Shredder Residue characterization by Machine Vision
Person in charge: firstname.lastname@example.org
Call identifier: Plan Marshall 2.vert
Duration: 36 months (2015-2017)
Consortium: Comet Traitement, Citius Engineering.
Funding: Public Service of Wallonia
Metallurgy is a skill that Wallonia can not loose. Thus, in the context of the Marshall Plan, € 41.5 million is invested in the « Reverse Metallurgy » project which brings together different industrial and academic Walloon partners in order to allow the development of techniques that better recycle metals.
As part of this project Reverse Metallurgy, GeMMe group from the University of Liège, in collaboration with Comet Treatment and Citius Engineering, develops an acquisition bench intended in particular for characterization of metallic automotive shredder residues for recycling purposes .
This bench is the integration of a conveyor belt and various sensors:
– XRT (X-Ray Transmission) for measuring the density of the material.
– 3D to measure the shape parameters of the crushed objects.
– Hyperspectral to measure its reflectance spectrum.
These measures allow a real-time high-speed classification of the different metallic objects passing under the sensors. The major difficulties will be the synchronization of the different sensors and the calibration and real-time analysis of those measurements.
This project has real industrial prospects and particular problems will be brought to the robustness of the developed solution.
