Disclosed in the present application are an electrode sheet inspection method and system. The method comprises: acquiring an image to be subjected to inspection, which is collected from an electrode sheet; on the basis of preset edge-capture region information, determining at least one edge-capture region from the image, wherein the preset edge-capture region information comprises position information and/or size information of the edge-capture region; performing boundary detection on each edge-capture region, so as to obtain a first boundary line in each edge-capture region, wherein the first boundary line is used for delineating different partitions of the electrode sheet that are arranged in a widthwise direction; and using the first boundary line in each edge-capture region to determine width information related to the electrode sheet. In this way, the present application can implement automatic inspection for an electrode sheet.
