描述
The operator best_match_rotbest_match_rotBestMatchRotBestMatchRotBestMatchRotbest_match_rot performs a matching of the template
of TemplateIDTemplateIDTemplateIDTemplateIDtemplateIDtemplate_id and ImageImageImageImageimageimage.
It works similar to best_matchbest_matchBestMatchBestMatchBestMatchbest_match with the extension
that the pattern can be rotated.
The parameters AngleStartAngleStartAngleStartAngleStartangleStartangle_start and AngleExtendAngleExtendAngleExtendAngleExtendangleExtendangle_extend
define the maximum rotation of the pattern: AngleStartAngleStartAngleStartAngleStartangleStartangle_start
specifies the maximum counter clockwise rotation and
AngleExtendAngleExtendAngleExtendAngleExtendangleExtendangle_extend 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_rotCreateTemplateRotCreateTemplateRotCreateTemplateRotcreate_template_rot).
In addition to best_matchbest_matchBestMatchBestMatchBestMatchbest_match best_match_rotbest_match_rotBestMatchRotBestMatchRotBestMatchRotbest_match_rot
returns the rotation angle of the pattern in AngleAngleAngleAngleangleangle (radiant).
The accuracy of this angle depends on the parameter AngleStep
of create_template_rotcreate_template_rotCreateTemplateRotCreateTemplateRotCreateTemplateRotcreate_template_rot.
In the case of SubPixelSubPixelSubPixelSubPixelsubPixelsub_pixel = 'true'"true""true""true""true""true" the position
and the angle are calculated with “sub pixel” accuracy.
执行信息
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.

结果
If the parameter values are correct, the operator best_match_rotbest_match_rotBestMatchRotBestMatchRotBestMatchRotbest_match_rot
returns the value 2 (
H_MSG_TRUE)
.
If the input is empty (no input images are available) the behavior 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>)set_system("no_object_result",<Result>).
If necessary, an exception is raised.
