To provide an attitude angle derivation device and an attitude angle sensor that can detect an attitude angle with high accuracy.SOLUTION: An attitude angle derivation device includes an acquisition section, a storage section, and a processing section. The acquisition section can acquire a rotation angle related to a first coordinate system. The rotation angle is obtained from an angle sensor provided in an object. The storage section can store the rotation angle and an attitude angle related to a second coordinate system of the object. The processing section can acquire the rotation angle and the attitude angle, update the attitude angle on the basis of a temporal change of the rotation angle derived from the rotation angle, and output the updated attitude angle.SELECTED DRAWING: Figure 1 【課題】高精度の姿勢角の検出が可能な姿勢角導出装置及び姿勢角センサを提供する。【解決手段】実施形態によれば、姿勢角導出装置は、取得部、記憶部及び処理部を含む。前記取得部は、第１座標系に関する回転角を取得可能である。前記回転角は、対象物に設けられた角度センサから得られる。前記記憶部は、前記対象物の第２座標系に関する姿勢角と、前記回転角と、を記憶可能である。前記処理部は、前記回転角及び前記姿勢角を取得して、前記回転角から導出される前記回転角の時間変化に基づいて、前記姿勢角を更新して、前記更新された姿勢角を出力可能である。【選択図】図１
