1. Install Visual studio 2013 community version which is free to use for personal usage.
2. Setup the debugger follow the instruction in http://doc.qt.io/qtcreator/creator-debugger-engines.html. On windows can go to link
https://msdn.microsoft.com/en-us/library/windows/hardware/ff551063(v=vs.85).aspx to download and install Debugging Tools for Windows.
3. Install OpenCV 3.0
4. Use CMake create OpenCv 2013 solutions.
5. Build OpenCv project, target platform choose x86. ( OpenCv 3.00 cannot build success if target x64 platform)
6. Install QT. Download qt-opensource-windows-x86-msvc2013-5.5.1.exe and install. (Can not use qt-opensource-windows-x86-msvc2013_64-5.5.0.exe, because no 64 bit dynamic library available)
7. Create a QTConsole project in QT creator. Add the below blue code to the QTConsole.pro file. (Please change the include path and library path to the real path on your PC)
QT += core
QT -= gui
TARGET = QTConsole
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
INCLUDEPATH += C:/Users/shenxiao/Downloads/opencv/build/include
LIBS += -LC:/Tools/OpenCV_MyBuild/lib/Debug \
opencv_core300d.lib \
opencv_highgui300d.lib \
opencv_imgproc300d.lib \
opencv_features2d300d.lib \
opencv_calib3d300d.lib \
opencv_videoio300d.lib \
opencv_video300d.lib \
opencv_imgcodecs300d.lib\
SOURCES += main.cpp8. Change the main.cpp to code as below.
#include <QCoreApplication>
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv/cv.h"void Test()
{
cv::Mat mat;
mat = cv::imread("C:\\Test\\QTConsole\\img.jpg");
if ( mat.empty() )
return;
cvNamedWindow("hello");
cv::imshow("hello",mat); cvWaitKey(); cv::destroyWindow("hello");
}int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
Test();
printf("hello world");
getchar();
return a.exec();
}
9. Run QMake, build and then press F5 to run with debug.
If the application can not start, then need to copy all the opencv build .dll files to the debug folder, together with the exe file.
