void | cv::detail::estimateFocal (const std::vector< ImageFeatures > &features, const std::vector< MatchesInfo > &pairwise_matches, std::vector< double > &focals) |
Estimates focal lengths for each given camera. More... | |
void | cv::detail::focalsFromHomography (const Mat &H, double &f0, double &f1, bool &f0_ok, bool &f1_ok) |
Tries to estimate focal lengths from the given homography under the assumption that the camera undergoes rotations around its centre only. More... | |
void cv::detail::estimateFocal | ( | const std::vector< ImageFeatures > & | features, |
const std::vector< MatchesInfo > & | pairwise_matches, | ||
std::vector< double > & | focals | ||
) |
Estimates focal lengths for each given camera.
features | Features of images. |
pairwise_matches | Matches between all image pairs. |
focals | Estimated focal lengths for each camera. |
void cv::detail::focalsFromHomography | ( | const Mat & | H, |
double & | f0, | ||
double & | f1, | ||
bool & | f0_ok, | ||
bool & | f1_ok | ||
) |
Tries to estimate focal lengths from the given homography under the assumption that the camera undergoes rotations around its centre only.
H | Homography. |
f0 | Estimated focal length along X axis. |
f1 | Estimated focal length along Y axis. |
f0_ok | True, if f0 was estimated successfully, false otherwise. |
f1_ok | True, if f1 was estimated successfully, false otherwise. |
