Summary:To provide a measurement system that is able to shorten a time required for calibration and, furthermore, enables accurate calibration.SOLUTION: This measuring system comprises: reflectors 31a, 31b, 31c attached to a robot 2; a measuring device having a laser head 41 that emits a laser beam toward the reflectors and receives light; coordinate relation acquiring means that emits a laser beam from the laser head 41 toward a reference reflection part 2c provided on a basal part 2a of the robot 2 and receives reflected light, thereby acquiring the position and direction of a measurement device coordinate system with respect to a robot coordinate system; and control means that accepts, from a robot control device, coordinate data under control of the reflectors provided at a leading end part of the robot 2, creates a control command for changing the direction of the laser head 41 by using the accepted coordinate data and the position and direction of the measurement device coordinate system with respect to the robot coordinate system, and controls the direction of the laser head 41.SELECTED DRAWING: Figure 1 【課題】キャリブレーションに要する時間を短縮することができ、しかも正確なキャリブレーションが可能となる計測システムを提供する。【解決手段】この計測システムは、ロボット2に取付けられる反射器31a,31b,31cと、該反射器に向かってレーザ光を出射し受光するレーザヘッド41を有する計測装置と、ロボット2の基部2aに設けた基準反射部2cに向かってレーザヘッド41からレーザ光を出射し反射光を受光することによりロボット座標系に対する計測装置座標系の位置および方向を取得する座標関係取得手段と、ロボット2の先端部に取付けられた反射器の制御上の座標データをロボット制御装置から受付け、受付けた座標データと、ロボット座標系に対する計測装置座標系の位置および方向とを用いてレーザヘッド41の向きを変更するための制御指令を作成し、レーザヘッド41の向きを制御するヘッド駆動制御手段とを備える。【選択図】図1
