Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a walking measuring device and a walking measuring method that can evaluate a posture of a walking part in the walking.SOLUTION: An inertial sensor 1 detects at least any one of the acceleration and angular velocity as the physical quantity for representing spatial exercise of a walking part. A vector calculation part 22 calculates a virtual vector for representing a posture of the walking part changing with the walking motion based on the physical quantity detected in the sensor. A first tilt angle calculation part 23 projects the vector in the frontal plane being a virtual plane vertical to the walking direction and a floor surface, and calculates a first tilt angle in the frontal plane of the walking part based on the projected vector.SELECTED DRAWING: Figure 4
【課題】歩行時の歩行部位の姿勢を評価することができる歩行測定装置及び歩行測定方法を提供する。【解決手段】慣性センサ1は、歩行部位の空間的な運動を表わす物理量として加速度及び角速度の少なくとも一方を検出する。ベクトル算出部22は、歩行運動に伴って変化する前記歩行部位の姿勢を表わす仮想的なベクトルを、前記センサにおいて検出された前記物理量に基づいて算出する。第1傾斜角算出部23は、歩行方向と床面に垂直な仮想の平面である前額面に前記ベクトルを射影し、当該射影したベクトルに基づいて前記歩行部位の前記前額面における第1傾斜角を算出する。【選択図】図4 |
