A deterioration diagnosis device including an acquisition unit that acquires sensing information including at least a captured image captured by an image capture device mounted on a moving body, driving condition information indicating driving details of the moving body, and position information corresponding to the captured image and the driving condition information; a deterioration degree analysis unit that analyzes a deterioration degree of an inspection target appearing in the captured image; and a priority ranking computation unit that computes a priority ranking of the inspection target based on deterioration degrees of the same inspection target appearing in multiple captured images identified by the position information, and the driving condition information corresponding to the identified inspection target.

Claims (40)

1. A deterioration diagnosis device comprising:

at least one memory configured to store instructions; and

at least one processor configured to execute the instructions to;

acquire, from each of a plurality of vehicles, sensing information including at least a captured image captured by an image capture device mounted on a corresponding vehicle, driving condition information indicating driving details of the corresponding vehicle, and position information corresponding to the captured image and the driving condition information;

analyze a deterioration degree of an inspection target appearing in each captured image acquired from the plurality of vehicles;

compute a single deterioration degree of the inspection target appearing in multiple captured images, which are acquired from the plurality of vehicles, identified by the position information based on analyzed deterioration degrees of the inspection target; and

compute a priority ranking of the inspection target based on the single deterioration degree of the inspection target appearing in the multiple captured images identified by the position information, and the driving condition information corresponding to the inspection target.

2. The deterioration diagnosis device according to claim 1 ,

wherein the at least one processor is configured to execute the instructions to:

identify at least hazard information which is one type of the driving condition information corresponding to the inspection target, and compute an inspection priority level of the inspection target as the priority ranking based on the computed single deterioration degree and a weighting coefficient corresponding to the hazard information.

3. The deterioration diagnosis device according to claim 1 ,

wherein the at least one processor is configured to execute the instructions to:

compute the priority ranking of the inspection target based on deterioration report information regarding the inspection target.

4. The deterioration diagnosis device according to claim 1 ,

wherein the at least one processor is configured to execute the instructions to:

identify the captured image that matches prescribed sensing conditions based on the information contained in the sensing information, and analyze the deterioration degree of the inspection target appearing in the each captured image.

5. The deterioration diagnosis device according to claim 1 ,

wherein the at least one processor is configured to execute the instructions to:

compute the single deterioration degree of the inspection target appearing in the multiple captured images based on statistical results regarding the analyzed deterioration degrees of the inspection target appearing in the multiple captured images.

6. The deterioration diagnosis device according to claim 1 ,

wherein the at least one processor is further configured to execute the instructions to:

output map information indicating an area having a high priority ranking identified based on a number of multiple inspection targets in which the deterioration degree is equal to or higher than a threshold value, and corresponding priority rankings of the multiple inspection targets.

7. The deterioration diagnosis device according to claim 1 , wherein

the driving condition information includes the driving details that indicates an occurrence of an action of the corresponding vehicle for hazard avoidance, and

the at least one processor is configured to execute the instructions to compute the priority ranking of the inspection target based on the single deterioration degree of the inspection target appearing in the multiple captured images, and presence or absence of the driving condition information corresponding to the position information of the inspection target.

8. The deterioration diagnosis device according to claim 2 ,

wherein the hazard information includes at least one of braking amount, steering wheel angle, or acceleration information.

9. A deterioration diagnosis system comprising:

an image capture device that captures an image of outside of a corresponding vehicle;

at least one memory configured to store instructions; and

at least one processor configured to execute the instructions to;
