Automatic Weld Line Inspection

To indicate the quality of the pipe connections, essentially two parameters are critically: The wall offset, i.e. the offset between the left and right pipe, and the K-dimension. Both parameters can be measured using image recording and image processing. During the Innosuisse co-founded research project, it was shown that a backlight image is best suited for this purpose. An X-axis motor is used to move the camera to the optimum position in order to start image acquisition. The image processing software then analyses the images.
