[Abstract]:In this paper, the imaging system based on Dr is designed and realized by using the XRD0822 flat panel Dr detector produced by PerkinElmer Company, combined with the field hardware testing equipment and the steel pipe production process. The system designed and implemented has been tested by field operation, and the test results show that the system can fully meet the production requirements of the factory. This system adopts document / view architecture technology to develop, therefore, this paper first introduces some key programming techniques used in this development, then, discusses the composition of the system, including Dr detector principle, hardware system structure, Finally, the programming technology of system design and implementation is discussed in detail. The design and implementation of the system is the core of this paper. The detailed design of the system is given, and the methods of converting 16-bit image to 8-bit image, image compensation and weld seam boundary detection are studied. In the realization part of the system, according to the interface and function of the software design, combined with the MFC programming technology and the acquisition principle of Dr flat panel detector, the collection of image number, real-time display, recording and replaying of data, detection of the boundary of weld seam are realized. Image conversion with enhanced code writing. The developed system is currently in the process of trial operation.
