To improve transport efficiency of sediment transport by a crane with a bucket.SOLUTION: A weight prediction device (1) comprises an image acquisition part (101) to acquire the gripping state image of an object captured in the period from a gripping start to a gripping completion, and a weight prediction part (102) to predict the object weight using the prediction model (112) constructed by performing the machine-learning of the relationship between the gripping state image captured during the previous lift of the object and the lifted object weight.SELECTED DRAWING: Figure 1

    【課題】バケットを備えたクレーンによる堆積物の運搬の効率化。【解決手段】重量予測装置(1)は、把持開始から把持完了までの期間に撮影された対象物の把持中画像を取得する画像取得部(101)と、過去に行われた対象物の持ち上げの際に撮影された把持中画像と、持ち上げられた対象物の重量との関係を機械学習することにより構築された予測モデル(112)を用いて対象物の重量を予測する重量予測部(102)と、を備える。【選択図】図1
