| Abstract: | A new real-time weld seam image extraction and processing method based on CCD sensor was introduced.It is specially designed for the 2 mm-deep aluminum alloy sheets welding without an obvious weld seam between two sheets.Considering the characters of aluminum alloy welding,it developed an adequate dimmer-filter glass system,and gained a clear real-time weld seam image.Then a series of image processing algorithm routine was used to get weld seam in the image,which demonstrates a feasible and effective result. |
