I am using opencv v3.4.2 with QT Creator IDE in C++.
I am trying to wrap an OpenCV matrix (Mat) as a numpyarray (PyObject *) so that I can pass it to a python script for processing. I am using the built-in wrapper functions from here: opencv/cv2.cpp. In particular this function:
PyObject* pyopencv_from(const Mat& m)
if( !m.data )
Py_RETURN_NONE;
Mat temp, *p = (Mat*)&m;
if(!p->u
So I have something like this:
Mat frame;
/*frame is populated*/
PyObject* pMat = opencv_from(frame);
The code compiles fine but when I call the function it hangs on m.copyTo(temp).
Does anyone have any advice on why this is not working ? Thanks.
