Abstract: A bulk sorting system for sorting objects in bulk is provided. The bulk sorting system includes: at least one radiation source arranged to radiate the objects, at least one optical sensor arranged to capture reflected radiation of the objects and acquire the reflected radiation as multi- or hyperspectral data; a processing circuit configured to analyze the reflected radiation of the objects by inputting the multi- or hyperspectral data into a convolutional neural network (CNN) with at least two convolutional layers in order to either detect and classify the objects in the multi- or hyperspectral data and/or semantically segment the multi- or hyperspectral data; and a mechanical sorter configured to sort the objects according to their classification and/or segmentation using the analysis of the processing circuit such that different overlapping and/or stacked objects are separated or treated as a single group of objects.

Abstract: A method for object classification, including: guiding a continuous stream of objects from a transport mechanism directly into an unsupported path, along which the object stream is fed through a detection region; illuminating the detection region with a radiation band in a first direction; optically scanning the detection region to detect electromagnetic radiation reflected by the at least one object in the detection region by viewing the detection region along a second direction, wherein the directions have a cross-section in the detection region and form an angle relative each other of 10°-80°; analyzing the information; and classifying objects in at least two different directions based on the analysis of the transparency information from the optical scanning; wherein the step of analyzing the information from the optical scanning includes analyzing the objects based on the intensity, spread and texture of the detected radiation from the optical scanning.
