摘要： A method of generating binary positioning tags includes the following steps: generating a pseudo random sequence; circularly shifting the pseudo random sequence and sequentially filling in one of a plurality of odd rows and a plurality of even rows of a binary matrix, wherein a size of the binary matrix is M×N; filling a complement sequence of the pseudo random sequence in the other one of the plurality of odd rows and the plurality of even rows; and retrieving a binary submatrix having a size of I×J from the binary matrix according to a relative position of a positioning point to be used as a positioning tag corresponding to the positioning point, wherein I is smaller than M, and J is smaller than N. Accordingly, it is possible to provide a positioning tag that is highly secure, arrangement-unique, and easy to obtain and analyze.
