To realize fully automatic rust removal from the large splicing weld of a ship hull section, we
proposed a laser vision identification method based on three-line laser structural light. First …

The real-time tracking of a weld line for the removal of rust can significantly improve the
derusting efficiency and autonomy of a wall-climbing robot, wherein, weld line detection and …

The" teaching-reproduction" mode and off-line programming mode are widely used in
traditional welding robots. For curved welding workpieces, the operators need to visually …

During the welding manufacturing of a circular pressure vessel, the V-type seam's position
relative to welding torch varies dramatically due to the seam curvature change or axial …

In this study, we propose a precise 3D lug pose detection sensor for automatic robot welding
of a lug to a huge steel plate used in shipbuilding, where the lug is a handle to carry the …

With the ongoing progress of industrial technology such as shipbuilding, the importance of
weld quality in industrial production is becoming increasingly prominent. Intelligent and …

Purpose This paper aims to propose a set of six-axis robot arm welding seam tracking
experiment platform based on Halcon machine vision library to resolve the curve seam …

A real-time robotic weld tracking system based on laser vision sensor is designed for
intersecting seam. Firstly, the traditional image processing method is used to determine the …

Full autonomy is the ultimate goal in robotic welding. Heretofore, to weld a fillet weld seam
formed by two steel plates, the initial weld position had to be found by procedures that …

In this study, a laser-based machine vision system is developed and implemented to monitor
and control welding processes. The system consists of three main modules: a laser-based …
