    • Abstract
  • The new welding seam offset identification sy stem of arc sensor was developed with the virtual instrument LabVIEW in this paper.The data detection, wavelet filtering, data normalizing, vertical mean filtering and horizontal dimensionality reduction were depicted based on LabVIEW.The basic principle of the support vector regression machine and data-dependent kernel function was introduced. The algorithm realization of the support vector regression machine withMatlab was proposed.The design method and the control flowchart of the seam offset identification software were proposed using LabVIEW and Matlab.The experiment results confirmed that the way was feasible, the identification precision could meet the actual application in the seam tracking system.
