Abstract
This calibration system includes: a moving body that moves within a predetermined region and generates a vibration signal; a vibration detection means, being provided within the predetermined region, for detecting a vibration signal generated in the predetermined region; a signal analysis means for analyzing the vibration signal detected by the vibration detection means, and calculating a position on the vibration detection means where the vibration detection means detects the vibration signal; and an association means for calibrating the vibration detection means at a predetermined timing by associating the position on the vibration detection means where the vibration detection means detects the vibration signal with a position in the predetermined region, based on a generation position and a generation time of the vibration signal generated by the moving body and the position on the vibration detection means where the vibration detection means detects the vibration signal and a detection time thereof.
