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：
