| 摘要 | A method for analyzing objects depending on their electromagnetic properties. The method including the steps of conveying the objects to be analyzed on a conveyer belt; scanning the electromagnetic properties of the objects and the conveyer belt by an electromagnetic sensor, wherein the electromagnetic properties of the conveyer belt are dependent on metallic contaminants which are stuck in the conveyer belt; generating belt properties data representing the electromagnetic properties of the conveyer belt, and analyzing the objects according to the scanned electromagnetic properties and the belt properties data. This has the benefits that the electromagnetic properties of the conveyer belt are considered when distinguishing between metallic and non-metallic objects which have to be sorted. This way, the objects which got stuck in the conveyer belt over time, may influence a sorting less, which may improve sorting results. Further, an apparatus for executing such a method. | ||

| 主权项 | 1. A method for analyzing objects depending on their electromagnetic properties, the method comprising: conveying objects to be analyzed on a conveyer belt; scanning electromagnetic properties of the objects and the conveyer belt by an electromagnetic sensor; generating belt properties data representing the electromagnetic properties of the conveyer belt, said belt properties data comprising information regarding the electromagnetic properties of the conveyer belt that are dependent on metallic contaminants which are stuck in the conveyer belt; determining a difference between previously generated electromagnetic properties of the belt and current electromagnetic properties of the belt; analyzing the objects according to the scanned electromagnetic properties and the belt properties data; and identifying a metallic contaminant as stuck in the conveyer belt only after it has been detected more than one time at a same position on the conveyor belt, and updating the belt properties data with said metallic contaminant identified as stuck in the conveyor belt. | ||
