Abstract: A terminal can include a display and a processor configured to generate a reconstructed image based on a plurality of X-ray images of a battery, and rotate the reconstructed image by a predetermined angle to generate a tilting image. Also, the processor can generate an electrode detection image based on the tilting image, the electrode detection image including a positive electrode of the battery and a negative electrode of the battery in which the positive electrode and the negative electrode are separated from each other, and detect whether the battery is defective based on the electrode detection image.
