Weld seam tracking is the key technology of industrial robot. It satisfies accuracy and real-time demand. This paper presents a robust recognition algorithm for weld seam images based on mathematical morphology. This algorithm used the morphological filtering for image enhancement at first, and then applied Otsu threshold segmentation in local. Besides, it implemented region filling and morphological thinning operation to get the segmented weld seam. Finally, the Hough transform was adopted to detect the straight lines from the weld image. The results prove that this method not only can detect the seam tracking in real-time, but also can identify weld seam automatically.

In the process of weld seam tracking, traditional mathematical model of classical and modern control theory is hard to meet the requirement of high performance controller. This article based on the embedded digital signal processor DSP-TMS320F2812 for the field of industrial automation control.The fuzzy control technology is applied to real-time welding seam-tracking system, according to the F2812 which has the characteristics of real-time multitasking scheduling of resources and then designed the real-time control value adjustment Fuzzy-PI control system. The designed DSP real-time fuzzy control system gives full play to powerful control and signal processing ability of F2812, it can fully adapt for the controlling requirement of super-speed and high-precision.
