Title (EN) PHYSICAL-OBJECT MEASUREMENT DEVICE AND PHYSICAL-OBJECT MEASUREMENT METHOD
(FR) DISPOSITIF DE MESURE D'OBJET PHYSIQUE ET PROCÉDÉ DE MESURE D'OBJET PHYSIQUE
(JA) 物体測定装置及び物体測定方法
Abstract:
(EN) The present invention provides a highly versatile physical-object measurement device and physical-object measurement method whereby the diameter of a columnar or cylindrical physical object can be measured with good precision. In an embodiment of the present invention, a first angle α between the imaging direction of a camera (200) and the direction normal to a white board (100) arranged along a plurality of reinforcing bars (2), and a second angle β indicating the direction of the reinforcing bars 2 as measurement objects when the imaging direction of the camera (200) is used as a reference are detected. A first distance D1 between the camera (200) and the white board (100) is also measured by a laser distance meter mounted to the camera (200). An offset amount D2 of the reinforcing bars (2) in the imaging direction of the camera (200) with respect to the first distance D1 is calculated on the basis of the measured first distance D1 and the detected first angle α and second angle β. The diameter of the reinforcing bars (2) is calculated on the basis of the focal distance of an imaging lens, the size of the diameter of the reinforcing bars 2 on an imaging sensor of the camera (200), and the distance obtained by adding the offset amount D2 to the first distance D1.
(FR) La présente invention concerne un dispositif de mesure d'objet physique hautement polyvalent, et un procédé de mesure d'objet physique, par lesquels le diamètre d'un objet physique cylindrique ou en colonne peut être mesuré avec une bonne précision. Dans un mode de réalisation de la présente invention, un premier angle α entre la direction d'imagerie d'une caméra (200) et la direction normale à un tableau blanc (100) agencé le long d'une pluralité de barres de renfort (2), et un second angle β indiquant la direction des barres de renfort (2) comme objets de mesure lorsque la direction d'imagerie de la caméra (200) est utilisée comme référence, sont détectés. Une première distance D1 entre la caméra (200) et le tableau blanc (100) est également mesurée par un élément de mesure de distance par laser monté sur la caméra (200). Une quantité de décalage D2 des barres de renfort (2) dans la direction d'imagerie de la caméra (200) par rapport à la première distance D1 est calculée sur la base de la première distance mesurée D1 et du premier angle α et du second angle β détectés. Le diamètre des barres de renfort (2) est calculé sur la base de la distance focale d'une lentille d'imagerie, de la taille du diamètre des barres de renfort (2) sur un capteur d'imagerie de la caméra (200), et de la distance obtenue par ajout de la quantité de décalage D2 à la première distance D1.
(JA) 本発明は、汎用性が高く、かつ円柱状又は円筒状の物体の径を精度よく測定することができる物体測定装置及び物体測定方法を提供する。本発明の態様において、複数の鉄筋(2)に沿って配置された白板(100)の法線方向とカメラ(200)の撮像方向とのなす第1の角度αと、カメラ(200)の撮像方向を基準にしたときの測定対象である鉄筋2の方向を示す第2の角度βとを検出する。また、カメラ(200)に搭載したレーザー距離計によりカメラ(200)と白板(100)との第1の距離D1を測定する。測定した第1の距離D1と検出した第1の角度αと第2の角度βとに基づいて、第1の距離D1に対する鉄筋(2)のカメラ(200)の撮像方向のずれ量D2を算出する。そして、第1の距離D1にずれ量D2を加算した距離と鉄筋2のカメラ(200)のイメージセンサ上の径の大きさと撮像レンズの焦点距離とに基づいて鉄筋(2)の径を算出する。
