Research and Application of Digital Image Processing Technology in Cobalt-60 Based Container Inspection System

摘要

Container inspection system is characterized as greatly changing dynamic range, geometric distortion, counting fluctuation and interference data, etc. This paper introduces an approach to generate two-view images for comparison by means of image data acquisition, a method to reconstruct 3D reviewing, and processing technology with a special image correction algorithm, that is to correct image data acquired first and then adjust image gray datum line and contrast combining with other image processing methods, which greatly improves image quality of Cobalt-60 based inspection system compared with ordinary image processing methods.
