Embodiment Construction

[0066] In order to further illustrate the technical means and effects that the present invention takes to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, its specific implementation, structure, method steps, features and Its effect is described in detail below.

[0067] Please refer to FIG. 1 to FIG. 3 , which are schematic diagrams of high-efficiency information dot matrix graphics of the present invention. The high-efficiency information dot matrix pattern proposed by the present invention is a search area 2 in the center, and then spreads from the center, and the data area 1 is on the periphery, and a dot matrix synchronization area is set between the data area and the search area, or outside the data area 3. On the periphery of the synchronization area, there is a horizontal rotation alignment area 4 as an information dot matrix pattern.

Abstract

The invention relates to a highly efficient information dotting image and its generation and decoding method. It comprises the horizontal rotary aiming, search, synchronic and data areas. It comprises the classification of the original information data, safely processing the information, wrong code correction, pin dot matrix generation and information pin dot image generation. The information pin dot image decoding comprises the abstraction of the information pin dot image information matrix, information matrix correction method and the decoding output. The information pin dot matrix figure uses the innovative center search method being able to quickly and precisely defining the location, angle, and dimension information of the pin dot matrix image. Besides, it can get the dimension right and no deformation information pin dot image.

Description

technical field [0001] The present invention relates to an information dot matrix pattern and its generation and decoding method, in particular to an information dot matrix pattern with high identification efficiency for general-purpose devices with limited functions and its generation and decoding method. Background technique [0002] Information is represented by the arrangement of graphics and identified by identification equipment, which is a major feature of information dot matrix graphics. Information dot matrix graphics are widely used for their advantages of easy identification and low application cost. In recent years, with the continuous popularization of computer applications, the application of information dot matrix graphics has been greatly developed. Information dot matrix graphics can mark the country of production, manufacturer, product name, production date, book classification number, mail start and end location, category, date and other information, so i...
