To appropriately evaluate a walking motion without being affected by a change in a walking speed, etc.SOLUTION: Distance measurement data indicating a distance from a distance measuring sensor to an object in the periphery is acquired, and an object that satisfies an assumed size of a leg is extracted from the distance measurement data as a leg candidate. Based on a change in the coordinates of the leg candidate, a stance phase and a swing phase are distinguished, and a pair of the stance phase and the swing phase indicating the stance phase and the swing phase following the stance phase is acquired. Then, from the pair of the stance phase and the swing phase, and the stance phase in the vicinity, a pedestrian center is calculated, and from a change in the calculated pedestrian center, a walking track is acquired.SELECTED DRAWING: Figure 4

    【課題】歩行速度などの変化に影響されずに的確に歩行動作の評価ができるようにする。【解決手段】測距センサから周囲の物体までの距離を示す測距データを取得し、測距データから、想定される脚のサイズを満たす物体を脚候補として抽出する。そして、脚候補の座標の変化に基づいて、立脚期と遊脚期を区別し、立脚期とその立脚期に続いた遊脚期とを示す立脚・遊脚ペアを取得する。その後、立脚・遊脚ペアとその近傍の立脚とから歩行者中心を算出して、算出した歩行者中心の変化から歩行軌跡を得る。【選択図】図4
