python 调用海康linux下demo的可执行程序，设置回调，实现人脸识别 以及实现抓拍功能

python使用os.system调用海康
 

CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/consoleDemo下的demo生成的可执行文件，

生成文件为sdkTest python调用代码如下：

def callAndRunCpp():###这个是人脸对比的python接口，
    restartTime = 0
    while True:##人脸相机对比接口有时候会意外退出，因此退出后我就重启
        restartTime += 1
        print("启动c++可执行文件来获取相机的信息,第%d次启用",restartTime)
        os.system(
            r'"/home/caobin/chike/chike/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/consoleDemo/linux64/lib/sdkTest" '
            r'"192.168.1.64" 8000 "admin" "guoji123" 3')
        time.sleep(2)

#####抓图调用语句

 os.system(
            r'"/home/caobin/chike/chike/CH_HCNetSDK_V5.2.7.4_build20170606_Linux64/consoleDemo/linux64/lib/sdkTest" '
            r'"192.168.1.64" 8000 "admin" "guoji123" 4')

//C++方面，将main函数带上参数，然后根据传进来的参数对相机进行操作,对C++consoleMain的修改如下

//这里我主要实现的是人脸对比和抓拍图片两个功能，其中人脸对比结果直接存到了数据库，抓拍图片则是以时间格式直接保存的图片
