Claim 15:
16. The method of claim 9, wherein the management platform takes image data at an upstream of the production line in the adjacent second image data as upstream image data, and image data at a downstream of the production line in the adjacent second image data as downstream image data;
the management platform obtains edge data in the upstream image data as upper edge data, and obtains the edge data in the downstream image data as lower edge data; filters out an edge that does not exist in the upper edge data from the lower edge data as a difference edge; and
the management platform selects, from the downstream image data, a pixel whose a pixel value difference with pixel value of the upstream image data is greater than a preset value as a preselected pixel, and filters out, from the preselected pixel, a pixel related to the difference edge to form the first image difference data; wherein the pixel related to the difference edge refers to the pixel located within a closed difference edge or between the difference edge and a graphic boundary.
