Embodiment Construction

[0037] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0038] figure 1 It is a flowchart of a data decoding method provided by an embodiment of the present invention. Such as figure 1 As shown, the method of the embodiment of the present invention includes:

[0039] Step 101, acquire a position-coded image sequence.

[0040] Wherein, the position-coding image sequence includes position-coding information and data information. The position-coding information is image information that is position-coded using a position-coding flag. The data information is image information of the input data input by the user.

[0041] Step 102, analyzing the position-coded image sequence, and extracting data information corresponding to each coded symbol.

[0042] Step 103, obtaining the reference position of each coding symbol in the position coding sequence.

[0043] Step 104, compa...

Abstract

The embodiment of the invention relates to a position decoding method and device. The method comprises the following steps of: acquiring a position coding image sequence, wherein the position coding image sequence comprises position coding information and data information; analyzing the position coding image sequence and extracting the data information corresponding to each coding symbol; obtaining the reference position of each coding symbol in the position coding sequence; comparing the data information in the position coding sequence with the corresponding reference positions to obtain position offset information; and decoding the data information in the position coding sequence according to the position offset information.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a position decoding method and device. Background technique [0002] With the rapid development of information technology, people are increasingly using computers to produce, process, exchange and disseminate various forms of information. Information technology is gradually changing people's traditional living habits. The traditional way of writing with paper and pen cannot be processed by information technology, so it cannot meet people's needs. [0003] In the prior art, a coded pattern was used to embed some type of information in a passive substrate such as a sheet of paper, a clipboard or equivalent. For example, human-readable graphical information on the substrate can be supplemented with embedded machine-readable information extending the functionality of the substrate. Such embedded information may include fully or partially reconstructed file d...
