3D fibre orientation reconstruction around a knot in Douglas fir

Abstract

This work is exhibiting a new laboratory investigation method to obtain fibre 3D angle measurement of a wood piece after successive planing of the whole specimen. By combining in-plane fibre measurements through laser points measurements (using the tracheid effect) and growth layer reconstruction through image processing of RGB scans of each revealed planed faces of the douglas fir specimen, we achieve to make a full map of the 3D fibre angle of the wood piece.
