To provide a measuring device that can acquire pieces of point group data that have high density and have reduced variations in the interval therebetween.SOLUTION: A measuring device has: a mirror 7 that irradiates an object 11 with scan light 10 and reflects reflected light 12 from the object; a first driving unit 13 that rotates the mirror around a first axis (X-axis) parallel to the horizontal direction; a second driving unit 14 that rotates the mirror around a second axis (Y-axis) parallel to the vertical direction; and a control unit 15 that controls the first driving unit and the second driving unit and acquires data related to the shape of the object on the basis of the reflected light. The control unit 15 acquires information on the control of the second driving unit 14 on the basis of a lower limit of the rotation speed of the second driving unit at which the second driving unit 14 can rotate at equal speed and a target value of the density of the data.SELECTED DRAWING: Figure 1 【課題】高密度で間隔ムラの少ない点群データを取得可能な計測装置を提供すること。【解決手段】計測装置は、物体１１に走査光１０を照射し、物体からの反射光１２を反射するミラー７と、水平方向に平行な第１軸（Ｘ軸）周りにミラーを回転させる第１駆動部１３と、鉛直方向に平行な第２軸（Ｙ軸）周りにミラーを回転させる第２駆動部１４と、第１駆動部と第２駆動部とを制御すると共に、反射光に基づいて物体の形状に関するデータを取得する制御部１５とを有し、制御部１５は、第２駆動部１４が等速回転可能な第２駆動部の回転速度の下限値とデータの密度の目標値とに基づいて、第２駆動部１４の制御に関する情報を取得する。【選択図】図１
