CALIBRATION METHOD OF RADAR DEVICE, RADAR DEVICE, MONITORING SYSTEM, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To simply and inexpensively perform calibration work in a brief period of time without performing operation regulation of train or traffic regulation of road on a traffic road of an object to be monitored.

SOLUTION: When installing a plurality of radar devices 10 monitoring a railroad crossing 51 where the railroad 50 and the road are intersected, the position of the railroad 50 is recognized by actually measuring a moving trajectory of the trains 52 traveling on the railroad 50 with the individual radar devices 10, and the calibration processing generating a conversion matrix 71 to convert the measurement data of the obstacle measured by a local coordinate system 10a of the radar device 10 into a traffic road coordinate system 50a of the side of the railroad 50 is autonomously performed in the interior of the individual radar devices 10. The calibration work can be simply and inexpensively performed in the brief period of time without requiring operation regulation of the railroad 50 to place the target of the reflector etc for calibration in the railroad crossing 51, or without increasing man-hour or period of time for calibration work even if the number of installations of the radar devices is increased.
