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");}
