Automated Acquisition and analysis of digital radigraphic images

摘要

Engineers at the Savannah River Technology Center have designed, built, and installed a fully automated small field-of-view, lens-coupled, digital radiography imaging system. The system is installed in one of the Savannah River Site's production facilities to be used for the evaluation of production components. Custom software ruoutines developped for the system automatically acquire, enhance, and diagnoistically evaluate critical geometric features of various components that have been captured riadiographically. Resolution of the digital radiograms and accuracy of the acquired measurements approaches 0.001". To date, there has been zero deviation in measurement repeatability. The automated image acquisition methodology will be discussed, unique enhancement algorithms will be explained, and the automated routines for measuring the critical component features will be presented. An additional feature discussed is the independent nature of the modular software components, which allows images to be automatically acquired, processed, and evaluated by the computer in the background, whle the operator reviews other imnages onm the monitor.
