Wood Fingerprints

Published: 5 June 2014

My research deals with wood fingerprints and how to track sawn wood products through an industrial process using cameras, says Tobias Pahlberg in his licentiate thesis. The possibility to identify individual wood products comes from the trees’ biological variation, where the DNA, environment and breakdown process creates a unique appearance for every board. The flow speed in wood industries is usually very high and with a high degree of automation. Wood fingerprints can be used together with automatic inspection, which in its turn can bring vital feedback on process parameters.
