Description

The operator best_match_rotbest_match_rotbest_match_rotBestMatchRotBestMatchRot performs a matching of the template of TemplateIDTemplateIDTemplateIDTemplateIDtemplateID and ImageImageImageImageimage. It works similar to best_matchbest_matchbest_matchBestMatchBestMatch with the extension that the pattern can be rotated. 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_rotcreate_template_rotCreateTemplateRotCreateTemplateRot). In addition to best_matchbest_matchbest_matchBestMatchBestMatch best_match_rotbest_match_rotbest_match_rotBestMatchRotBestMatchRot returns the rotion angle of the pattern in AngleAngleAngleAngleangle (radiant). The accuracy of this angle depends on the parameter AngleStep of create_template_rotcreate_template_rotcreate_template_rotCreateTemplateRotCreateTemplateRot. In the case of SubPixelSubPixelSubPixelSubPixelsubPixel = 'true'"true""true""true""true" the position and the angle are calculated with “sub pixel” accuracy.

Result

If the parameter values are correct, the operator best_match_rotbest_match_rotbest_match_rotBestMatchRotBestMatchRot 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>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
