Title: | Vision-based Sorting of Medium Density Fibreboard and Grade A Wood Waste | Authors: | VERHEYEN, Maarten Beckers, Wim CLAESEN, Eric Moonen, Geert DEMEESTER, Eric |
Issue Date: | 2016 | Publisher: | IEEE | Source: | 2016 IEEE 21ST INTERNATIONAL CONFERENCE ON EMERGING TECHNOLOGIES AND FACTORY AUTOMATION (ETFA), IEEE, | Series/Report: | IEEE International Conference on Emerging Technologies and Factory Automation-ETFA | Abstract: | Over the last few years, the use of medium density fibreboard (MDF), oriented strand board (OSB) and other particleboard (grade B wood) has increased dramatically in the timber industry. This represents a major challenge for the wood recycling industry, which grinds this wood into chips to sell it to the wood chip industry. For this reason, the demand for an accurate, reliable, cheap and fast system that separates MIDF, OSB and other particleboard material from quality wood in a mixed wood waste stream is huge, as this is still performed manually in many places. This paper presents a vision-based solution for such a wood waste sorting system. A main contribution of our work is an industry-ready, performant integration of state-of-the-art computer vision and machine learning techniques into a robust wood waste sorting setup. This system has been implemented in a Belgian company, where it runs 16 hours/day and processes 7.5 tons of wood waste per hour (reaching a Technology Readiness Level of 9). The return on investment was less than one year. From an input stream with 45% - 55% of grade B wood, two output streams are generated, one which contains less than 2% quality wood and one which contains less than 5% grade B wood. | Keywords: | waste sorting; recycling; classification; computer vision; wood waste; grade A wood; MDF; OSB; particleboard | Document URI: | http://hdl.handle.net/1942/26526 | ISBN: | 9781509013142 | DOI: | 10.1109/ETFA.2016.7733546 | ISI #: | 000389524200053 | Rights: | ©2016 IEEE | Category: | C1 | Type: | Proceedings Paper |
