Detection Of Log Internal Defect Using X-ray Scanner

The paper is based on the project of "Detect of Log Internal Defect and Shape using Numerical Control Laser and Computer Frequency Distinguish System". The research content is detect of log internal defect (such as knobs ,internal decay ,hollow ,etc.) and shape by using X-ray to penetrate the log . The absorb of X-ray between log internal defect and log internal xylem is different .so the X-ray photograph is different .If we can get the several side X-ray photograph of log .and input the photograph into computer to digital image process . Then we can get the data and the location of log internal defect .At the same time .there are some important auxiliary effect for log machining .The system software is designed by Visual C++6.0 and model technology, based on Windows operating system. It provides the good theory and application foundation for industrial popularization of log internal defect's automatic detection. The system applies itself to resolve the key problems in computer image processing and simulate reappear technology, taking full advantage of exiting equipment. After the experiment of sample log was carried out .the software is correct and accurate . To distinguish the log internal defect by X-ray scanner provide the essential theory premise and technology for the design and application of wood flaw detecting and discerning.
