Abstract: A detection method includes acquiring a first shot image of a long-side weld of a battery cell under detection by using a first structured light camera on a long side of the battery cell under detection, acquiring a second shot image of a short-side weld of the battery cell under detection by using a second structured light camera on the short side of the battery cell under detection, detecting a defect of the long-side weld of the battery cell under detection based on the first shot image, and detecting a defect of the short-side weld of the battery cell under detection based on the second shot image.
