Optimization Study of the Velocity of a Cargo Moving Stage for Container Inspection System

The global market of Container Inspection System (CIS) is worth of a few billions dollar whereas a small number of companies such as Varian, Rapiscan in U.S.A, Nuctech in China, etc. has dominated the CIS market. The prices of CIS equipment are up to 10 millions dollar and also fairly huge amount of maintenance costs are required. Korea customs has fourteen CISs at major ports and borderline in Busan, Incheon, etc. In order to improve the national competitiveness and reduce outflow of foreign currency, Korea Atomic Energy Research Institute (KAERI) has started to develop localized CIS. In this study the relationship between CMS velocity and image optimization was experimentally confirmed. Images are acquired at 70 Hz currently, but optimized parameters which include CMS velocity will be derived through further experiments with different frequency to get the best image qualities in the future.
