Background
Asset labels conventionally use two-dimensional codes, bar codes or numeric/alphabetic codes. The two-dimensional code is a black and white image distributed in a plane two-dimensional direction according to a certain rule, and uses a plurality of geometric shapes corresponding to a binary system to represent literal numerical information by using the concepts of '0' and '1' bit streams based on the internal logic of a computer. The bar code is a graphic identifier in which a plurality of black bars and spaces having different widths are arranged according to a certain encoding rule to express a set of information. Both the two-dimensional code and the bar code can be automatically identified and read by an image input device or an optoelectronic scanning device, but the two-dimensional code and the bar code can hardly be directly identified and read by human eyes.

From the last symbol in the first row, it is a negative code, the adjacent left symbol is a positive code, and the lower symbol is a positive code. If a single code system is adopted, a large number of line segments with the same direction are generated in adjacent symbols in many times, so that the identification difficulty is increased.

The head and the tail of the asset code are respectively provided with a complementary bit character which represents the starting point and the ending point of the whole code and is used for improving the identification accuracy. Each number has two expression modes of a negative code and a positive code, so that the asset codes are generated in a mode of arranging the negative codes and the positive codes at intervals, namely if the first row adopts the negative codes, the second row adopts the positive codes, the third row adopts the negative codes, and the rest is done until the first row is finished; the second row first employs a positive code to ensure a different code scheme than the first row first, the second row second employs a negative code, and so on. Namely, each code is in a code system different from four adjacent codes in the upper, lower, left and right directions. The method can improve the overall uniformity of the graph, improve the recognition rate and reduce the situation of wrong reading.
In this embodiment, when the codes are arranged in an h × h array, the codes are arranged in a sequence from left to right and from top to bottom (modern text typesetting sequence), and may also be arranged in a sequence from top to bottom and from right to left (ancient text typesetting sequence), or in a serpentine or spiral shape (clockwise or counterclockwise, and from inside to outside or from outside to inside), or in other sequences, as required.
