Algorithm and Three-Dimensional Reconstruction for Tungsten Inert Gas Arc Welding Pool Surface

Abstract

Abstract:

Abstract： To measure the highly dynamic and irregular mirror surface of the welding pool, the mathematical model for reconstructing the TIG welding threedimensional surface was proposed based on the existing algorithm. To reconstruct the threedimensional surface of different convex and concave using the new algorithm, lasers were reflected by different three-dimensional surface reforming different lasers dots matrix distribution on the imaging screen. The Matlab software was used to compile the corresponding procedures for the visualization of the welding pool. The result shows that mathematical model can better reflect the level of the welding pool surface successfully by relying on the lasers dots matrix distribution on the imaging screen, but in order to improve the reconstruction accuracy, more constraints should be applied.
