Battery detection method and device, computer equipment and storage medium

The invention relates to a battery detection method and device, computer equipment and a storage medium. The method comprises the following steps: detecting a battery image of a top cover welding process by using a pre-trained welding spot detection model to obtain a welding spot detection result; performing gray processing on the battery image to obtain a gray image; determining a welding spot area and a welding seam area according to the welding spot detection result and the grayscale image; detecting the welding spot area and the welding seam area to obtain a battery detection result; the battery detection result is used for representing that a welding spot of the battery is abnormal or normal and a welding seam is abnormal or normal. The battery can be automatically detected, the cost is low, the efficiency is high, and the quality of the battery can be improved.
