REINFORCEMENT INSPECTION DEVICE, REINFORCEMENT INSPECTION METHOD AND PROGRAM
To provide a reinforcement inspection device, a reinforcement inspection method and a program capable of performing reinforcement inspection without photographing a reinforcement plane a plurality of times.SOLUTION: A reinforcement inspection device 1 includes a three-dimensional information acquisition part 11 that inputs a photographed image obtained by photographing with a monocular camera 2 a reinforcing bar on which an inspection sheet is laid in the longitudinal direction and three-dimensional point cloud data obtained by three-dimensional measurement of reinforcing bar by a lidar, and specifies an inspection sheet range determined by the inspection sheet from the photographed image and acquires three-dimensional point cloud data of the inspection sheet range, a plane specification part 12 that specifies a reinforcement plane to be inspected, an image conversion part 13 that converts the photographed image into a positive-pair image, a detection part 14 that detects a position information of the reinforcing bar, and a reinforcing bar diameter determination part 16 that determines a reinforcing bar diameter of the reinforcing bar based on the pixel value distribution indicated by pixel value scanning lines set for each pixel in the direction intersecting the longitudinal direction of the reinforcing bar indicated by the position information, and a measurement result information generation part 19 that generates and outputs measurement result information indicating the reinforcing bar diameter of the reinforcing bar in the inspection sheet range.SELECTED DRAWING: Figure 1
【課題】配筋面を複数回撮影することなく、配筋検査を行うことができる、配筋検査装置、配筋検査方法およびプログラムを提供する。【解決手段】配筋検査装置１は、検査シートが長手方向に敷設された鉄筋を単眼カメラ２により撮影した撮影画像と、鉄筋をライダにより三次元計測した三次元点群データとを入力し、撮影画像から検査シートにより決定される検査シート範囲を特定し、検査シート範囲の三次元点群データを取得する三次元情報取得部１１と、検査対象の配筋面を特定する平面特定部１２と、撮影画像を正対化画像に変換する画像変換部１３と、鉄筋の位置情報を検出する検出部１４と、位置情報が示す鉄筋の長手方向に交差する方向で画素ごとに設定した画素値走査線が示す画素値分布に基づいて、鉄筋の鉄筋径を判定する鉄筋径判定部１６と、検査シート範囲における鉄筋の鉄筋径を示す計測結果情報を生成して出力する計測結果情報生成部１９と、を備える。【選択図】図１
