Document Type and Number:
Japanese Patent JP6686649
Kind Code:
B2
Abstract:
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
