BCH纠错比特:这里我们为了方便,直接查看对应关系,如下图,意思是一个二维码,如果它的纠错等级为H,所采用的的掩码为2,那么后面的二进制字符串即为它所对应的format information。参考地址:https://www.thonky.com/qr-code-tutorial/format-version-tables#list-of-all-format-information-strings ...
校准模块位置表:https://www.thonky.com/qr-code-tutorial/alignment-pattern-locations 例如上方局部图中,版本 2 对应的坐标是 6 和 18,那么校准模块中心点应该位于 (6,6)(6,18)(18,6)和(18,18)位置。但是由于校准模块是在分配完定位模块和隔离模块之后进行分配,所以它不可以覆盖定位模块区域。最终只有不位...
