Automatic and Fast Testing of Wood Density Based on Computed Tomography

In this paper, we apply computed tomography (CT) technology for log nondestructive testing and calculate the CT number range of different log tomography slices in statistic method, then the parameters of CT window level and window width in log testing procedure were set. Thus it provides a fast operation procedure in the log nondestructive testing based on CT. Because of the linear relationship between wood density and CT number the fitting linear formula between CT number and wood density was calculated. Therefore a new method is provided in the nondestructive testing of log defect and wood density.
