Abstract

To guarantee that type E seals are genuine, they are checked to make sure that soldering marks and scratches have not been changed after fitting. This project studied the feasibility of an automatic checking system, using a camera, an analogue-to-digital converter and a computer. Tests were conducted to adjust the different parameters, to assess system performance and to make comparisons with seals in actual use. Reference images were read by the camera, digitised and saved to disk. The digitised images were compared by calculating the correlations coefficient between reference image and actual image.
