[0065] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0066] First, let’s explain the terms involved in this application:

[0067] Edge straightness: refers to the straightness of the edge of the tile. Usually a ruler or special measuring tool is used to place the ruler close to the edge of the tile, and the maximum gap between the ruler and the edge is checked and measured. This gap value represents the deviation of the edge straightness.

[0068] Related technologies calculate the straightness of a tile's edge by measuring the vertical distance between each point on the tile's edge and a reference position in a tile image. This straightness refers to the degree of straightness of the tile's edge. This is typically done with a ruler or specialized measuring tool. The ruler is placed against the tile's edge, and the maximum gap between the ruler and the edge is measured. This gap represents the deviation in straightness. However, this method is time-consuming.

[0069] Therefore, how to achieve faster tile quality detection by quickly calculating edge straightness is a technical problem that needs to be solved urgently by those skilled in the art.
