Imported logs are a high-risk product that poses a significant threat of carrying harmful organisms inside,which can lead to severe ecological damage in China.The increasing demand for log imports has made it incredibly challenging to inspect and quarantine them,creating a severe contradiction between the clearance efficiency and quarantine capacity of log products.The Manzhouli Railway Port,the largest land port in Yanbian,China,is responsible for customs clearance and quarantine of a large volume of log products.However,the volume and quantity of imported logs are large and pest infection often occur inside the logs,thus existing methods cannot efficiently and accurately detect pest situation.To address this issue,we have conducted comprehensive research on the detection methods of log pests domestically and internationally.Consequently,we have designed a log pest detection system based on CT(Computed Tomography)imaging technology,which can significantly improve the efficiency of log pest detection,compress the overall clearance time,and have tremendous industrial promotion and application value.
