Problems solved by technology

However, if the header area 212 is excessively expanded to carry header information in the image indicator 102, the ability of the image indicator 102 to carry indicator data will be reduced instead.
On the other hand, if the micro-image units 216 in the content data area 214 are arranged too densely, or some micro-image units 216 in the content data area 214 are too far away from the header area 212, the image index 102 will also appear in the image. Recognition rate drops in recognition

Embodiment Construction

[0057] Figure 2A It is a schematic diagram of image indicators drawn according to an embodiment of the present invention. Please refer to Figure 2A , in this embodiment, the image indicator 20 includes a linear area 220 and an array area 240 . The linear area 220 includes a plurality of blocks 260A, and each block 260A has a header micro image unit A. As shown in FIG. The array area 240 and the linear area 220 have blocks 260A and 260B to form an index matrix 280 , and the dimension of the index matrix 280 is M×N, where M and N are positive integers greater than 2, respectively. In this embodiment, M is 5 and N is 4, but the present invention is not limited thereto. The array region 240 is composed of a plurality of sub-linear array regions 242 parallel to the linear region 220, each sub-linear array region 242 has a plurality of blocks 260A and 260B, and includes at least one header micro-image unit A and a plurality of The data micro image units B are respectively arra...

Abstract

An image index includes a plurality of first header blocks, a plurality of second header blocks and a plurality of data blocks to form an index matrix. Each first and second header block has a header micro-image unit, and each data block has a data micro-image unit. The second header block and the data block form an array area. The virtual center of the first header block forms a first virtual line, the virtual center of the second header block forms a second virtual line, and the included angle between the first and second virtual lines is less than 90 degrees.

Description

technical field [0001] The present invention relates to an image index that can be read by pattern / image recognition, and the image index corresponds to an index data. Background technique [0002] With the advancement of printing technology and electronic technology, the technology of hiding image indicators in text information or image information visible to the naked eye has been widely used in daily life. Figure 1A It is a schematic diagram of coexistence of image indicators and main information drawn according to known techniques. Such as Figure 1A As shown, a graphical indicator 102 is formed on an object surface 100 . The graphical indicator 102 is composed of many graphical micro-units. Since the micro-graphic units are quite small, they are easily ignored visually or interpreted as background color by human eyes. The image index 102 and main information 104 (such as the character pattern “APPLE” in FIG. 1 ) are jointly formed on the surface 100 of an object such ...
