最近做了一个外包项目,在mt6261上实现二维码的展示和扫码功能。

拒绝造轮子,所以当然要选择开源库。

由于是mtk功能机平台,只支持c,所以c++和java什么的就不考虑了。

二维码的编码,选择了qrencode,这个移植比较简单,不多说。

二维码的扫描算法,走了一些弯路。一开始根据网上的扫描算法速度对比,选择了quirc。但是移植好了实际上机测试,完全不是那回事,速度慢的要死,十几秒没反应,机器直接重启了。查了下原因,才发现,原来它使用了浮点算法,而mt6261根本就不支持硬件浮点计算,是用的软浮点,怪不得这么慢!

最后选择了zbar,并进行了裁剪和优化,运行效果良好,不到0.5秒就能完成从扫描到识别出二维码的操作。

源码就不贴出来了,外包项目,代码还是要适当保密。

    We used to work together https://tppfitnessri.com/pharmacy/stmap_15nrpill.html?fincar.levitra.roxithromycin strepsils lidocaine It's dangerous, but I don't wear a helmet. A year and a half ago I was dragged under a bus and I thought someone was going to have to call my mother and tell her I'd died. But the only thing that was sticking out was my head, so a helmet wouldn't have helped. Luckily I wasn't injured.
