loading intrisinc parameters

[zlc]

In OpenCv in order to load the intrisinc parameters from an xml file i use:
CvMat *intrinsic = (CvMat*)cvLoad("Intrinsics.xml");

how it would be in EmguCV?

To load an OpenCV format XML matrix file, you can do

Code: Select all

IntPtr mat = CvInvoke.cvLoad("Intrinsics.xml", IntPtr.Zero, null, IntPtr.Zero);
Matrix<double> intrinsicMatrix = new Matrix<double>(3, 3);
CvInvoke.cvCopy(mat, intrinsicMatrix, IntPtr.Zero);
CvInvoke.cvRelease(ref mat);

I am writing it in C# syntax, it should be easy to translation it to Manage C++.

I rewrote it to c++/cli but have some problems.

Code: Select all

IntPtr mat = CvInvoke::cvLoad("Intrinsics.xml", IntPtr::Zero, NULL, IntPtr::Zero);

In this line i get error: cannot convert parameter 3 from 'int' to 'System::String ^'
So i convert it to

Code: Select all

IntPtr mat = CvInvoke::cvLoad("Intrinsics.xml", IntPtr::Zero, NULL.ToString(), IntPtr::Zero);

next problem in line:

Code: Select all

Matrix<double> intrinsincMatrix = gcnew Matrix<double>(3, 3);

in this line i get error: error C2664: 'Emgu::CV::Matrix<TDepth>::Matrix(cli::array<Type> ^)' : cannot convert parameter 1 from 'Emgu::CV::Matrix<TDepth> ^' to 'cli::array<Type> ^'

so it obvious that the code

Code: Select all

CvInvoke::cvCopy(mat, intrinsicMatrix, IntPtr.Zero);

can't be compiled

And in the line

CvInvoke.cvRelease(ref mat); in c++/cli i don't have cvRelease method

Please help me to deal with this.

CvMat *mat = (CvMat*)cvLoad("Intrinsics.xml");
Matrix<double>^ intrinsicMatrix = gcnew Matrix<double>(3, 3);
cvCopy(mat, intrinsicMatrix.Ptr.ToPointer());
cvReleaseMat(& mat);[/code]
