BAR ARRANGEMENT INSPECTION DEVICE, BAR ARRANGEMENT INSPECTION METHOD AND PROGRAM
To provide a reinforcing bar arrangement inspection device capable of preventing inspection omission of reinforcing bars even if occlusion occurs in a photographed image of a structure in which the reinforcing bars are arranged in multiple tiers of planes.SOLUTION: A bar arrangement inspection device 1 includes: a three-dimensional information acquisition unit 11 that inputs photographic images taken continuously from a plurality of photographing angles of an inspection area, which is a structure in which reinforcing bars are arranged on multiple tiers of planes, and acquires three-dimensional information of the structure; a three-dimensional information reconstruction unit 12 that reconstructs three-dimensional information of the structure; a plane identifying unit 13 that identifies each of multiple tiers of planes in the structure using the reconstructed three-dimensional information; an image conversion unit 14 that converts the photographed image of the structure into a directly facing image that is directly facing the structure; a position detection unit 15 that detects position information of the reinforcing bars in each of multiple tiers of planes using the directly facing image; and an occlusion determination unit 16 that determines which reinforcing bars in the lower tier are hidden by the reinforcing bars in the upper tier based on the position information of the reinforcing bars in the upper tier plane and the position information of the reinforcing bars in the lower tier plane.SELECTED DRAWING: Figure 1
【課題】複数段の平面のに鉄筋が配筋された構造体の撮影画像にオクルージョンが発生しても鉄筋の検査漏れを防止することができる配筋検査装置を提供する。【解決手段】配筋検査装置１は複数段の平面に鉄筋が配筋された構造体である検査領域を複数の撮影角度から連続して撮影された撮影画像を入力し、構造体の三次元情報を取得する三次元情報取得部１１と、構造体の三次元情報を再構成する三次元情報再構成部１２と、再構成された三次元情報を用いて構造体における複数段の平面をそれぞれ特定する平面特定部１３と、構造体の撮影画像を構造体に正対化した正対化画像に変換する画像変換部１４と、正対化画像を用いて複数段の平面のそれぞれにおける鉄筋の位置情報を検出する位置検出部１５と、上段の平面における鉄筋の位置情報と下段の平面における鉄筋の位置情報に基づいて、上段の鉄筋により隠される下段の鉄筋を判定するオクルージョン判定部１６を備える。【選択図】図１
