Matlab可以通过与C/C++混合编程的方式来调用Opencv。在混合编程中,关键是使用mexFunction函数来实现Matlab与C/C++的交互。mexFunction函数的基本形式为void mexFunction(int nlhs, mxArray *plhs\[\],int nrhs, const mxArray *prhs)。\[1\]
在调用Opencv之前,需要将数据从Matlab读入C++,然后经过C++函数运算后再将结果返回给Matlab。这个过程是非常重要的。可以参考一些博文和教程来学习如何在Matlab中调用Opencv,如博文"matlab调用C程序"和"Matlab与C++混合编程(依赖OpenCV)"。\[2\]
在具体实现中,需要设置一些编译选项和链接选项,以确保Matlab能够正确调用Opencv。例如,如果Opencv解压在F盘,而自己编写的mexFunction保存为test.cpp,那么可以将编译选项CPPFLAGS设置为'-O -DNDEBUG -I.\ -IF:\opencv\build\include -IF:\opencv\build\include\opencv -IF:\opencv\build\include\opencv2',链接选项LDFLAGS设置为'-LF:\opencv\build\x64\vc12\lib',库选项LIBS设置为'-lopencv_core249 -lopencv_highgui249 -lopencv_imgproc249'。如果是64位系统,还需要在CPPFLAGS中添加'-largeArrayDims'选项。然后将需要编译的文件test.cpp添加到compile_files中。\[3\]
通过以上步骤,就可以在Matlab中成功调用Opencv了。
