A graphical indicator comprising a plurality of first header blocks, a plurality of second header blocks and a plurality of data blocks for forming an indicator matrix is provided. Each of the first and second header blocks has a header graphical micro-unit, and each of the data blocks has a data graphical micro-unit. An array area is formed by the second header blocks and the data blocks. A first virtual line and a second virtual line are respectively formed by virtual centers of the first and second header blocks, and an included angle between the first and second virtual lines is less than 90 degrees.

Graphical indicator

A method for reading a graphical indicator is provided. The method includes the following steps. An indicator image including a plurality of graphical micro-units is obtained. According to a portion of the graphical micro-units, a first header part and a first content data part belonging to a first image indicator are obtained. According to another portion of the graphical micro-units, a second header part and a second content data part belonging to a second image indicator are obtained. The graphical micro-units of the first content data part are further used to obtain the indicator data. When a portion of the graphical micro-units in the first content data part is lost, the complete graphical micro-units can be obtained by recovering the lost graphical micro-units of the first content data part according to the graphical micro-units belonging to the first and the second content data parts captured in the indicator image.
