Python编程->混合编程（C++,python,opencv）实现

     对于一个程序宅来说，一直有想法把C++，opencv，python结合起来，python的并发性优点，opencv的图像处理算法的优点，C++的灵活，然后就开始了下面的旅程：

 

     配置版本：VS2008+Python2.7+OpenCV2.1.0

    

     源码：

OpenCV2.1.0  sampes里面的Python例程camera.py：

     


将其放到VS2008的例子python的工程目录下：



然后就开始写代码了：

#include "stdafx.h"
#include "python.h"
#include <tchar.h>
#define _AFXDLL
#include "stdafx.h"
#include <stdio.h>
#include <string>
#include <iostream>
#include <fstream>
#include <cstring>
#include <afx.h>
#include <iostream>
using namespace std;
#pragma comment (lib,"python27.lib")

int test1()
{
Py_Initialize();

CString strPath;

GetCurrentDirectory(MAX_PATH,strPath.GetBuffer(MAX_PATH));

char ch[BUFSIZ];
WideCharToMultiByte( CP_ACP, WC_COMPOSITECHECK, (strPath.GetBuffer(strPath.GetLength() + 1)), -1, ch, sizeof(ch), NULL, NULL );
;

strPath.ReleaseBuffer();

string tmpStr;
cout << ch << endl;
int len = strlen(ch);
string fileName = "\\camera.py";
for( int i = 0; i < int(fileName.length()); i++)
ch[len++] = fileName[i];

ch[len] = '\0';
cout << ch << endl;
PyObject *pyfile = PyFile_FromString(ch,"r");
if(pyfile==NULL)
{
printf("exit 1");
system("pause");
return 1;
}
FILE *f = PyFile_AsFile(pyfile);
if(f==NULL)
{
printf("exit 2");
system("pause");
return 1;

}
PyRun_AnyFileEx(f,"camera.py",0);

Py_Finalize();

}
int main()
{
test1();
system("pause");
}

点击Run后，打开摄像头如下：



调用如下：
