Prediction of fiber orientation in Norway spruce logs using an X-ray log scanner: A preliminary study

摘要

Previous studies have shown that a CT scanner can be used to accurately measure spiral grain in logs. However, the application of such a CT scanning system is of limited use in an industrial application because of the cost and processing time associated with CT scanning. The aim of this study was a preliminary assessment of predicting fiber orientation, an indication of spiral grain, in centerboards from Norway spruce (Picea abies) saw logs using an X-ray log scanner. The scanner is a highspeed commercial log-scanning device used to grade and sort logs based on internal quality characteristics.
