基本思想:给客户搞了个摄像头的人证比对历程，真艰辛；

本以为很简单的一个事情，最开始是人证比对，客户搞成了照片测试；我又搞成了眨眼测试，客户用上了手机播放视频；我又又搞成了手机检测，客户搞成了流媒体设备播放，深受其害，导入百度活体检测吧！

（1）、https://ai.baidu.com/ai-doc/FACE/4k37c1kj1 下载百度的C++ 活体检测SDK

 （2）、然后离线激活一下

（3）将下载的License.zip 导入许可文件F:\temp\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk-demo\windows\face_demo\License.zip，然后测试

 （4）修改一下百度提供的vs工程，进行活体检测，效果还可以啊~ （测试官方提供的demo）

测试了一张图片，测试结果

face-demo ---info--- rgb silent live test -- face 1:

(5)开始移植吧

添加头文件

D:\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk-demo\common\include
D:\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk\output\face_sdk\include
D:\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk-demo\third_party\zlib\windows\zlib\include
D:\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk-demo\third_party\libzip\include
D:\Opencv440\build\include\opencv2
D:\Opencv440\build\include

 添加库目录

D:\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk-demo\third_party\libzip\x64
D:\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk\output\face_sdk\x64
D:\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk-demo\third_party\zlib\windows\zlib\x64
D:\Opencv440\build\x64\vc15\lib

 添加lib库

face_sdk.lib
zip.lib

同时将官方提供的源码文件，拷贝到自己的工程中，先做一下删掉冗余文件吧~

 修改文件face_file_util.h，文件开头添加，同时拷贝新工程中

#pragma warning(disable:4996);

将opencv_world440.dll 、将D:\Baidu_Face_Offline_SDK_Windows_Cpp_V6.0\face-sdk-demo\windows\face_demo\x64\Release\*.dll都移动到可执行文件目录

将demo中模型拷贝到源码路径同时把官方的license.zip也拷贝到新工程中

align_rgb_float32_paddle.encrypted
detect_nir_int8_paddle.encrypted
silent_live_rgb_float32_paddle.encrypted
License.zip

修改新工程源码代码test_detect_rgb.h

 static StatusCode load_detect_ability(bdface::BDFaceInstance face_instance) {
        std::string detect_rgb_model_path = "F:\\sxj\\20210630\\ConsoleApplication2\\detect_nir_int8_paddle.encrypted";//添加绝对路径
        LOGI("loading rgb detect ability, model path: %s",
                detect_rgb_model_path.c_str());

修改新工程源码代码test_align_rgb_accurate.h

   static StatusCode load_align_ability(bdface::BDFaceInstance face_instance) {
        std::string align_rgb_accurate_model_path="F:\\sxj\\20210630\\ConsoleApplication2\\align_rgb_float32_paddle.encrypted";//添加绝对路径
        LOGI("loading accurate align rgb ability, model path: %s",
                align_rgb_accurate_model_path.c_str());

修改新工程源码代码test_silent_live_rgb.h

   static StatusCode load_silent_live_ability(bdface::BDFaceInstance face_instance) {
            std::string rgb_liveness_model_path = "F:\\sxj\\20210630\\ConsoleApplication2\\silent_live_rgb_float32_paddle.encrypted";//添加绝对路径
            LOGI("loading rgb live ability, model path: %s", rgb_liveness_model_path.c_str());

然后新工程测试活体检测demo就完成了，其它无用已经删掉
