OVERHANG MEASUREMENT METHOD AND APPARATUS FOR BATTERY ELECTRODE PLATE, AND DEVICE AND STORAGE MEDIUM

Provided are an overhang measurement method and apparatus for a battery electrode plate, and a device and a storage medium. The overhang measurement method for a battery electrode plate comprises: acquiring an image of a battery electrode plate; determining the positions of a plurality of electrode plate sides in the image, wherein the plurality of electrode plate sides are electrode plate sides related to an overhang measurement value corresponding to the image, the position of each electrode plate side is determined on the basis of a region where the electrode plate side is located, and the region where the electrode plate side is located is a dynamically determined region; and according to the positions of the plurality of electrode plate sides, determining the overhang measurement value corresponding to the image. The measurement method is used for improving the flexibility and adaptability of overhang measurement.
