3. OpenCV Fehler

OpenCV Fehler

  • D

    Hi Leute,
    Ich wollte mal ein bisschen mit OpenCV 2.4.0 unter C++ rumprobieren. Also OpenCV nach "C:\Program Files\OpenCV" entpackt und mehr nicht(vielleicht steckt hier ja schon der Fehler). Nun wollte ich das Programm C++ Beispielprogramm "camshiftdemo.cpp" (Code:)

    #include "opencv2/video/tracking.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"

#include <iostream>
#include <ctype.h>

bool selectObject = false;
int trackObject = 0;

Point origin;
Rect selection;
int vmin = 10, vmax = 256, smin = 30;

void onMouse( int event, int x, int y, int, void* )
{
    if( selectObject )
    {
        selection.x = MIN(x, origin.x);
        selection.y = MIN(y, origin.y);
        selection.width = std::abs(x - origin.x);
        selection.height = std::abs(y - origin.y);

        selection &= Rect(0, 0, image.cols, image.rows);
    }

    switch( event )
    {
    case CV_EVENT_LBUTTONDOWN:
        origin = Point(x,y);
        selection = Rect(x,y,0,0);
        selectObject = true;
        break;
    case CV_EVENT_LBUTTONUP:
        selectObject = false;
        if( selection.width > 0 && selection.height > 0 )
            trackObject = -1;
        break;
    }
}

    testen, da mich hauptsächlich Bewegungserkennung(Webcam) usw. interessiert. Ich versuche das ganze mit MinGW zu kompilieren(Code:)

    SET BINDIR=%~dp0
CD /D "%BINDIR%"
g++ camshiftdemo.cpp -I "C:\Program Files\OpenCV\build\include" -L "C:\Program Files\OpenCV\build\x86\mingw\lib"
pause

    aber ich erhalte die Fehlermeldung:
