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 
     
       #define _AFXDLL  #include "stdafx.h" #include 
      
        #include 
       
         #include 
        
          #include 
         
           #include 
          
            #include 
           
             #include 
            
              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：
