keine geeignete Konvertierungsfunktion von "CvTermCriteria" zu "int" existiert

Question

Wie konnte ich den Fehler beheben?

Ich benutze Programm, das für OpenCV 2.x gemacht, aber ich kompiliere es auf OpenCV 3.0, und Fehler erschien. Ich ändere CvTermCriteria zu TermCriteria :: TermCriteria, aber das funktioniert nicht. Wie kann ich CvTermCriteria ändern, um int zu sein?

Hoffe jemand könnte mir helfen. Dank

Fehler bei diesem Teil erschienen:

tauschen die beiden letzten Parameter von stereoCalibrate

---

In OpenCV> = 3,0 , die Signatur von stereoCalibrate geändert, und müssen Sie sim Vertauschen Sie die letzten beiden Parameter, flags und criteria.

Veraltet C-Version, OpenCV < 3,0

C: Doppel cvStereoCalibrate (const CvMat * object_points, const CvMat * image_points1, const CvMat * image_points2, Konst CvMat * npoints, CvMat * camera_matrix1, CvMat * dist_coeffs1, CvMat * Kamera_Matrix2, CvMat * dist_coeffs2, CvSize Bildgröße, 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++: Doppel stereoCalibrate (InputArrayOfArrays objectPoints, InputArrayOfArrays imagePoints1, InputArrayOfArrays imagePoints2, InputOutputArray cameraMatrix1, InputOutputArray distCoeffs1, InputOutputArray cameraMatrix2, InputOutputArray distCoeffs2, Größe image, Output R, Output T, Output E, Output F, TermCriteria Kriterien = TermCriteria (TermCriteria :: COUNT + TermCriteria :: EPS, 30, 1e-6), int Flags = CALIB_FIX_INTRINSIC)

C++ Version, OpenCV> = 3.0

Doppel cv :: stereoCalibrate (InputArrayOfArrays objectPoints, InputArrayOfArrays imagePoints1, InputArrayOfArrays imagePoints2, InputOutputArray cameraMatrix1, InputOutputArray distCoeffs1, InputOutputArray cameraMatrix2, InputOutputArray distCoeffs2, Größe image, Output R, Output T , AusgabeArray E, AusgabeArray F, int Kennzeichen = CALIB_FIX_INTRINSIC, TermCriteria Kriterien = TermCriteria (TermCriteria :: COUNT + TermCriter ia :: EPS, 30, 1e-6) )

Ihr Code wird unter Verwendung von C api, die obsolet ist. Sie sollten jetzt wirklich überlegen, C++ API zu verwenden.
