PROBLEM TO BE SOLVED: To provide a monitor system that acquires a three-dimensional shape of an object accurately in real time to thereby compare a characteristic of a two-dimensional shape or three-dimensional shape, and enables an accurate determination of whether the object is likely to be a portion of a human body or not and thus, not only greatly reduces wrong detection but also more in detail determines whether a behaviour of a person to be monitored is a predictive action leading to falling and the like.SOLUTION: A three-dimensional shape of an object is accurately acquired in real time using detection means capable of measuring a distance to a detected object for each pixel, and thereby a characteristic of a two-dimensional shape or three-dimensional shape is compared to determine whether the object is likely to be a portion of a human body.COPYRIGHT: (C)2015,JPO&INPIT【課題】物体の3次元形状を精度よく且つリアルタイムに得ることで、2次元形状または3次元形状の特徴を比較し、人の身体の部位である可能性が高いか否かの判定を高精度で行え、したがって、誤検出が大きく減少するだけではなく、落下等につながる前兆となる行動であるか否かをより詳細に判断できる監視システムを提供する。【解決手段】画素ごとに被検知物までの距離を計測可能な検知手段を用いて、物体の3次元形状を精度よく且つリアルタイムに得ることで、2次元形状または3次元形状の特徴を比較し、人の身体の部位である可能性が高いか否かの判定を行う。【選択図】図1
