描述

算子 create_template_rotcreate_template_rotCreateTemplateRotCreateTemplateRotCreateTemplateRotcreate_template_rot preprocesses a pattern, which is passed as an image, for the template matching. An extension to create_templatecreate_templateCreateTemplateCreateTemplateCreateTemplatecreate_template the matching can applied to rotated patterns. 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. Therefore AngleExtendAngleExtendAngleExtendAngleExtendangleExtendangle_extend has to be smaller than . With the parameter AngleStepAngleStepAngleStepAngleStepangleStepangle_step the maximum angle resolution (on the highest resolution level) can be specified.

You have to be aware, that all possible rotations are calculated beforehand to reduce runtime during matching. This leads to a higher execution time for create_template_rotcreate_template_rotCreateTemplateRotCreateTemplateRotCreateTemplateRotcreate_template_rot and high memory requirements for the template. The amount of memory depends on the parameters AngleExtendAngleExtendAngleExtendAngleExtendangleExtendangle_extend and AngleStepAngleStepAngleStepAngleStepangleStepangle_step. The number of pyramid levels can be neglected. If A is the number of pixels of TemplateTemplateTemplateTemplatetemplatetemplate, the memory M needed for the template in byte is about:

After the transformation, a number (TemplateIDTemplateIDTemplateIDTemplateIDtemplateIDtemplate_id) is assigned to the template for being used in the further process.

A description of the other parameters can be found at the operator create_templatecreate_templateCreateTemplateCreateTemplateCreateTemplatecreate_template。

注意

You have to be aware, that depending on the resolution a large number of pre calculated patterns have to be created which might result in a large amount of memory needed.

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。

此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。
