Abstract

In recent years, machine vision sensors have been widely used to track weld seam. A suitable way is designed to process image of aluminum alloy pulsed gas tungsten arc welding process experiments in this work. With the passive vision sensor to capture some ideal images, we adopt and compare different image processing methods to extract useful information, including target location, double filter, edge detection and seam centerline extraction. It is shown that the method has good effect on seam centerline extraction and seam tracking.
