Antireflective Weld Seam Trajectory Recognition and Localization Method Based on Polarization–Laser Vision

Highly reflective metallic materials such as aluminum alloys significantly degrade the performance of laser vision-based weld seam identification due to strong specular reflections. To achieve fast and robust weld seam trajectory recognition and localization under such conditions, this paper proposes an active laser vision system with a polarization-parameter-based reflective noise suppression method. Exploiting the polarization characteristics of reflection, a masking strategy is proposed to su
