Summary:PROBLEM TO BE SOLVED: To provide a concrete installation height control method capable of efficiently finishing a top face of installed concrete at an accurate height.SOLUTION: At least three reference points 1f with a known offset distance between each other around a top face of a region to which concrete is installed is disposed. Pictures are shot by a digital camera 2 from two different positions so that these reference points appear in the pictures. Respective shooting positions are identified from the reference points shot on the pictures. Concrete is installed and the top face is leveled, while the top face of the installed concrete is photographed from two different positions and a top face position that is the top face height is calculated by a computer 3 based on the pictures. This position is compared with a set planned finish surface and a position corresponding to the top face of the installed concrete is projected by a projection device 5 so that positions higher or lower than the calculated height of the top face can be identified.SELECTED DRAWING: Figure 1 【課題】打設したコンクリートの上面を効率よく正確な高さに仕上げることができるコンクリート打設高さの管理方法を提供する。【解決手段】 コンクリートを打設しようとする領域の上面の周囲に、互いの離隔距離が知られた３点以上の基準点１ｆを設置する。これらの基準点を写し込むように、２つの異なる位置からデジタルカメラ２で画像を撮影し、撮影された画像に写し込まれた基準点の位置からそれぞれの撮影位置を特定する。コンクリートを打設して上面を均すとともに、打設したコンクリートの上面を２つの異なる位置から撮影し、撮影した画像から上面の位置すなわち上面の高さをコンピュータ３で演算する。この位置を設定された計画仕上げ面と対比し、演算された前記上面の高さが、計画仕上げ面の高さより高い位置と計画仕上げ面の高さより低い位置とが識別が可能となるように、投影装置５によって打設したコンクリートの上面に位置を対応させて投影する。【選択図】図１
