no suitable conversion function from "CvTermCriteria" to "int" exists

Question

How could I solve the error?

I use program that made for OpenCV 2.x but I compile it on OpenCV 3.0, and error appeared. I change CvTermCriteria to TermCriteria::TermCriteria but thats not working. How could I change CvTermCriteria to be int?

Hope anyone could help me. Thanks

Error appeared at this part:

cvStereoCalibrate( &_objectPoints, &_imagePoints1, &_imagePoints2, &_npoints,&_M1calib, &_D1, &_M2calib, &_D2,imageSize, &_R, &_Tcalib, &_E, &_F, 
    cvTermCriteria(CV_TERMCRIT_ITER+CV_TERMCRIT_EPS, 100, 1e-5),
    CV_CALIB_FIX_ASPECT_RATIO+CV_CALIB_ZERO_TANGENT_DIST + CV_CALIB_SAME_FOCAL_LENGTH );

This is the source code:

//--------------Compute for calibration-------------------
    N = n_boards*n;
    objectPoints.resize(N);
    for( i = 0; i < ny; i++ )
        for(j = 0; j < nx; j++ )   objectPoints[i*nx + j] = cvPoint3D32f(i*squareSize, j*squareSize, 0);
    for( i = 1; i < n_boards; i++ ) copy( objectPoints.begin(), objectPoints.begin() + n, objectPoints.begin() + i*n );
    npoints.resize(n_boards,n);

    CvMat _objectPoints = cvMat(1, N, CV_32FC3, &objectPoints[0] );
    CvMat _imagePoints1 = cvMat(1, N, CV_32FC2, &points[0][0] );
    CvMat _imagePoints2 = cvMat(1, N, CV_32FC2, &points[1][0] );

        cvInitUndistortRectifyMap(&_M1calib,&_D1,&_R1,&_P1,mx1calib,my1calib);
        cvInitUndistortRectifyMap(&_M2calib,&_D2,&_R2,&_P2,mx2calib,my2calib);

Swap the last two parameters of stereoCalibrate

In OpenCV >= 3.0, the signature of stereoCalibrate changed, and you need to simply swap the last two parameters, flags and criteria.

Obsolete C version, OpenCV < 3.0

C: double cvStereoCalibrate(const CvMat* object_points, const CvMat* image_points1, const CvMat* image_points2, const CvMat* npoints, CvMat* camera_matrix1, CvMat* dist_coeffs1, CvMat* camera_matrix2, CvMat* dist_coeffs2, CvSize image_size, CvMat* R, CvMat* T, CvMat* E=0, CvMat* F=0, CvTermCriteria term_crit=cvTermCriteria( CV_TERMCRIT_ITER+CV_TERMCRIT_EPS,30,1e-6), int flags=CV_CALIB_FIX_INTRINSIC )

C++ version, OpenCV < 3.0

C++: double stereoCalibrate(InputArrayOfArrays objectPoints, InputArrayOfArrays imagePoints1, InputArrayOfArrays imagePoints2, InputOutputArray cameraMatrix1, InputOutputArray distCoeffs1, InputOutputArray cameraMatrix2, InputOutputArray distCoeffs2, Size imageSize, OutputArray R, OutputArray T, OutputArray E, OutputArray F, TermCriteria criteria=TermCriteria(TermCriteria::COUNT+TermCriteria::EPS, 30, 1e-6), int flags=CALIB_FIX_INTRINSIC )

C++ version, OpenCV >= 3.0

double cv::stereoCalibrate ( InputArrayOfArrays objectPoints, InputArrayOfArrays imagePoints1, InputArrayOfArrays imagePoints2, InputOutputArray cameraMatrix1, InputOutputArray distCoeffs1, InputOutputArray cameraMatrix2, InputOutputArray distCoeffs2, Size imageSize, OutputArray R, OutputArray T, OutputArray E, OutputArray F, int flags = CALIB_FIX_INTRINSIC, TermCriteria criteria = TermCriteria(TermCriteria::COUNT+TermCriteria::EPS, 30, 1e-6) )

Your code is using C api, which is obsolete. You should really consider to use C++ api now.

Yeah it works, but now got other error. I think something wrong with the header. The error is above: — Lina Khoirunisya, Jun 05 '16 at 17:28
error LNK2019: unresolved external symbol "public: void __thiscall CBlobResult::Filter (class CBlobResult &,int,class COperadorBlob *,int,double,double)" (?Filter@CBlobResult@@QAEXAAV1@HPAVCOperadorBlob@@HNN@Z) referenced in function "public: void __thiscall StereoFunctions::stereoDetect(void)" (?stereoDetect@StereoFunctions@@QAEXXZ) — Lina Khoirunisya, Jun 05 '16 at 17:29
This other error has nothing to do with the question... So please ask a new question about that. If my answer solves the problem stated in this question, than please accept the answer. — Miki, Jun 05 '16 at 17:30
