Zusammenfassung:PROBLEM TO BE SOLVED: To provide an aggregation identification method that enables an aggregate classified by a plurality of kinds according to grain sizes to be automatically identified by a simple method with no intervention of a worker, an aggregate identifier, and an aggregate transportation storage unit.SOLUTION: An aggregate identification method for identifying a plurality of kinds of aggregates classified on the basis of grain sizes comprises capturing an aggregate mass consisting of aggregates dropped onto a conveyer belt with a line laser camera to acquire cross-section image data of the aggregate mass parallel with the conveyer belt transportation direction, extracting the surface shape of the aggregate mass from the cross-section image data as an irregularity line, and calculating a pitch length between adjacent troughs of the irregularity line to identify the grain size on the basis of the pitch length.SELECTED DRAWING: Figure 6 【課題】粒径により複数の種類別に分類された状態の骨材を、作業者が介在することなく簡略な方法で自動識別することの可能な骨材識別方法、骨材識別装置および骨材搬送貯蔵装置を提供する。【解決手段】粒径に基づいて分類された複数種類の骨材を識別する骨材識別方法であって、コンベヤベルト上に投下された骨材よりなる骨材塊をラインレーザーカメラにより撮像して、前記コンベヤベルトの搬送方向に平行な前記骨材塊の断面画像データを取得し、該断面画像データから前記骨材塊の表面形状を凹凸線として抽出するとともに、該凹凸線の隣り合う谷部のピッチ長を算出し、該ピッチ長に基づいて、前記骨材の粒径を識別することを特徴とする。【選択図】図6
