Claim 3:
4. The method of claim 2, wherein determining whether the code identifier in the image of the detection region is the chip code image based on the signal strength difference between the signal strength of the code identifier in relationship map and the signal strength of the code identifier at the preset position comprises:
setting that di=1 when ai is greater than aj, and di=0 when ai is not greater than aj, wherein i is configured to represent a sequential position index value, j is configured to represent a current position index value, an is configured to represent signal strength of a code identifier position n, and dn is configured to represent a determination value of the code identifier position n;
A1: in an initial state, setting that i=1 and j=1, and obtaining a value of d1 based on a0 and a1,
A2: incrementing i by 1, and obtaining a value of di,
A3: determining whether the values of di and d1 are equal, and performing A4 when di=d1, and performing A5 when di≠d1,
A4: setting that j=i, and performing A2,
A5: determining whether |i−j| is greater than t, performing A6 when |i−j|>t, and performing A2 when |i−j|≤t, wherein t is configured to represent a tolerance value,
A6: setting that j=i, s is incremented by 1, and di=1−di, performing A2,
A7: performing A2 when s<b, and determining that the image of the detection region comprises the chip code image when s≥b, wherein b is configured to represent a required number of standard amplitudes, and s is configured to represent a counted number of amplitudes in current position.
