Abstract:
(EN) The invention discloses methods of encoding and reading a 2D bitmap barcode comprising MxN virtual dot storage blocks. The method comprises: forming, by filling dots into the virtual dot storage blocks, a plurality of coordinate calibration blocks, a plurality of data storage blocks, and a direction indication block; wherein each of the plurality of coordinate calibration blocks is filled with only one dot located at the center location of the virtual dot storage block; the direction indication block is filled with two or more dots, and one dot thereof is located at the center location of the virtual dot storage block; the plurality of coordinate calibration blocks and the direction indication block are separated from each other and distributed in the plurality of barcode storage blocks; the dots filled in the plurality of barcode storage blocks are used to store data information; and M≥4, N≥4, M and N are both even numbers. The invention has advantages of having a large encoding capacity and small interference to human vision, and being simple and reliable to identify.
(FR) L'invention concerne des procédés de codage et de lecture d'un code à barres 2D à table de bits comportant M x N blocs de mémorisation de points virtuels. Le procédé comprend la formation, grâce au placement de points dans les blocs de mémorisation de points virtuels, d'une pluralité de blocs d'étalonnage de coordonnées, d'une pluralité de blocs de mémorisation de données et d'un bloc d'indication de direction, chaque bloc de la pluralité de blocs d'étalonnage de coordonnées ne contenant qu'un point situé à l'emplacement central du bloc de mémorisation de points virtuels, le bloc d'indication de direction contenant au moins deux points, l'un de ces points se trouvant à l'emplacement central du bloc de mémorisation de points virtuels, la pluralité de blocs d'étalonnage de coordonnées et le bloc d'indication de direction étant séparés les uns des autres et répartis dans la pluralité de blocs de mémorisation de code à barres, les points contenus dans la pluralité de blocs de mémorisation de code à barres servant à mémoriser des informations de données, M ≥ 4, N ≥ 4, et M et N étant tous deux des nombres pairs. L'invention a pour avantages de présenter une grande capacité de codage, de ne perturber que peu la vision humaine, et d'être simple et fiable à identifier.
(ZH) 本发明公开了一种点阵二维码的编码和识读方法,所述点阵二维码由M×N个虚拟码点存储区块组成,通过在虚拟码点存储区块内填充码点分别形成多个坐标校正区块、多个数据存储区块和一个方向指示区块;多个坐标校正区块内所填充的码点有且仅有一个并均位于虚拟码点存储区块的中心位置;方向指示区块内填充有至少两个码点,其中仅有一个码点位于虚拟码点存储区块的中心位置;多个坐标校正区块和方向指示区块均相互隔开,分布于多个数据存储区块之间;多个数据存储区块内填充的码点用于存储数据信息;其中,M≥4,N≥4,M与N均取偶数。本发明具有编码容量大、对人眼的视觉干扰小、可被简单可靠识别等优点。
