矩阵的左上、左下、右上分别有 1 个 7x7 的定位图案 FINDER PATTERN,用于 QR Code 的查找定位,在其周围会环绕宽度为 1 像素的分隔符 SEPARATOR,用于分割功能图案和编码区。还有两段水平和垂直的黑白相间的区域,为 TIMING PATTERN,用于确定 QR Code 的像素密度和模块的基准位置。在编码区中,深灰色的像素块用于...
Color is a powerful part of your brand—and your QR code should reflect that. With QR Code KIT’s QR code generator, you can fully customize your code’s color scheme to match your branding or a specific campaign theme. You can apply solid hues or gradients to the pattern, the backgrou...
When you scan a QR Code, the camera focuses on the smaller square at the bottom right of your QR Code pattern. This square helps as a backup position pattern to orient the image. The bigger a QR Code gets, the more alignment patterns it needs for scanning. The alignment pattern is espe...
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...

ECL是H,那就没错了,剩下的参数里面,这个QR_MASK_PATTERN不就是掩码参数咯,剩下两个看了下参数介绍,应该不是很重要,于是重点关注QR_MASK_PATTERN。刚好手头的代码引用的是ZXing,这里要注意的是,ZXing的Hints是不能整个赋值的,只能用Add的方式逐个插入参数 果然,结果跟原图一样(外面的圈是我自己加的):问题已经...
At first glance, a QR code looks like a random patchwork of black and white squares. But there’s method in the mosaic. Every square—every pixel—is part of a carefully crafted pattern that tells a digital story. Here’s how it works: each black square is a binary “on,” and each...

QRCode 主要由以下部分组成: 1 - Position Detection Pattern:位于三个角落,可以快速检测二维码位置。 2 - Separators:一个单位宽的分割线,提高二维码位置检测的效率。 3 - Timing Pattern:黑白相间,用于修正坐标系。 4 - Alignment Patterns:提高二维码在失真情况下的识别率。
