iOS开发之银行卡号识别
作者:跟风的eassy
本文给大家分享ios开发之银行卡号识别功能,思路明确,需要的朋友参考下吧
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 详细解决链接地址
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) "_jpeg_get_large", referenced from: _alloc_large in opencv2(jmemmgr.o) _alloc_barray in opencv2(jmemmgr.o) "_jpeg_get_small", referenced from: _jinit_memory_mgr in opencv2(jmemmgr.o) _alloc_small in opencv2(jmemmgr.o) "_jpeg_mem_available", referenced from: _realize_virt_arrays in opencv2(jmemmgr.o) "_jpeg_mem_init", referenced from: _jinit_memory_mgr in opencv2(jmemmgr.o) "_jpeg_mem_term", referenced from: _jinit_memory_mgr in opencv2(jmemmgr.o) _self_destruct in opencv2(jmemmgr.o) "_jpeg_open_backing_store", referenced from: _realize_virt_arrays 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 。
