摘要
In the weld seam-tracking system based on machine vision, the welding seam images acquired in the welding process are mixed with strong noises because of the effect of welding conditions. This makes it difficult to get precise seam situation. In this paper, a new edge extraction algorithm based on the fractal theory was introduced to seek welding edge';s position in the seam images with noises. In this algorithm, seam images are analyzed depending on the fractional Brownian field model, and the fractal dimen...
