Lithium battery tab number detection method and system

The invention discloses a lithium battery tab number detection method and system, and relates to the technical field of lithium battery detection, and the method comprises the steps: collecting a lithium battery tab picture on a production site, and carrying out the preprocessing; performing feature enhancement on the preprocessed tab picture, finding out an optimal scribing position, and making a data set; and training the detection identification model, sending a to-be-detected tab picture to the trained model for detection, determining the number of tabs, and determining the qualified state of the battery according to the number of tabs. Through the combination of the learning model and image processing, errors caused by man-made misjudgment and precision limitation of mechanical equipment can be effectively avoided, automatic image processing and deep learning are utilized, tab number detection of a large number of pictures can be rapidly completed, the production efficiency is remarkably improved, traini
