英文摘要	A new method was proposed to measure 3D outline of groove and weld surface by laser vision. When the laser stripe was scanning continuously on the surface of groove and weld, the image of stripe could reflect the outline feature and be taken as information source. The measurement system acquired a series of laser stripe images and all the discrete points of 3D coordinates. At the same time, 3D discrete coordinates between laser stripes were obtained through an interpolation algorithm of searching and fitting. Then a surface reconstruction method where discrete points were linked to grids was used to obtain the 3D outline of groove and weld. The validation results showed the matching degree of groove width and depth from three-dimensional surface outline was up to 97.85% in each section, which proved that this laser vision measurement was feasible. © 2017, Editorial Board of Transactions of the China Welding Institution, Magazine Agency Welding.
