Classification: CPC B  G | IPC B  G

Claim 0:
1. A sensor evaluation system which evaluates a sensor which is provided in a vehicle and which is used for detecting an environment around the vehicle, the sensor evaluation system comprising:
an infrastructure device installed outside the vehicle; and
an information processing device, wherein:
the infrastructure device includes an infrastructure sensor that detects the environment around the infrastructure device, and an infrastructure information processing device that performs information processing;
the infrastructure information processing device is configured to execute:
a first feature point detection process of detecting one or more feature points, each indicating a characteristic portion of the environment around the infrastructure device, based on detection information of the infrastructure sensor; and
a first feature point position calculation process of calculating first feature point position information which is information on positions of the one or more feature points detected in the first feature point detection process; and
the information processing device is configured to execute:
a second feature point detection process of detecting the one or more feature points in the environment around the vehicle based on the detection information of the sensor;
a second feature point position calculation process of calculating second feature point position information which is information on positions of the one or more feature points, detected in the second feature point detection process;
a difference calculation process of calculating a difference between the first feature point position information and the second feature point position information associated with the same one or more feature points; and
a function evaluation process of evaluating a function of the sensor based on a magnitude of the difference.
