摘　　要：利用工业CT对三组原木进行扫描,并通过VGStudioMAX软件将扫描数据进行三维重建,检测原木内部缺陷。结果表明:原木的三维重建体模型能反映出缺陷在原木中的三维空间分布情况,对原木截面的虚拟剖切,可直观了解缺陷的形状、位置和分布,精确获知缺陷的大小,实现优质和珍贵原木的利用率及利用价值最大化。Three log samples were scanned with an industrial CT scanner.The CT scanning data were reconstructed in three-dimension by VGStudio MAX software in order to detect interior defects of the log samples.The results showed that the reconstructed volume model of the logs could reveal three-dimensional distribution of the log defects.Therefore,shape and location of the defects could be observed intuitively by virtual log sawing,resulting in precisely measured size of the defects.Yield of high quality lumber and value of precious logs could be maximized.
