没有合适的从"CvTermCriteria"到"int"的转换函数

Question

如何解决错误？

我使用了为OpenCV2.x制作的程序，但我在OpenCV3.0上编译了它，出现了错误。我将CvTermCriteria更改为TermCriteria:：TermCriterias，但这不起作用。如何将CvTermCriteria更改为int？

希望有人能帮我。谢谢

此部分出现错误：

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 );

这是源代码：

//--------------Compute for calibration-------------------
N = n_boards*n;
objectPoints.resize(N);
for( i = 0; i < ny; i++ )

for( i = 1; i < n_boards; i++ ) copy( objectPoints.begin(), objectPoints.begin() + n, objectPoints.begin() + i*n );
npoints.resize(n_boards,n);

交换stereoCalibrate的最后两个参数

---

在OpenCV>=3.0中，stereoCalibrate的签名发生了更改，并且您需要简单地交换最后两个参数，flags和criteria。

过时的C版本，OpenCV<3.0

C： 双cvStereoCalibrate)，int标志=CV_CALIB_FIX_INCINIC)

C++版本，OpenCV<3.0

C++：双立体校准(InputArrayOfArrays objectPoints，InputArrayOfArrays imagePoints1，InputArrayOfArrays imagePoints2，InputOutputArray camera Matrix1，InputOutput Array distCoeffs1，InputOutoutputArray cameraMatrix2，InputOutputArray distCoffs2，Size imageSize，OutputArray R，OutputArray T，OutputArray E，Outputrray F，TermCriteria criteria=TermCriteria(TermCriteria:：COUNT+TermCriteria：：EPS，30，1e-6)，int flags=CALIB_FIX_INTRINSIC)

C++版本，OpenCV>=3.0

double cv:：stereoCalibrate(InputArrayOfArrays对象点，InputArrayOfArrays imagePoints1，InputArrayOfArrays imagePoints2，InputOutputArray cameraMatrix1，InputOutputArray distCoeffs1，InputOutputArray cameraMatrix2，InputOutputArray distCoeffs2，大小图像大小，输出阵列R，OutputArray T，输出阵列E，输出阵列F，int标志＝CALIB_FIX_INTRINSIC，TermCriteria标准=TermCriteria(TermCriteria:：COUNT+TermCriteria:EPS，30，1e-6))

您的代码使用的是C api，这是过时的。您现在真的应该考虑使用C++api了。
