本文提出了一种应用X射线无损检测技术检测原木内部缺陷的方法。检测过程中应用计算机数字图象处理技术对原始的X射线图象进行中值滤波、图象锐化,使得处理后的图象更加清晰,图象中的目标易于人眼识别。在中文WINDOWS平台上开发编制软件,界面友好,使用方便,操作简单。实验结果表明这种方法行之有效。
A new method of X-Ray Non Destructive Detection for a log is presented in the paper. Computer Digital Image Processing techniques is used in the processing of detection. With fast median noise filtering, picture enhancement and differentiation, edge detection, the X-Ray pictures are much more clear, the defects in the picture are easy to be recognized by people. Digital Image Processing system is programmed in window system, the interface is clear and easy to use for operators. The experimental results show this method is effective.
