Method of operating a radiographic inspection system with a modular conveyor chain

摘要

The method of operating a radiographic inspection system is specifically designed for a radiographic inspection system in which a conveyor chain with identical modular chain segments is transporting the articles under inspection. The method encompasses two operating modes of the radiographic inspection system, i.e. a calibration mode in which calibration data characterizing the radiographic inspection system with the empty conveyor chain are generated and stored as a template image, and an inspection mode in which raw images (50) of the articles (3) under inspection with the background (41) of the conveyor chain are acquired and arithmetically merged with the template image. As a result of the process, a clear output image (51) of the articles under inspection is obtained without the interfering background of the conveyor chain.
