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:
