CONCRETE COMPACTION TRACEABILITY SYSTEM
To provide a concrete compaction traceability system which allows a user to accurately grasp a compacted spot.SOLUTION: A concrete compaction traceability system comprises: an AR marker 11 which is provided on the upper surface of fresh concrete C or in the periphery of a mold frame 10; imaging means 24; a hanging member 18 which hangs a vibrator 12 in the fresh concrete C and extends; position acquisition means 26 which successively acquires a relative position of the hanging member 18 with respect to the upper surface of the fresh concrete C on the basis of an image output by the imaging means 24 and position information of the AR marker 11 in the image; position estimation means 28 which successively estimates a position of the vibrator 12 hung by the hanging member 18; and history information acquisition means 30 which acquires history information about a spot where compaction is performed by the vibrator 12.SELECTED DRAWING: Figure 1
【課題】締固めをした箇所をより高精度に把握することのできるコンクリート締固めトレーサビリティシステムを提供する。【解決手段】フレッシュコンクリートＣの上面または型枠１０の周辺に設けられたＡＲマーカー１１と、撮像手段２４と、フレッシュコンクリートＣ中の振動体１２を吊持して延び出る吊持部材１８と、撮像手段２４により出力された映像と映像中のＡＲマーカー１１の位置情報に基づいて、フレッシュコンクリートＣの上面に対する吊持部材１８の相対的な位置を継時的に取得する位置取得手段２６と、吊持部材１８に吊持された振動体１２の位置を継時的に推定する位置推定手段２８と、振動体１２による締固めを実施した箇所に関する履歴情報を取得する履歴情報取得手段３０とを備えるようにする。【選択図】図１
