ios open cv

大体有个思路

1. 捕捉银行卡图像,截取到字符区域

2. 最捕捉到的图像进行处理,去噪比,二值化,

3. 将银行卡号码区域进行切割划分,然后对比字符

opencv 安装失败,直接下载拖进 xcode 的话,会报以下错误

这里是 详细解决

undefined symbols for architecture x86_64:
 "_jpeg_free_large", referenced from:
   _free_pool in opencv2(jmemmgr.o)
 "_jpeg_free_small", referenced from:
   _free_pool in opencv2(jmemmgr.o)
   _self_destruct in opencv2(jmemmgr.o)

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

解决方法:

1.下载安装 libjpeg ,将

/opt/libjpeg-turbo/lib/libjpeg.a 

拷贝到项目中,然后添加几个 framework : corevideo.framework, assetslibrary.framework, coremedia.framework 。

以上所述是小编给大家介绍的ios开发之银行卡号识别,希望对大家有所帮助
