读取二维码时的错误修正
我正在与客户合作，通过二维码推广他们的网站。他们想在杂货店的地板贴花上贴上二维码。
我担心它的表现如何，因为随着时间的推移，地板贴花会因行走、溢出等而磨损。
考虑因素之一是它的印刷方式（材料和墨水）以及二维码本身的大小。但是解码算法如何纠错呢？这还是一个需要考虑的问题吗？
I am working with a client to promote their site via QR Codes. They would like to put a QR code on floor decal in a grocery store.
I am concerned about how well this will perform as the floor decal is worn down over time via walking, spills, etc.
One of the considerations would be how its printed (material and ink) and the size of the QR code itself. But how do the decoding algorithms error correct? Is this even an issue that needs to be considered?

它是 Reed-Solomon 编码的实现，因此相当健壮。可以配置用于生成 QR 码的应用程序，请参阅此处的博客文章：

It is an implementation of Reed-Solomon coding, so it's fairly robust. The application used to generate a QR code for you can be configured, see a blog post here:

我是错误帖子的作者更正。
为了获得最佳结果，您需要将错误纠正设置为“H”，即“高”。
这将导致多达 30% 的代码被损坏。
注意：三个角的方块是最关键的 - 一旦它们被遮挡，大多数扫描仪将无法看到代码。
I'm the author of the post on error correction.
For best results, you need to set the Error Correction to "H" that's "Hight".
That will allow up to 30% of the code to be damaged.
Note: The three corner squares are the most crucial - once they are obscured, most scanners won't be able to see the code.
