Three Dimension Curve Welding Seam Modeling for Seam Tracking
A novel modeling method for 3D curve welding seam is presented in this paper based on a welding robot for large workpiece. The 3D curve welding seam tracking is implemented by macro and micro motion which can control translational motion of torch in a large range and implement accurate seam tracking in small range. As such, the self-teaching seam model and real-time seam model are established t...
متن کاملRobotic Seam Tracking
The principles of contact and non-contact sensors for robotic seam tracking arc revicwcd. Non-contacting scnsors arc bascd on either an clectromagnctic or an acoustic principle. Electroinagnctic sensors in thc low frcqucncy rcgime induce eddy currents which can bc uscd for the dctcction of surface discontinuitics. In the high frequency regimc (visual spectrum), laser light stripe systems in con...
متن کاملGeometry seam carving
We present a novel approach to feature-aware mesh deformation. Previous mesh editing methods are based on an elastic deformation model and thus tend to uniformly distribute the distortion in a least squares sense over the entire deformation region. Recent results from image resizing, however, show that discrete local modifications like deleting or adding connected seams of image pixels in regio...
متن کاملRobotic seam tracking
The principles of contact and non-contact sensors for robotic seam tracking are reviewed. Non-contacting sensors are based on either an electromagnetic or an acoustic principle. Electromagnetic sensors in the lovi frequency regime induce eddy currents which can be used for the detection of surface discontinuities. In th( high frequency regime (visual spectrum), laser light stripe systems in con...
متن کاملSeam-Driven Image Stitching
Image stitching computes geometric transforms to align images based on the best fit of feature correspondences between overlapping images. Seam-cutting is used afterwards to to hide misalignment artifacts. Interestingly it is often the seam-cutting step that is the most crucial for obtaining a perceptually seamless result. This motivates us to propose a seam-driven image stitching strategy wher...
