Image indexing structure

Abstract

The invention provides a data input / output method by means of an image index structure, which comprises the steps of forming an image index structure of index data at least in an one-to-one relationship on the surface of an object; and optically reading the surface of the object to obtain the magnified image of the image index structure for retrieving index data corresponding to the image index structure. The image index structure comprises a content data part and a header part. The content data part consists of a plurality of micro image units and the area of the content data part is divided into a plurality of status regions. Each status region is provided with a micro image unit and the micro image unit is selectively located in one of a plurality of virtual regions, wherein the plurality of virtual regions are formed through the uniform division of the status region. The header part consists of a plurality of micro image units and the plurality of micro image units are aligned in a predetermined arrangement so as to provide the header information for the identification of the image index.

Description

Technical field [0001] The present invention relates to an image recognition (pattern / image recognition) technology, specifically, a data output and input method using an image index structure. Background technique [0002] figure 1 It is a schematic diagram of a graphical indicator 102 formed on a surface 100 of an object. Such as figure 1 As shown, the image index 102 is composed of many micro image units. Because the micro image unit is quite small, it is easy to be ignored visually or interpreted as a background color by the human eye. Image indicator 102 and main information 104 (such as figure 1 The text pattern "APPLE") is jointly formed on the surface 100 of an object such as paper using methods such as printing. The image index 102 corresponds to an index data, and does not affect the reception of the main information 104 by the human eye. [0003] figure 2 It is a schematic diagram of an electronic system 110. The electronic system 110 has an optical device 112, a pro...

Problems solved by technology

On the other hand, when the image index 102 is formed in a limited object surface area, under the premise of providing the same amount of information, the excessively high distribution density of micro-image units will cause the distance between two adjacent micro-image units to be too small; therefore , when the micro-image units are formed on the paper by, for example, printing, it will cause more obvious visual disturbance

If this visual interference is to be reduced, it is usually necessary to further reduce the size of the micro-image unit, which will increase the resolution requirements of the printing press and paper, and it is also easy to miss dots during printing, which relatively increases the difficulty of printing and is likely to cause damage to the optical device. Misinterpreted or difficult to distinguish

image 3 The design of the existing image index 102 shown clearly leads to an excessively high density of micro-image units, thereby causing the above-mentioned various problems
