The first area 110 may correspond to a boundary of a mold or a boundary of a test piece, or the first area 110 corresponds to a boundary of a mold and a boundary of a test piece, for example, the first frame and the second frame respectively correspond to a boundary of a mold and a boundary of a test piece, so as to provide a positioning reference for a user, and facilitate accurate image acquisition. The second area 111 is a position to be implanted or attached of the first anti-counterfeit label 210, and in order to improve the anti-counterfeit effect, the first indication mark 121 is dynamically formed in the first area 110, wherein the dynamic formation can be understood as that the first indication mark 121 appears at different positions in the first area 110 according to a preset rule, so that the position to be implanted or attached of the first anti-counterfeit label 210 cannot be artificially predicted, and the anti-exchange effect is further achieved.
S120, according to the first indication mark 121, a first anti-counterfeiting label 210 is implanted or stuck to the first surface of the first test piece, and a plurality of first positioning reference points 211 are arranged on the first anti-counterfeiting label 210.
Referring to fig. 2, in the embodiment, the first indication mark 121 is a rectangular frame, and certainly, the first indication mark 121 may also be other marks adapted to the first anti-counterfeit label 210, such as a circular frame, a positioning point, or a mark line. After the first test piece is manufactured and in an unset state, the first anti-counterfeit label 210 is implanted or stuck in the second area 111 according to the first indication mark 121, the first anti-counterfeit label 210 carries anti-counterfeit information, the anti-counterfeit information can be loaded in an RFID chip inside the first anti-counterfeit label 210, the anti-counterfeit information can be associated with a two-dimensional code or a bar code on the surface of the first anti-counterfeit label 210, the first positioning reference point 211 can be a black or colored mark point, and the mark point can be triangular, circular or prismatic. The first anti-counterfeit label 210 of this embodiment is provided with the two-dimensional code, and the corner position of two-dimensional code is provided with three setpoint 201, and the outside of two-dimensional code is provided with annular graduator 202, and it has 8 first location reference points 211 to distribute on the graduator.

The angle information is angle data of the first positioning reference point 211 in polar coordinates, for example, the angle information may be an angle of a connection line between the first positioning reference point 211 and a coordinate reference origin with respect to a horizontal boundary or a vertical boundary of the first image, or the angle information may be angle data between any two first positioning reference points 211 and the coordinate reference origin. In order to improve the accuracy of the subsequent anti-counterfeiting comparison, the number of the first positioning reference points 211 is 8, and each first positioning reference point 211 can be distinguished through the sequencing information.
