  1. 大家的问题都集中在放大上,这个会集中修改。
  2. 对于特殊的二维码可以提供图片,我会调整参数,尝试与微信的识别靠齐。
  3. 货架二维码是什么样的呢?没有具体的概念,如果可以的话也可以提供实际的图片,如果想研究的话,你可以专门去做这方面的处理,比如颜色过滤

2.第二点中的二维码就是手机和二维码没有对正,手机可能在二维码的左上方扫描
3.货架二维码是我们把货架编了个号,每个货架格子有个二维码,所以经常会很难对正,因为有的格子高有的低

两个图片目标都是为了扫H9,微信都可以扫描出来,而且速度可以接受,你试着用demoapp扫下,第二个可能能扫出来,但是速度很慢,第一个我没扫出来过。生活中这个是很常见的需求,用户不懂这个,不会对正,所以如果各个角度的二维码都可以认识的话,就方便多了。

优化了一版,效果虽然还比不上微信,不过可以先试下,我这边可以顺利扫出第二个。

谢谢大神做的努力,我这边下载下demo试试,我觉得得在变型码校正代码上下功夫,处理逆光,高光部分过多的问题其实没有那么重要。

相比于zxing ,zbar对于倾斜角度的二维码,还有变形的二维码 ,基本都能识别出来

第一张图H9的二维码,第二章图H9 R10, 用zbar 都可以识别出来
其他的 zbar识别不出来,用微信也识别不出来,意见可以参考下zbar的

@maybelife 我去看下zbar的逻辑,感觉又是一个坑😂。。
