How to setup OpenCV ?

By | July 24, 2008

As I mentioned before, OpenCV is an open source library of computer vision in C/C++. Before you can use it, of course you must have Visual C/C++ or Visual.Net installed in your PC. Me, I’m using Visual C++ 6.0 for my project.

The following are the procedures to setup OpenCV:

  1. Download the OpenCV installation file from here. Find the latest version.
  2. Run (double click) the installation file. After completed, you will get OPENCV icon menu in your PROGRAM.
  3. Make a linking in the system PATH to OpenCV DLLs files, using the below steps:
  • Click My Computer –> Properties –> Advanced –> Environment Variables –> Systems variable –> highlight PATH –> Edit.
  • Add “C:\Program Files\OpenCV\bin” to PATH. The location of OpenCV DLL files might be differentEach different path file is separated by semicolon (;)
  • If your OpenCV is already opened, you should close it then open again to take effect of the new path.

4. Customize the GLOBAL OPTIONS- In your OpenCV window, click Tools –> Options and select Directories tab

  • Select directories for Include files, then add four OpenCV directories as show in the figure.
  • Also add OpenCV directories for Library & Search files (see the figure)


Now your OpenCV is ready for creating your own project. How to develop a project using OpenCV? Be patient for the next tutorial.
