OpenCV & VS2010

1. OpenCV 패키지 다운로드
- http://sourceforge.net/projects/opencvlibrary/
(현재시점 2.4.7)

 

2. 시스템 환경변수 추가
- 변수이름 : OPENCV_BUILD
- 변수 값 : C:\openCV\build

 

3. 시스템 Path 변수에 추가
- %OPENCV_BUILD%\x86\vc10\bin;

 

4. VS2010 에서 Win32 console 프로젝트 생성 후 코드 추가

<MyOpenCV.cpp>

#include "stdafx.h"

// { for show_image()
#include <opencv\cv.h>
#include <opencv\highgui.h>
// for show_image() }

//
#include <opencv2/objdetect/objdetect.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>

#include <iostream>
#include <stdio.h>

using namespace std;
using namespace cv;

void show_image();
void camera_capture();
char key;

int _tmain(int argc, _TCHAR* argv[])
{
 //show_image();
 camera_capture();

 return 0;
}

void show_image()
{
 IplImage * image = cvLoadImage("Hydrangeas.jpg");

 cvShowImage("test image", image);
 cvWaitKey(0);

 cvReleaseImage(&image);
}

void camera_capture()
{
 cvNamedWindow("Camera_Output", 1);    //Create window   
 CvCapture* capture = cvCaptureFromCAM(CV_CAP_ANY);  //Capture using any camera connected to your system   
 while(1){ //Create infinte loop for live streaming        
  IplImage* frame = cvQueryFrame(capture); //Create image frames from capture       
  cvShowImage("Camera_Output", frame);   //Show image frames on created window       
  key = cvWaitKey(10);     //Capture Keyboard stroke       
  if (char(key) == 27){           
   break;      //If you hit ESC key loop will break.       
  }   
 }   
 cvReleaseCapture(&capture); //Release capture.   
 cvDestroyWindow("Camera_Output"); //Destroy Window
}

 

3. Project Property > C/C++ > General > Additional Include Directories
$(OPENCV_BUILD)\include

4. Project Property > Linker > General > Additional Library Directories
$(OPENCV_BUILD)\x86\vc10\lib

>> 32비트 운영체제에서 빌드 성공함

 

참고 1) VS2005 & 64비트 환경에서  $(OPENCV_BUILD)\x64\vc10\lib 로 설정한 뒤,
빌드하였더니 아래와 같은 링크 에러가 발생함.
