Qt编写人脸识别人脸比对证件识别

项目需要，将刷卡抓拍到的图像和身份证图像进行比对，判断出是否为同一人，用opencv或者离线SDK做，效率低识别率低，索性直接用web api，我采用的是face++，据说支付宝刷脸也是用的该公司的库，我测试了下，准确度100%。特意花了两天时间写了个类，将处理封装了下。该类已经集成在QFramework中。返回json数据解析使用QScript解析，没有使用qt5中的json类，因为我的目标运行平台为qt4.8。
运行效果：

    * face++ 证件识别+人脸识别+人脸比对等功能类 作者:feiyangqingyun(QQ:517216493) 2017-9-16
    * 1:可识别身份证正面信息+背面信息
    * 2:可识别银行卡信息
    * 3:可识别驾驶证+行驶证信息
    * 4:可进行人脸识别,人脸比对
    * 5:可设置请求地址+用户密钥+应用密钥
    * 6:直接传入图片即可,信号返回,毫秒级极速响应
    * 7:通用Qt4-Qt5,windows linux 嵌入式linux

这是线上是别的，有离线识别的没

liudianwu 2018-04-23 20:28
最新的对应应用界面，使用嵌入式linux离线版本。运行在imx6+树莓派+香橙派+全志H3等板上。

大侠，离线版用的opencv嘛，识别成功率怎么样？

大神，离线版本的是用opencv来做的吗？有用树莓派来测试过吗？
