Embodiment

[0070] Combine below figure 1 Describe in detail the process of an implementation method of an office affairs process management system:

[0071] The system is composed of information reading part, information embedding part and printing output part.

[0072] The information reading part reads the information to be embedded from the memory, the external device, and at least one device in the network, and converts it into computer code; After each group of data is transformed from 8 bits to 9 bits, the continuous "1"s that appear in the encoding are broken up, so as to avoid the occurrence of horizontal continuous black spots during the embedding process and affect the quality of the embedded image, and at the same time facilitate the embedding Identify the embedded information; embed data in the form of a dot matrix in the rectangular embedding area, that is, in a two-dimensional dot matrix arranged at regular equidistant intervals, each dot corresponds to an information bit....

Abstract

The invention provides a method for identifying a screen code with uniform dot matrix. The method for identifying the screen code includes the following steps: the printed image of the screen code which is read and printed on a paper document is processed by the operations of 9-bit to 8-bit conversion and RS decoding treatment; the method for identifying the screen code aims at solving the problem that the appearance of transverse and continuous black spots influence the angle-free identification of the screen code serving the quality of an embedded image, and the method has the characteristics of high identification speed and recognition rate, can be applied to the entering and the trace treatment of serial numbers of various document information commonly used in routine work, the content of the information, the state of play of business handling, the results of treatment, and the like, can reduce the repetitive entering, can improve the working efficiency, and can supervise the treatment of the documents at any time.

Description

technical field [0001] The invention belongs to information processing technology, in particular to a method for identifying screen codes with uniform dot matrix. Background technique [0002] In recent years, computer technology has developed rapidly. As a medium for recording data information, it has developed from the initial magnetic medium to optical medium and memory medium. But plain paper as a medium for storing large amounts of data is rarely mentioned. [0003] In addition, as a simple method of supermarket settlement at first, a one-dimensional bar code was proposed by Harvard University in the United States in 1932, and it has been widely used until now. In the late 1980s, in order to meet the needs of industries such as gemstones, semiconductors, pharmaceuticals, and mechanical products to record more information, Code49 was developed by Intermec in 1989, and the two-dimensional barcode was born. Since then, DataMatrix, MaxiCode, ArrayTag, etc. have appeared o...
