Description

The operator best_match_rot_mgbest_match_rot_mgBestMatchRotMgbest_match_rot_mgBestMatchRotMgBestMatchRotMg performs a matching of the template of TemplateIDTemplateIDTemplateIDTemplateIDTemplateIDtemplateID and ImageImageImageImageImageimage. It works similar to best_match_mgbest_match_mgBestMatchMgbest_match_mgBestMatchMgBestMatchMg with the extension that the pattern can be rotated analogously to best_match_rotbest_match_rotBestMatchRotbest_match_rotBestMatchRotBestMatchRot. The parameters AngleStartAngleStartAngleStartAngleStartAngleStartangleStart and AngleExtendAngleExtendAngleExtendAngleExtendAngleExtendangleExtend define the maximum rotation of the pattern: AngleStartAngleStartAngleStartAngleStartAngleStartangleStart specifies the maximum counter clockwise rotation and AngleExtendAngleExtendAngleExtendAngleExtendAngleExtendangleExtend 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_rotCreateTemplateRotcreate_template_rotCreateTemplateRotCreateTemplateRot). In addition to best_match_mgbest_match_mgBestMatchMgbest_match_mgBestMatchMgBestMatchMg best_match_rot_mgbest_match_rot_mgBestMatchRotMgbest_match_rot_mgBestMatchRotMgBestMatchRotMg returns the rotion angle of the pattern in AngleAngleAngleAngleAngleangle (radiant).

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

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

The value of NumLevelsNumLevelsNumLevelsNumLevelsNumLevelsnumLevels 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_mgBestMatchRotMgbest_match_rot_mgBestMatchRotMgBestMatchRotMg 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>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
