matlab调用opencv函数的配置

环境：

VS2010 活动解决方案平台x64

WIN 8.1

Opencv 2.4.3

Matlab 2012a

1、  首先保证vs2010能正确调用opencv函数，

2、  Matlab中选择编译器，操作如下：

打开matlab2012，输入mex –setup，出现如下提示：

Welcome to mex -setup.  This utility will help you set up

a default compiler.  For a list of supported compilers, see

http://www.mathworks.com/support/compilers/R2012a/win32.html

Please choose your compiler for building MEX-files:

Would you like mex to locate installed compilers [y]/n?

输入y，出现如下提示：

Select a compiler:

[1] Lcc-win32 C2.4.1 in C:\PROGRA~1\MATLAB\R2012a\sys\lcc

[2] Microsoft Visual C++ 2010 in C:\Program Files\Microsoft Visual Studio 2010

[0] None

Compiler:

输入，出现如下提示：

Please verify your choices:

Compiler: Microsoft Visual C++ 2010

Location: C:\Program Files\Microsoft Visual Studio 2010

Are these correct [y]/n?

输入y

出现如下提示，表明成功：

***************************************************************************

Warning: MEX-files generated using Microsoft Visual C++ 2010 require

that Microsoft Visual Studio 2010 run-time libraries be

available on the computer they are run on.

If you plan to redistribute your MEX-files to other MATLAB

users, be sure that they have the run-time libraries.

***************************************************************************

Trying to update options file: C:\Documents and Settings\zhangjing\Application Data\MathWorks\MATLAB\R2012a\mexopts.bat

From template:              C:\PROGRA~1\MATLAB\R2012a\bin\win32\mexopts\msvc100opts.bat

Done . . .

**************************************************************************

Warning: The MATLAB C and Fortran API has changed to support MATLAB

variables with more than 2^32-1 elements.  In the near future

you will be required to update your code to utilize the new

API. You can find more information about this at:

http://www.mathworks.com/help/techdoc/matlab_external/bsflnue-1.html

Building with the -largeArrayDims option enables the new API.

**************************************************************************

3、  配置一些目录

在matlab中，输入mex –v

下面会有显示：

-> Default options filename found in C:\Documents and Settings\zhangjing\Application Data\MathWorks\MATLAB\R2012a

----------------------------

->    Options file           = C:\Documents and Settings\zhangjing\Application Data\MathWorks\MATLAB\R2012a\mexopts.bat

MATLAB                 = C:\PROGRA~1\MATLAB\R2012A

->    COMPILER               = cl

->    Compiler flags:

COMPFLAGS           = /c /GR /W3 /EHs /D_CRT_SECURE_NO_DEPRECATE /D_SCL_SECURE_NO_DEPRECATE /D_SECURE_SCL=0 /DMATLAB_MEX_FILE /nologo /MD

OPTIMFLAGS          = /O2 /Oy- /DNDEBUG

DEBUGFLAGS          = /Z7

arguments           =

Name switch         = /Fo

。。。。。。。。。（此处省略一些）

选中上面Options file=后面的部分，右键->Open Selection，打开mexopts.bat

找到下面部分，增加红色的部分

set MATLAB=%MATLAB%

set VSINSTALLDIR=C:\Program Files\Microsoft Visual Studio 2010

set VCINSTALLDIR=%VSINSTALLDIR%\VC

rem In this case, LINKERDIR is being used to specify the location of the SDK

set LINKERDIR=C:\Program Files\Microsoft SDKs\Windows\v7.0A\

set PATH=%VCINSTALLDIR%\bin;%VCINSTALLDIR%\VCPackages;%VSINSTALLDIR%\Common7\IDE;%VSINSTALLDIR%\Common7\Tools;%LINKERDIR%\bin;%MATLAB_BIN%;%PATH%

在matlab当前目录下建立cpp文件（简单方法，txt改后缀为cpp），vs打开敲入代码，代码需要是Matlab的C语言接口风格，函数内部调用OpenCV函数演示功能，简化后的代码：程序命名为useOpenCV.cpp保存。

#include"mex.h"

#include     "cv.h"

#include    "highgui.h"

using namespacecv;

voidmexFunction (int nlhs, mxArray *plhs[], // 输出参数个数，及输出参数数组

int nrhs, const mxArray *prhs[]) // 输入参数个数，及输入参数数组

{

char name[256];

int buflens =mxGetNumberOfElements(prhs[0]);

mxGetString(prhs[0], name, buflens+1);

if(!mxIsChar(prhs[0]))

{

mexErrMsgTxt("First parameter must be string/n");

}

mexPrintf(name);

IplImage * img = cvLoadImage(name, 1);

if(img->imageData == NULL)

{

mexErrMsgTxt("Error in image/n");

}

cvNamedWindow("1",1);

//imshow("1",mat);

cvShowImage("1",img);

cvWaitKey(0);

return;

}

5 在matlab里输入 mexuseOpenCV.cpp编译。

6 在matlab里输入命令调用编译好的文件：useOpenCV(‘lena.bmp’);即可调用。注意，lena.bmp图片放在当前文件下。
