问题
如何在处理图像像素时检测QR码？
图像可能是像素化的（低保真度），有噪点（一行中缺少或多出像素），模糊（抗锯齿）或者倾斜（图像倾斜）。简单地遍历像素似乎需要一些线检测，然后你可以计算出三个（或四个）不同角落之间预期块的数量。

How can I detect QR codes when processing the pixels of an image?
The image might be pixelated (low-fidelity), noisy (missing or extra pixels in a line), blurry (antialiasing), or be at an angle (image skew). Simply looping through the pixels seems like it would require some sort of line detection and then you could figure out a good calculate of the number of expected blocks between the three (or four) different corners.

你需要使用一个图像处理库来检测二维码。我过去使用过go-zxing，它是一个完全使用Go语言编写的库。
你需要熟悉标准库中的go image包。

You will need to use an image processing library to detect QRCodes. I’ve used go-zxing in the past which is 100% native go.
You will need to be familiar with the go image package that’s part of the standard library.
