In previous work, we presented a novel design of an optical belt sorter, which includes an area scan camera instead of a line scan camera. Line scan cameras, which are well-established in optical belt sorting, only allow for a single observation of each particle. Using multitarget tracking, the data of the area scan camera can be used to derive a part of the trajectory of each particle. The knowledge of the trajectories can be used to generate accurate predictions as to when and where each particle passes the separation mechanism. Accurate predictions are key to achieve high quality sorting results. The accuracy of the trajectories and the predictions heavily depends on the motion model used. In an evaluation based on a simulation that provides us with ground truth trajectories, we previously identified a bias in the temporal component of the prediction. In this paper, we analyze the simulation-based ground truth data of the motion of different bulk materials and derive models specifically tailored to the generation of accurate predictions for particles traveling on a conveyor belt. The derived models are evaluated using simulation data involving three different bulk materials. The evaluation shows that the constant velocity model and constant acceleration model can be outperformed by utilizing the similarities in the motion behavior of particles of the same type.<\/jats:p>","DOI":"10.1515\/auto-2019-0134","type":"journal-article","created":{"date-parts":[[2020,5,26]],"date-time":"2020-05-26T14:10:19Z","timestamp":1590502219000},"page":"239-255","source":"Crossref","is-referenced-by-count":1,"title":["Predictive tracking with improved motion models for optical belt sorting"],"prefix":"10.1515","volume":"68","author":[{"given":"Florian","family":"Pfaff","sequence":"first","affiliation":[{"name":"Intelligent Sensor-Actuator-Systems Laboratory (ISAS) , Karlsruhe Institute of Technology (KIT) , Karlsruhe , Germany"}]},{"given":"Christoph","family":"Pieper","sequence":"additional","affiliation":[{"name":"Department of Energy Plant Technology (LEAT) , Ruhr-Universit\u00e4t Bochum (RUB) , Bochum , Germany"}]},{"given":"Georg","family":"Maier","sequence":"additional","affiliation":[{"name":"Fraunhofer IOSB , Fraunhofer Institute of Optronics, System Technologies and Image Exploitation , Karlsruhe , Germany"}]},{"given":"Benjamin","family":"Noack","sequence":"additional","affiliation":[{"name":"Intelligent Sensor-Actuator-Systems Laboratory (ISAS) , Karlsruhe Institute of Technology (KIT) , Karlsruhe , Germany"}]},{"given":"Robin","family":"Gruna","sequence":"additional","affiliation":[{"name":"Fraunhofer IOSB , Fraunhofer Institute of Optronics, System Technologies and Image Exploitation , Karlsruhe , Germany"}]},{"given":"Harald","family":"Kruggel-Emden","sequence":"additional","affiliation":[{"name":"Mechanical Process Engineering and Solids Processing (MVTA) , Technical University Berlin , Berlin , Germany"}]},{"given":"Uwe D.","family":"Hanebeck","sequence":"additional","affiliation":[{"name":"Intelligent Sensor-Actuator-Systems Laboratory (ISAS) , Karlsruhe Institute of Technology (KIT) , Karlsruhe , Germany"}]},{"given":"Siegmar","family":"Wirtz","sequence":"additional","affiliation":[{"name":"Department of Energy Plant Technology (LEAT) , Ruhr-Universit\u00e4t Bochum (RUB) , Bochum , Germany"}]},{"given":"Viktor","family":"Scherer","sequence":"additional","affiliation":[{"name":"Department of Energy Plant Technology (LEAT) , Ruhr-Universit\u00e4t Bochum (RUB) , Bochum , Germany"}]},{"given":"Thomas","family":"L\u00e4ngle","sequence":"additional","affiliation":[{"name":"Fraunhofer IOSB , Fraunhofer Institute of Optronics, System Technologies and Image Exploitation , Karlsruhe , Germany"}]},{"given":"J\u00fcrgen","family":"Beyerer","sequence":"additional","affiliation":[{"name":"Fraunhofer IOSB , Fraunhofer Institute of Optronics, System Technologies and Image Exploitation , Karlsruhe , Germany"}]}],"member":"374","published-online":{"date-parts":[[2020,3,25]]},"reference":[{"key":"2023033110290206683_j_auto-2019-0134_ref_001_w2aab3b8d145b1b7b1ab2ab1Aa","doi-asserted-by":"crossref","unstructured":"J.
