Automatic Industrial CT Image Processing and Analysis of Batch Workpiece NDT Based on the VGStudio SDK

The Industrial Computed Tomography (ICT) is an advanced NDT technology to get exact internal and external structure information of the tested specimen. The nondestructive testing personnel can control the outgoing quality of workpieces by ICT image processing and data measurement. In this paper, we introduce high energy industrial CT system with accelerator X-ray source which is developed for batch NDT of production process. In this ICT system, multiple workpieces CT scanning can be carried out at the same time, and the CT images of different positions can be acquired to the image inspection workstation. Obviously, the testing personnel are very difficult to meet the requirements of batch NDT manually. In this study, the template matching algorithm was adopted to split this kind of CT image into single specimen and store in different images. This paper introduces the development of image auto-analysis based on the SDK of the VGStudio Max. The results show that individual specimen is more accurate and the effect of automatic analysis is satisfactory. In Summary, we propose the auto-processing method for the batch NDT and for high efficiency in application.
