OPENCV2.4.13+VS2012 development environment Configuration and example

1. Download and install the OpenCV SDK

Download page for OPENCV official website: http://opencv.org/downloads.html find the corresponding OpenCV for Windows version download. Currently (2016/07/02) the latest version of the official website is released in 2015/12/21, Version 3.1.0, the latest release is the 2016/05/19 day of version 2.4.13.

Version 3.1.0 only has a 64-bit development package and does not (and does not know the future) support the 32-bit compilation environment, which uses version 2.4.13.

After the download is complete, double-click "Opencv-2.4.13.exe" to eject the Install (Unzip) dialog box:

Select the installation path, here is the use of "D:\ProgramFilesD", click "Extract" after the start of decompression;

It is important to note that there is no additional "OpenCV" folder in the installation directory, OpenCV the root directory extracted from the installation package is "OpenCV".

2. Native environment variables and path configuration

Click the Start menu, right-click Computer, properties, advanced system settings, and environment variables, open the Environment Variable Settings dialog box.

Create a new variable in the user variable OPENCV, variable value: D:\ProgramFilesD\opencv\build;

Create a new variable in the user variable path, variable value: D:\ProgramFilesD\opencv\build\x86\vc11\bin;

There may be a question here: The compiler is VS2012, and the value of the variable should not be xx\vc12\bin. Note that in the OPENCV configuration, vc11 that corresponds to VS2012,VC12 corresponds to VS2013.

Another thing to be concerned about is whether the above variable value should be x86 or x64. Here x86 or x64 choice with your computer is 32-bit or 64-bit unrelated, vs2012 compilation environment by default using Win32 compiler, so select x86.

Edit (or add) the path variable in the system variable, the value of the variable: D:\ProgramFilesD\opencv\build\x86\vc11\bin, note to use the English input semicolon and the previous path is separated, after the addition of the need to restart or log off the computer, The environment variable will not take effect.

3. IDE Project Properties Configuration

Create a new WIN32 console application, name the project name MYFIRSTOPENCV, and select an empty project in the following options:

Right-click Myfirstopencv Project, add New item, select C + + file (. cpp) in the Pop-up dialog box, add source file, name MyFirstOpenCV.cpp:

In the View Directory drop-down menu, open the property manager in the property manager's Debug| On the Win32 directory, click Select Add New Project property sheet, create a new property sheet, and name it Opencv_debug_setting.props.

Double-click to open the property sheet opencv_debug_setting.props. Select the common Properties->vc++ directory and add 3 directories to the containing directory:

D:\ProgramFilesD\opencv\build\include\opencv2

D:\ProgramFilesD\opencv\build\include\opencv

D:\ProgramFilesD\opencv\build\include

Also in the VC + + directory, add 1 directories in the Library directory:

D:\ProgramFilesD\opencv\build\x86\vc11\lib

Add a library file to an additional dependency by selecting the additional dependency, input----linker, general properties, and so on:

Opencv_ml2413d.lib

Opencv_calib3d2413d.lib

Opencv_contrib2413d.lib

Opencv_core2413d.lib

Opencv_features2d2413d.lib

Opencv_flann2413d.lib

Opencv_gpu2413d.lib

Opencv_highgui2413d.lib

Opencv_imgproc2413d.lib

Opencv_legacy2413d.lib

Opencv_objdetect2413d.lib

Opencv_ts2413d.lib

Opencv_video2413d.lib

Opencv_nonfree2413d.lib

Opencv_ocl2413d.lib

Opencv_photo2413d.lib

Opencv_stitching2413d.lib

Opencv_superres2413d.lib

Opencv_videostab2413d.lib

OK, at this point, the VS2012 environment configuration OpenCV2.4.13 work has been completed, for the creation of the OPENCV project, only need to add the project's property configuration, no longer need to step-by-step configuration.

Method: First save the project's property profile Opencv_debug_setting.props to the alternate folder, the path to this property profile in this project is:

D:\VS2012Test\MyFirstOpenCV\MyFirstOpenCV

Then in the newly created project, add the Opencv_debug_setting.props property sheet in the property manager:

4.OpenCV Project Testing

Finally, let's test whether the configuration is OK.

Add the following code to the program's source file, MyFirstOpenCV.cpp file, to display a picture in the window:

<pre name= "code"  class= "CPP" > #include  <iostream>   #include <core /core.hpp>   #include
