Use Eclipse on Ubuntu to create an OpenCV Project

My operating system is Ubuntu11.04Eclipse. The information is as follows: EclipseIDEforC/C ++ linuxpolicsversion: HeliosServiceRelease2Buildid: 20110218-0911. The specific steps are as follows: 1.

My operating system is Ubuntu 11.04

Eclipse information is as follows:

Eclipse IDE for C/C ++ Linux Developers
Version: Helios Service Release 2
Build id: 20110218-0911

The procedure is as follows:

1. First download the opencv-unixinstallation package opencv-2.3.0.tar.bz2 at http://sourceforge.net/projects/opencvlibrary/

2. Install cmake

Terminal run: sudo apt-get install cmake

3. Install cmake-qt-gui, a graphical interface of cmake

Terminal run: sudo apt-get install cmake-qt-gui

4. Compile and install opencv

(1) After cmake-qt-gui is installed, run cmake-gui on the terminal to open the graphical interface of cmake.

First, extract the downloaded opencv-2.3.0.tar.bz2, for example, to the OpenCV_2_3_src folder.

Create a new folder, such as OpenCV_2_3_build, as the directory to which the cmke build resides.

In the cmake-gui window, select OpenCV_2_3_src for the Browse Source and OpenCV_2_3_build for the Browse Build.

If the window turns red, click Configure and Generate as prompted.

(2) Open the terminal, cd to the OpenCV_2_3_build directory, and run

Make

It takes a long time.

After completion

Sudo make install

After completion, openCV is installed under usr/local.

Now openCV has been installed.

5. Create an openCV project in Eclipse

1) Open Eclipse, File --> New --> C ++ project. Create a Hello World project named firstOpencv.

2) Change the content in firstOpencv. cpp to the following, for example:

1. # Include "cv. h"
2. # Include
3. # Include
4. IntMain (IntArgc,Char* Argv [])
5. {
6. IplImage * img = cvLoadImage ("Image.jpg");
7. CvNamedWindow ("Image :", 1 );
8. CvShowImage ("Image :", Img );
9. CvWaitKey ();
10. CvDestroyWindow ("Image :");
11. CvReleaseImage (& img );
12.  Return0;
13. }
