The scope of this project is to develop an image processing system for a pipe welding robot. The robot control system will rely on feedback from the image processing algorithms to determine the location of the welding electrode in relation to the weld seam edges to correct positional errors. It is anticipated that to achieve these objectives the following general steps will be required: 1) Establish a coordinate system 2) Calibrate the image 3) Window the image (for weld pool and weld seam edges) 4) Remove interlacing artefacts 5) Apply a median filter 6) Apply a sharpening filter 7) Identify edges using a modified Canny operator 8) Remove false edges 9) Scan for edges 10) Fit functions to the edges 11) Determine the positional error 12) Interface to the control system Refer attached illustrations for further information.
