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/** Copyright(C) 2010,Hikvision Digital Technology Co., Ltd * * File name��consoleMain.cpp* Discription��* Version ��1.0* Author ��panyadong* Create Date��2010_3_25* Modification History��*/#ifndef __APPLE__#include <stdio.h>#include <stdlib.h>#include <iostream>#include "GetStream.h"#include "public.h"#include "ConfigParams.h"#include "Alarm.h"#include "CapPicture.h"#include "playback.h"#include "Voice.h"#include "tool.h"using namespace std;int main(int argc,char* argv[]){//argv[]//argv[0] 相机IP地址//argv[1] 用户名//argv[2] 密码//argv[3] 功能选择 NET_DVR_Init();
