To accurately perform calibration on the relative positions and attitudes of a plurality of sensors sensing space information regardless of the types and sensing ranges of the sensors.SOLUTION: The relative positional relationship between a first sensor and a second sensor measuring space information is calculated, based on third sensor data obtained by a third sensor that measures three-dimensional information on a calibration object arranged in at least part of measurement ranges of the first sensor and the second sensor, and first sensor data and second sensor data obtained by the first sensor and the second sensor, respectively.SELECTED DRAWING: Figure 6 【課題】空間情報をセンシングする複数のセンサの相対位置・姿勢に関するキャリブレーションを各センサの種類やセンシング範囲等にかかわらず高精度に行えるようにする。【解決手段】空間情報を測定する第１センサ及び第２センサのそれぞれの測定範囲の少なくとも一部に配置されたキャリブレーション物体の3次元情報を測定する第３センサにより得られた第３センサデータと、前記第１センサ及び前記第２センサによりそれぞれ得られた第１センサデータ及び第２センサデータとに基づいて、前記第１センサと前記第２センサとの相対位置関係が算出される。【選択図】図６
