Description

The operator find_planar_calib_deformable_modelfind_planar_calib_deformable_modelFindPlanarCalibDeformableModelFindPlanarCalibDeformableModelFindPlanarCalibDeformableModel finds the best NumMatchesNumMatchesNumMatchesNumMatchesnumMatches instances of the calibrated deformable model ModelIDModelIDModelIDModelIDmodelID in the input image ImageImageImageImageimage. The model must have been created previously by calling create_planar_calib_deformable_modelcreate_planar_calib_deformable_modelCreatePlanarCalibDeformableModelCreatePlanarCalibDeformableModelCreatePlanarCalibDeformableModel or read_deformable_modelread_deformable_modelReadDeformableModelReadDeformableModelReadDeformableModel. The operator find_planar_calib_deformable_modelfind_planar_calib_deformable_modelFindPlanarCalibDeformableModelFindPlanarCalibDeformableModelFindPlanarCalibDeformableModel returns the 3D PosePosePosePosepose of the found instances in the camera coordinate system.

Additionally, the accuracy of the six pose parameters are returned in CovPoseCovPoseCovPoseCovPosecovPose. By default, CovPoseCovPoseCovPoseCovPosecovPose contains the 6 standard deviations of the pose parameters for each match. If the generic parameter 'cov_pose_mode'"cov_pose_mode""cov_pose_mode""cov_pose_mode""cov_pose_mode" was set to 'covariances'"covariances""covariances""covariances""covariances", CovPoseCovPoseCovPoseCovPosecovPose contains the 36 values of the complete 6×6 covariance matrix of the 6 pose parameters. Note that this reflects only an inner accuracy from which the real accuracy of the pose may differ. Finally, the score of each found instance is returned in ScoreScoreScoreScorescore. The score is a number between 0 and 1, which is an approximate measure of how much of the model is visible in the image.
