hi, Thank you for this excellent SFM example. I download the code and run it in matlab (R2018a),then I find that the error at "dense matching",I don't know why,please help me.thanks @jianxiongxiao image

I rebuilt priority_queue_1.0 by running pq_demo.m in MATLAB before running SFMedu2.m and solved this problem.

You may install MATLAB Support for MinGW-w64 C/C++ Compiler first, and replace mex -v CXXFLAGS='$CXXFLAGS -fpermissive' with mex in pq_demo.m. Suppose you are using Windows.

holy3kill commented 4 years ago

This crash is caused by priority_queue_1.0/pq_push.cpp, if you use vs2017 and Matlab R2019b, you should alter the source code like that:

void retrieve_heap( const mxArray* matptr, MaxHeap<double>* & heap){

    // retrieve pointer from the MX form

    double* pointer0 = mxGetPr(matptr);

    // check that I actually received something

    if( pointer0 == NULL )

        mexErrMsgTxt("vararg{1} must be a valid priority queue pointer\n");

    // convert it to "long" datatype (good for addresses)

    long pointer1 = static_cast<long> (pointer0[0]);

    // convert it to "KDTree"

     heap = reinterpret_cast<MaxHeap<double>*> (pointer1);

    // check that I actually received something

    if( heap == NULL )

        mexErrMsgTxt("vararg{1} must be a valid priority queue pointer\n");
}

Then run pq_demo.m and rebuild mex file, enjoy it. This crash tell us use static_cast and reinterpret_cast is better than C type conversion.........

你用的什么编译器？我的可以通过编译的啊，如果不行的话你改为这样试试： long pointer1 = (long) (pointer0[0]);

是因为使用VS编译器的原因，换成MinGW编译器，然后在 pq_demo.m里用 mex -v CXXFLAGS='$CXXFLAGS -fpermissive' 代替 mex，运行编译就可以，亲测可以解决。 谢谢楼上各位的解答

This crash is caused by priority_queue_1.0/pq_push.cpp, if you use vs2017 and Matlab R2019b, you should alter the source code like that:

void retrieve_heap( const mxArray* matptr, MaxHeap<double>* & heap){

    // retrieve pointer from the MX form

    double* pointer0 = mxGetPr(matptr);

    // check that I actually received something

    if( pointer0 == NULL )

        mexErrMsgTxt("vararg{1} must be a valid priority queue pointer\n");

    // convert it to "long" datatype (good for addresses)

    long pointer1 = static_cast<long> (pointer0[0]);

    // convert it to "KDTree"

     heap = reinterpret_cast<MaxHeap<double>*> (pointer1);

    // check that I actually received something

    if( heap == NULL )

        mexErrMsgTxt("vararg{1} must be a valid priority queue pointer\n");
}

Then run pq_demo.m and rebuild mex file, enjoy it. This crash tell us use static_cast and reinterpret_cast is better than C type conversion......... 请问出现这样的错误是什么原因呢？

错误使用 mex C:\Users\29085\Downloads\SFMedu-master\denseMatch\priority_queue_1.0\pq_create.cpp: In function 'void mexFunction(int, mxArray, int, const mxArray)': C:\Users\29085\Downloads\SFMedu-master\denseMatch\priority_queue_1.0\pq_create.cpp:52:30: error: cast from 'MaxHeap*' to 'long int' loses precision [-fpermissive] pointer_to_tree[0] = (long) pq; ^

出错 pq_demo (line 9) mex pq_create.cpp;

I am having the same problem. have you solved it yet ?

I think the problem is with loss of precision when storing a pointer in a long instead of long long (which might be due to the difference in running on 32 vs 64 bit systems but I'm not sure). I was able to solve the issue with the following steps (you can also check my fork of the repo for the working code):

Switch to MinGW64 Compiler for C++ (make sure you run mex -setup C++)

Replace line 52 in pq_create.cpp: pointer_to_tree[0] = (long) pq; with: pointer_to_tree[0] = (long long) pq;

Replace all instances of the following in pq_delete.cpp, pq_pop.cpp, pq_push.cpp, pq_size.cpp, and pq_top.cpp: long pointer1 = (long) pointer0[0]; with: long long pointer1 = (long long) pointer0[0];

不行啊，编译器也换了，代码也改成reinterpret_cast，但是pq_push就是会导致matlab崩溃，绝望

可以可以，我从你的git仓库拉取的代码能够直接使用，谢谢！

您好，请问一下我刚下载的这个代码，如何解决这个问题？您可以分享一下吗
