//保存成xml

cvSave("intrinsic_left.xml", &intrinsic_left);

cvSave("intrinsic_right.xml", &intrinsic_right);

cvSave("distortion_left.xml", &distortion_left);

cvSave("distortion_right.xml", &distortion_right);

cvSave("R.xml", &R);

cvSave("T.xml", &T);

//cvload的xml

CvMat *_M1 = (CvMat*)cvLoad("intrinsic_left.xml");

CvMat *_M2 = (CvMat*)cvLoad("intrinsic_right.xml");

CvMat *_D1 = (CvMat*)cvLoad("distortion_left.xml");

CvMat *_D2 = (CvMat*)cvLoad("distortion_right.xml");

CvMat *_R= (CvMat*)cvLoad("R.xml");

//CvMat *_r = (CvMat*)cvLoad("R.xml");

//CvMat *_R = cvCreateMat(3, 3, CV_64F);

CvMat *_T = (CvMat*)cvLoad("T.xml");

// 旋转矩阵罗德里格斯变换

//cvRodrigues2(_r, _R, NULL);

cout<<"ok!!";

return 0;

}

运行成功后，可在运行文件中找到这几个xml，如果要将R矩阵由3*1转换成3*3使用则需使用罗德里格斯变换
