Description

The operator best_match_rot_mgbest_match_rot_mgBestMatchRotMgBestMatchRotMgBestMatchRotMg performs a matching of the template of TemplateIDTemplateIDTemplateIDTemplateIDtemplateID and ImageImageImageImageimage. It works similar to best_match_mgbest_match_mgBestMatchMgBestMatchMgBestMatchMg with the extension that the pattern can be rotated analogously to best_match_rotbest_match_rotBestMatchRotBestMatchRotBestMatchRot. The parameters AngleStartAngleStartAngleStartAngleStartangleStart and AngleExtendAngleExtendAngleExtendAngleExtendangleExtend define the maximum rotation of the pattern: AngleStartAngleStartAngleStartAngleStartangleStart specifies the maximum counter clockwise rotation and AngleExtendAngleExtendAngleExtendAngleExtendangleExtend the maximum clockwise rotation relative to this angle. Both values have to smaller or equal to the values used for the creation of the pattern (see create_template_rotcreate_template_rotCreateTemplateRotCreateTemplateRotCreateTemplateRot). In addition to best_match_mgbest_match_mgBestMatchMgBestMatchMgBestMatchMg best_match_rot_mgbest_match_rot_mgBestMatchRotMgBestMatchRotMgBestMatchRotMg returns the rotation angle of the pattern in AngleAngleAngleAngleangle (radiant).

The value of MaxErrorMaxErrorMaxErrorMaxErrormaxError must be set larger in comparison with the operator best_match_rotbest_match_rotBestMatchRotBestMatchRotBestMatchRot, because often the error is larger at higher levels of the pyramid.

In the case of SubPixelSubPixelSubPixelSubPixelsubPixel = 'true'"true""true""true""true" the position and the angle are calculated with “sub pixel” accuracy.

The value of NumLevelsNumLevelsNumLevelsNumLevelsnumLevels has to equal or smaller than the value used to create the template.

Result

If the parameter values are correct, the operator best_match_rot_mgbest_match_rot_mgBestMatchRotMgBestMatchRotMgBestMatchRotMg returns the value 2 (H_MSG_TRUE). If the input is empty (no input images are available) the behaviour can be set via set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
