Abstract
A visualization method was used in this work for the 3D morphology of internal defects in wooden products using a Philips Brilliance 16 computed tomography (CT). To obtain a high-quality 3D digital model, the original images from the CT scan were segmented to manually color the cross and vertical sections of the wooden specimen. Through coloring, the reconstructed model showed the accurate 3D morphology of internal defects, such as cracks, wormholes, and decay parts, as well as clear shapes of borer excrement, nails, bark, and wood parts of the specimen. The results suggest that this method provides precise 3D models of different types of defects in the wooden specimen. It can also accurately measure the size and angle of the defects at any position for further observation. This method can be effectively used for non-destructive testing of wooden products and wooden cultural relics and can provide accurate scales of defects and intuitive 3D models for wooden products and wooden cultural relics restoration.Keywords
