Abstract
Provided is a ranging sensor calibration system that can execute a calibration operation during travel at low cost and without adding a special configuration. This ranging sensor calibration system is provided with a plurality of ranging sensors that are installed facing at least a first direction along a direction of travel of a vehicle and a second direction that is an opposite direction to the first direction, and are configured to be able to measure a distance; and a calibration processing unit that configures the plurality of ranging sensors. The calibration processing unit is configured to calibrate the plurality of ranging sensors on the basis of a distance between a plurality of calibration targets disposed near a travel path for the vehicle, a distance between the plurality of ranging sensors, and a distance measured by each of the plurality of ranging sensors.
