BAR ARRANGEMENT MEASUREMENT APPARATUS
PROBLEM TO BE SOLVED: To provide a bar arrangement measurement apparatus which enables measurement of high versatility.SOLUTION: A white board 100 having a rectangular outer shape and reinforcing bars are captured by a camera 200 so as to be included in one image and a laser range finder that the camera 200 comprises measures a distance from the camera 200 to the white board 100. A computer 300 acquires an image captured by the camera 200 and identifies an imaging direction on the basis of a shape profile of the white board 100 included in the image. The computer 300 specifies a positional relation between the camera 200 and the white board 100 on the basis of the distance measured by the laser range finder and the identified imaging direction. According to the positional relation, a diameter of reinforcing bars 2 and 3 included in the image and a pitch therebetween are measured.SELECTED DRAWING: Figure 1
【課題】汎用性の高い測定が可能な配筋測定装置を提供する。【解決手段】矩形の外形を有する白板１００及び鉄筋を一画面に収めてカメラ２００で撮影し、かつ、カメラ２００に備えられたレーザー距離計でカメラ２００から白板１００までの距離を測定する。コンピューター３００は、カメラ２００で撮影された画像を取得し、画像に含まれる白板１００の輪郭形状に基づいて撮影方向を特定する。また、コンピューター３００は、レーザー距離計で測定された距離、及び、特定された撮影方向に基づいて、カメラ２００と白板１００との位置関係を特定する。その位置関係に基づいて画像に含まれる鉄筋２、３の径及びピッチを測定する。【選択図】図１
