示例1:

/**
 * Find 3D rotation and translation with homography (i.e. calibration boards position in the camera cooperate system )
 * @param homo: [Input] Estimated Homography
 * @param rot: [Output] Rotation result
 * @param trans: [Output] Translation result
 */
void AugmentationEnvironment::H2Rt(const cv::Mat_<double> intrisinc, const cv::Mat_<double>& homo, cv::Mat_<double>& rot, cv::Mat_<double> &trans)
{
	double coefH;

	cv::Mat_<double> invcam = intrisinc.inv();
	rot = invcam*homo;

	//scaling rotation matrix to right order = find the coefficient lost while calculating homography
	/**
	 * [Cam]*[Rot]' = [Homo]*coefH
	 *          |fx  0  u0|
	 * [Cam]' = | 0 fy  v0|
	 *          | 0  0   1|
	 *
	 *          |R11 R12 t1|
	 * [Rot]' = |R21 R22 t2|
	 *          |R31 R32 t3|
	 *
	 *           |H11 H12 H13|
	 * [Homo]' = |H21 H22 H23|
	 *           |H31 H32   1|
	 */
	coefH = 2/(cv::norm(rot.col(0)) + cv::norm(rot.col(1)));
	rot = rot * coefH;
	trans = rot.col(2).clone();

	//The their rotation vector in the rotation matrix is produced as the cross product of other two vectors
	cv::Mat tmp = rot.col(2);
	rot.col(0).cross(rot.col(1)).copyTo(tmp);

	//Add here to make rotation matrix a "real" rotation matrix in zhang's method
	/**
	 * rot = UDVt
	 * rot_real = UVt
	 */
	cv::Mat_<double> D,U,Vt;
	cv::SVD::compute(rot,D,U,Vt);
	rot = U*Vt;
