Data output/input method with application of image index structure

Abstract

The invention provides a data output / input method with application of an image index structure. The data output / input method comprises the steps of: forming at least one image index structure corresponding an index datum on an object surface, wherein the image index structure comprises a content data part and a header part, the content data part comprises a plurality of micro image units, a region occupied by the content data part is divided into a plurality of state regions, each state region is provided with one micro image unit, the micro image unit is optionally located in one of a plurality of virtual regions formed by uniformly dividing the state region, the header part comprises a plurality of micro image units which are arrayed in a preset manner so as to provide header information for recognizing an image index; and optically reading the object surface so as to obtain an amplified image containing the image index structure to further capture the index data corresponding to the image index structure.

Description

[0001] This application is a divisional application of the patent application entitled "Image Index Structure" with the application number "200610075770.8" filed on April 26, 2006. technical field [0002] The invention relates to an image recognition (pattern / image recognition) technology, in particular to a data output and input method using an image index structure. Background technique [0003] figure 1 A schematic diagram of a graphical indicator 102 formed on an object surface 100 is shown. like figure 1 As shown, the image indicator 102 is composed of a number of micro-image cells combined. Because the micro-image units are quite small, they are easily overlooked visually, or interpreted by the human eye as undertones. Image indicators 102 and main information 104 (eg figure 1 The character pattern "APPLE") is jointly formed on the surface 100 of an object such as paper by means of printing, for example. The image indicator 102 corresponds to an indicator data, a...

Problems solved by technology

[0006] like figure 1 As shown, the image index 102 usually coexists with the main information 104 on the object surface 100; therefore, when the density of the micro-image unit is higher, the visual effect is worse, and the human eye is more likely to perceive the existence of the image index 102 and make the image index 102 Increased chance of confusion with main message 104

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
