RISK DETERMINATION METHOD, RISK DETERMINATION DEVICE, RISK DETERMINATION SYSTEM, AND RISK OUTPUT DEVICE

摘要

In a risk determination method: moving body information, in which accompanying information that indicates the current position of a moving body and a current-position image that indicates a situation around the moving body at the current position are included in correspondence to each other, is obtained; and, if risk occurrence information corresponding to the current position indicated in the accompanying information included in the moving body information is not stored in a risk occurrence information manager and risk occurrence information corresponding to a position other than the current position is stored in the risk occurrence information manager, a degree of risk at the current position is determined on the basis of a similarity between the current-position image included in the moving body information and a risky-position image included in at least one piece of risk occurrence information stored in the risk occurrence information manager.

1. A risk determination method used in a risk determination system that manages a degree of risk at a position at which a moving body is positioned, the risk determination system including a risk occurrence information manager that stores at least one piece of risk occurrence information, in which risky-position information that indicates a risky position at which a risky incident occurred and first sensor information that indicates a situation in which the risky incident occurred at the risky position are included in correspondence to each other, the method comprising:
obtaining moving body information, in which current position information that indicates a current position of the moving body and second sensor information that indicates a situation around the moving body at the current position are included in correspondence to each other; and determining, if the risk occurrence information corresponding to the current position indicated in the current position information included in the moving body information is not stored in the risk occurrence information manager and the risk occurrence information corresponding to a position other than the current position is stored in the risk occurrence information manager, a degree of risk at the current position on a basis of a similarity between the second sensor information included in the moving body information and the first sensor information included in the at least one piece of risk occurrence information stored in the risk occurrence information manager.
