Abstract
The invention belongs to the field of welding seam three-dimensional reconstruction, and discloses a welding seam structure modeling method and system and a welding device. The method comprises the steps of obtaining a weld seam image through a small line scanning technology; processing the weld seam image by adopting adaptive median filtering to obtain a de-noised weld seam image; processing the de-noised weld seam image through an improved gray centroid method to obtain a sub-pixel-level light stripe center line; through a curvature analysis technology, carrying out feature point identification on the center line of the sub-pixel-level light stripe, and superposing marked feature points on the de-noised weld seam image to obtain a feature weld seam image; based on the feature welding seam image, converting the sub-pixel-level light stripe center line into a three-dimensional point cloud, and generating a welding seam curved surface model; dynamically adjusting the welding current based on the weld joint curved surface model; and the welding effect is effectively improved.
