Zusammenfassung:To accurately estimate the amount of explosives at a drilling position.SOLUTION: An analysis device includes an acquisition unit that acquires a predetermined support pattern for a face position of the natural ground to be excavated through a tunnel, and a panoramic face image photographed by a camera of the face position, and acquires, for each drilling position for loading explosives for the tunnel face, sensor data obtained when drilling a hole at the drilling position and a partial image of the panoramic face image including the drilling position; and an estimation unit that estimates the amount of explosives at each drilling position using a pre-trained model that inputs the support pattern, the sensor data, and the partial image, and outputs the amount of explosives at the drilling position.SELECTED DRAWING: Figure 2 【課題】削孔位置の装薬量を精度よく推定することを目的とする。【解決手段】解析装置は、トンネルの掘削対象となる地山の切羽位置に対して予め決定された支保工パターンと、前記切羽位置をカメラで撮影した切羽全景画像を取得すると共に、トンネル切羽用の装薬のための削孔位置毎に、前記削孔位置の削孔を行う際に得られたセンサデータと、前記切羽全景画像の内の前記削孔位置を含む部分画像とを取得する取得部と、前記削孔位置毎に、前記支保工パターン、前記センサデータ、及び前記部分画像を入力とし、前記削孔位置の装薬量を出力する予め学習されたモデルを用いて、前記削孔位置の装薬量を推定する推定部と、を含む。【選択図】図2
