welcome to devnet

You need to provide a bit more information.
Qt version?
OS?
and possibly more.

genek1

qt 5.2.0
win 7

code:
@#include <stdio.h>
#include <iostream>
#include "opencv2/core/core.hpp"
#include "opencv2/features2d/features2d.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/calib3d/calib3d.hpp"
#include "opencv2/nonfree/nonfree.hpp"

using namespace std;
using namespace cv;

int main()
{
Mat image=imread("H:\programy\qt\Tools\QtCreator\bin\samochod\zdjecie.jpg"); //wczytuje obraz
imshow("Lena",image);//wyświetla obraz
waitKey();//wstrzymuje działanie programu
return 0;

On left side you find "Projects" and there under "run" you can check the run settings. The complete executable's name is given. Check it's presence.
Furthermore make sure that there is not a non-existing working directory given. IIRC this gives the same message back.

genek1

there are no exe in given catalog
working directory exists

Are you sure that can build successfully?

genek1

yes, there are no errors after building

Please check the compile output pane and see if there's any useful messages.

Here is these messages. I don't know if it's useful.

That is what google translater makes of the Polish text:

You might want to "rerun qmake" on the project and afterwards a "rebuild". You do that by right click on the project's name and choose those options.

Just to make you aware of, there is a "Polish forum":http://qt-project.org/forums/viewforum/44/ here on devnet. You might try it there as well. However, even so, there are some people on devnet talking Polish, it could be faster to get a solution in English.
If this is not Polish, I apologize, but I was letting google translate make the decision ;-)

Hi,

One more thing :

@image=imread("H:\programy\qt\Tools\QtCreator\bin\samochod\zdjecie.jpg");@

You forgot to escape the backslashes so your image won't be found

genek1

rerun qmake doesn't help

yes it's polish, but english forum is ok
