Level 0-EmguCV Installation Guide for 32-bit Windows users

June 8, 2011

LEARNING OBJECTIVE:


NOTE: FOR THOSE WHO USE 64-bit Windows
please FOLLOW THIS TUTORIAL INSTEAD

PART 1- SETUP THE REQUIRED TOOLS::

1. Make sure you have Visual Studio C# 2008 installed (any edition, I’ve used Visual C# 2008 Express Edition and Visual Studio 2008 and 2010 Professional Editions on my 32-bit Win 7 Ultimate. So far so good.)

2. Download Emgu CV installer. You could use any latest vesion but i can't guarantee that my tutorials will work cent per cent same on it too. select your desired version here, or follow with mine below, I used the following version:
libemgucv-windows-x86-2.2.1.1150.exe - Download it from here

3. Install Emgu CV to windows directory.( if you're using the same version as me, then copy-paste the following Path EXACTLY as in below fig, To avoid any incompatibility with my tutorials.):

C:\Emgu\emgucv-windows-x86 2.2.1.1150\     
   
note: 'emgucv-windows-x86 2.2.1.1150' is the name of the setup file. Depending on the version you're using, if it's different than mine, adjust it according to YOUR setup file name please)

Set Path of EmguCv at installation

 

PART 2- Run the Examples!--checking if we correctly configured our tools:

4. Go to the VS2008 folder in Emgu, path is as follows:
 C:\Emgu\emgucv2.2.1.1150\Solution\VS2008

and open Emgu.CV.Example.sln, (click OK to any error messages(if any) when they appear while trying to open the .sln, they're for Visual Basic files, C# files will load normally)

Note: before you run any example; you should first replace the missing reference files with their correct n current paths. The following explains how to:


A.Replace/add the path of project References:
4. When the Project solution is opened, first expand the project’s “References” from the “solution explorer” at right side of the IDE. Then Delete all the Emgu.CV.xxx.dll files in the reference if it has a yellow exclamation mark on it indicating that file is missing from path specified. REMEMBER which ones you deleted, because now we will add them.

    i. Right-click References and select "add reference"

    ii. Select the Browse tab
   
    iii. To add a .dll file, browse to where the required .dll files are located. For our tutorial, our required .dll files are in EmguCV’s bin folder at the following path:        C:\Emgu\emgucv2.2.1.1150\bin

     iv. Select the .dll file you want to add. Click ok. (you can select and add multiple .dll files at once by holding ctrl+click as shown in level-1 Tutorial)

The files should be added by now! see the Emgu.CV  and Emgu.Util under References where the red arrow is pointing in the Solution Explorer? that's it! :)

B. Build the solution:
5. OK so we’ve checked if our referenced dlls were missing and took care of the matter. Now let’s get down to our main point. That’s right! Let’s see the output already!
For that, Right-click the Solution 'Emgu.CV.Example' in the solution explorer and select Build solution. Then once it is built, click the debug button (green play button), now you should see a window with “hello world” pop up. I did. Maybe you will too if all went well so far :)



6. Congratulations! You just successfully configured your first EmguCV project!
After this is done, all the other EmguCV Examples are ready to be built and be debugged. They will be present at the following path C:\Emgu\emgucv2.2.1.1150\Emgu.CV.Example

Hi Mahvish

I am using VS 2010 on windows 7 x64. After downloading and installing when trying to build the example project I get 17 linking errors from the C++ CPlusPlus project. Any suggestions?

Thanks a lot for this tutorial. It provides the beginners ( like me :) ) with clear explanation.

Well, I have 2 problems here I am facing:
1. when I try to run an example, an error pops up saying that nvcuda.dll is missing.
I searched the internet for that dll file and installed it. However, the program is not working after the installation.

2. I have copied and pasted the opencvXX.dll files to the debug directory, But still, the program is not working.

more info:
Windows 7 x64 bit.
Downloaded http://sourceforge.net/projects/emgucv/files/emgucv/2.4.2/libemgucv-windows-x64-gpu-2.4.2.1777.exe/download

Nice emgucv tutorial that i've seen.

Thank you much!

Excellent job! You really have a passion to transfer your knowledge to others. Keep up the good work.

Hi Mahvish,

You work is highly appreciable. Thank you for the tutorial, i am doing my final year project as face detection recognition, your tutorial helping me to learn more about EMGUCV abilities and how to use it. Thank you again :-)

You are very kind thank you;-*

i am using win 7 64 bit and i have downloaded x64 installer when i run example of Hello World i get an error of The type initializer for 'Emgu.CV.CvInvoke' threw an exception.... plz hepl anyone.. :(

Thanks man...and it works!

"I am using VS 2010 on windows 7 x64. After downloading and installing when trying to build the example project I get 17 linking errors from the C++ CPlusPlus project. Any suggestions?" - I just ignored it and instead of running the entire solution (.sln), open just the .csproj projects, should work fine. Some of them were .NET 2.0 and needed to update them, but overall awesome tutorial, thank you so much!
