OPTIMISATION OF THE RADIOGRAPHICAL TEST METHODS FOR THE AUTOMATIC ASSESSMENT OF REAL-TIME PHOTOGRAPHS IN THE STEEL INDUSTRY
The nondestructive testing of steel products uses little or no radiography, except for weld inspection. Nevertheless, powerful electronic devices are now available, instead of photographic films, which allow fast image acquisition and digital image processing. In a joint research project BAM, BFI, INSA and IRSID have evaluated and developed the field of applications and the methods of real-time X-ray inspection. Concerning the BFI/BAM-part, by connecting digital image processing systems with real-time imaging systems, an increase in image quality and objective and reproducible location and classification of defects could be attained. The main subjects in the German work were measurements and developments for two dimensional imaging systems and the description and development of software for automatic image interpretation. In addition some work was done to make a comparison of X-ray film and real-time techniques by using existing imaging and image processing systems. The results of the project could be used for the definition of an industrial testing system.
