Zusammenfassung:To provide a method capable of precisely detecting the placement status of a cement-kneaded body in the planned placement area while simplifying on-site work.SOLUTION: The method includes: a step (a) of virtually arranging a plurality of detection virtual points in a planned placement area formed surrounded by a formwork through calculation processing; a step (b) of capturing an image of a reference marker and part of the planned placement area by a depth camera installed at a position allowing for looking down on the planned placement area; a step (c) of determining, through calculation processing, pixel virtual points based on a relative relation between a position of the reference marker on the captured image and a position of each corresponding pixel in the placement area, the pixel virtual points being the detection virtual points corresponding to the respective pixels; and a step (d) of detecting the placement status of a cement-kneaded body by comparing each value determined by each actually measured distance between each pixel virtual point obtained based on the captured image and the depth camera, with each value determined by each calculated distance being a distance between the detection virtual point corresponding to the pixel virtual point and the depth camera obtained through calculation.SELECTED DRAWING: Figure 1 【課題】現場での作業を簡素化しながらも、打設予定領域内におけるセメント混練体の打設状況を精度よく検知できる方法を提供する。【解決手段】この方法は、演算処理により型枠で囲まれてなる打設予定領域に複数の検知用仮想点を仮想的に配列する工程(a)と、打設予定領域を見下ろす位置に設置された深度カメラから基準マーカーと一部の打設予定領域とを撮像する工程(b)と、撮像画像上の基準マーカーの位置と打設予定領域内に対応する各画素の位置との相対的な関係に基づいて各画素に対応する検知用仮想点である画素仮想点を演算処理により確定する工程(c)と、撮像画像に基づいて得られる画素仮想点と深度カメラとの間の実測距離によって決定される値と、画素仮想点に対応する検知用仮想点と深度カメラとの間の計算上の距離である演算距離によって決定される値とを比較してセメント混練体の打設状況を検知する工程(d)とを有する。【選択図】図1
