A study on the inspection technology of the electrode defects of Li-ion power battery based on HALCON

Li-ion battery becomes an important development direction because of energy shortage and environmental pollution. The electrode is the main part of Li-ion battery, which has the important influence to the performance, cycle life and the capacity of the battery. So, it is necessary that we should accurately detect the surface defects of the electrode. The paper provides a detection approach based on industrial camera and image processing software HALCON. The machine vision technology is used to detect defects of the electrode, and the high-performance software HALCON to process and analyze the acquired image. The combination of software and hardware can improve the efficiency of detection.
