The present invention provides a method, device, system, and storage medium for determining a position code of a multi-ary coded pattern. The position code encodes the first dimension and the second dimension of the multi-ary coded pattern. The method includes: a reading device acquires multiple The coding of the first predetermined number of code points in the binary system coding pattern, the coding of the code points includes the first dimension coding and the second dimension coding; the coding of the first predetermined number of code points is input into the coding device, and the coding device is based on the first / two-dimensional The encoding determines the position code of the code point on the first / two-dimensional dimension; wherein, the first dimension includes the position offset of the code point, and the second dimension includes the size of the code point. According to the method, device, system and computer storage medium of the present invention, the determination of the position code of the multi-ary encoding pattern is realized through the two dimensions based on the position offset of the code point and the size of the code point, which significantly reduces the processing capacity of decoding and reduces the Power consumption, increase processing speed, increase frame rate, and further improve the smoothness of the decoding trajectory.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, system and storage medium for determining a position code of a multi-ary coded pattern. Background technique [0002] With the wide application of two-dimensional coordinate patterns, the coding requirements for two-dimensional coordinate patterns are getting higher and higher. At present, there are generally two coding schemes for determining two-dimensional coordinate patterns: one is similar to a QR two-dimensional code, and a square coding pattern is used as a position unit. For example, the pattern lattice of a 4*4 square lattice can have a maximum of 65536 types The change of , means that 65536 positions can be determined. This scheme is a common scheme for point-reading pens. The advantage is that the encoding and decoding is simple, but the disadvantage is that there is too little position information; The advantage of this scheme is that t...
