| description | To provide a selecting device that selects broken fragments according to a content ratio of added metal and that easily attains to a selection rate close to an intended selection rate.SOLUTION: In a selecting device 1, a camera 13 acquires surface information associated with a surface shape of a broken fragment. An image processing part 24 calculates, based upon the acquired surface information, a wrinkle ratio which is a ratio of a wrinkle part on a surface of the broken fragment. A distribution acquisition part 26 acquires a distribution of wrinkle ratios. A threshold calculation part 28 calculates, based upon the distribution that the distribution acquisition part 26 acquires, a wrinkle ratio threshold so that a selection ratio of broken pieces reaches a predetermined value. A selection control part 25 compares the wrinkle ratio threshold that the threshold calculation part 28 calculates with the wrinkle ratio that the image processing part 24 calculates. A selection part 15 selects broken fragments based upon a result of the comparison made by the selection control part 25.SELECTED DRAWING: Figure 1
【課題】添加金属の含有割合に応じて破砕片を選別する選別装置において、意図した選別率に近い選別率を容易に実現する。【解決手段】選別装置１において、カメラ１３は、破砕片の表面形状に関する表面情報を取得する。画像処理部２４は、取得された表面情報に基づいて、破砕片の表面のうち皺が生じている部分の割合である皺割合を算出する。分布取得部２６は、皺割合の分布を取得する。閾値算出部２８は、分布取得部２６が取得した分布に基づいて、破砕片の選別率が所定値となるように皺割合閾値を算出する。選別制御部２５は、閾値算出部２８が算出した皺割合閾値と、画像処理部２４が算出した皺割合と、を比較する。選別部１５は、選別制御部２５が比較した結果に基づいて、破砕片を選別する。【選択図】図１ |
