Win7上Matlab中使用Visual Studio 2010编译Opencv的Mex文件

Win7下Matlab中使用Visual Studio 2010编译Opencv的Mex文件

编译命令：

mex testmex.cpp -I"C:\opencv24\opencv\build\include" -I"C:\opencv24\opencv\build\include\opencv" -L"C:\opencv24\opencv\build\x64\vc10\lib" -lopencv_core241 -lopencv_highgui241 -lopencv_imgproc241

这里关键是正确指定库文件查找路径

 

testmex.cpp内容

//file: testmex.cpp
//编译命令：mex testmex.cpp -I"C:\opencv24\opencv\build\include" -I"C:\opencv24\opencv\build\include\opencv" -L"C:\opencv24\opencv\build\x64\vc10\lib" -lopencv_core241 -lopencv_highgui241 -lopencv_imgproc241
#include <iostream>
#include "mex.h"
#include "opencv2/opencv.hpp"

using namespace std;
using namespace cv;

void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
    try
    {
        mexPrintf("come1\n");      
        Mat src = cv::imread("d:\\bird.jpg", CV_LOAD_IMAGE_GRAYSCALE), dst;       
        threshold(src, dst, 128.0, 255.0, CV_THRESH_BINARY);
        
        imshow("Source", src);
        cv::imshow("Result", dst);
        cv::waitKey(0);
        cvDestroyAllWindows();
        mexPrintf("over\n");
    }
    catch(const cv::Exception& ex)
    {
        char err[512];
        sprintf(err, "Error:%s", ex.what());
        mexPrintf(err);
    }
    mexPrintf("ok");
}
