| Summary: | A digital examination device for non destructive testing (NDT) such as digital radiography is nowadays increasingly applied in fabrication or welding industry to inspect defects in materials. The digital image can be acquired with high time efficient and less radiation compared to film based technology. Due to the system complexity, parameter sensitivity and environmental effect, noises can however easily occur in the digital image which can indicate low quality image and result in difficulty for interpretation. Therefore, a need of an application tool which can improve and evaluate the image is becoming an urgent task. Due m this fact, a novel interactive, comprehensive and user-friendly tool was developed which enable the digital image improve, analyze and automatically transfer to reporting. This tool was written by using image processing and guide toolbox in MATLAB which contains four main sections, namely: (1) Theoretical Background as Knowledge Pool, (2) Image Processing Method, (3) Image Quality Measurement Method and (4) Radiographic Inspection Report (RIR). This tool is potential to be used in manufacturing industry such as welding fabrication and casting process. High quality manufactured products can be achieved through appropriate inspection and record. Hence, defects can be traced easily through a proper database which encourages the industry sustaining high quality of products. |
