The welding quality of power battery sealing nails directly impacts battery safety and service life. Traditional 2D inspection struggles to detect 3D defects such as weld height, blowholes, and porosity, while manual inspection suffers from low efficiency and high false negative rates that can't keep pace with mass production. OdinVision delivers a combined 2D+3D vision solution to achieve full-dimensional automated inspection of sealing nail welding defects.
