Image Processing is slowly making its way into the welding world. With the advent of high dynamic range weld cameras such as the Xiris XVC-1000, images of welding processes can be made with enormous ranges of brightness. As a result, it is now possible to monitor and record good quality video of most welding processes using an HDR camera. With good quality images of the weld pool, arc and seam, the next logical step is to incorporate image processing into the camera system to extract additional information to help operators better control the welding process.
The BlobAnalyzer tool from Xiris is a powerful Blob Analysis tool that can measure a variety of properties of objects within a region of interest. Data can be generated from the properties and then monitored or analyzed so that objects measured or sorted based on their shape parameters. The net result is a new way for fabricators to enhance the monitoring and controlling their weld processes.
The Blob Analysis tool includes properties such as:
Area Centroid Perimeter FormFactor BoundingBox
Orientation Eccentricity EulerNumber Hole Count TouchesBorder
FeretDiameter GrayMass GrayMean Compactness
Conclusion
By incorporating image processing tools such as Blob Analysis into their weld camera systems, machine builders can measure features of their weld processes in a way that has never before been possible. It is now possible to find features in an image, such as the weld arc, or seam, that could allow for further monitoring or analysis, or form the foundation for seam tracking or weld pool geometry analysis.
