摘要：

To understand, analyze, and control the metal transfer process of double-electrode gas metal arc welding (DE-GMAW), the droplet should be monitored in real time. Due to the fast development and transfer of the droplet, the monitoring speed becomes the key. A tracking method that takes advantage of results from previous images to speed the processing is advantageous. In this paper, Kalman Filter tracking and Least Square Match tracking algorithms are studied. Finally, a real time template updating and LSM tracking method is proposed to track the droplet effectively. Experimental results verified its tracking accuracy.
