圆模型在第一次教学过程中总是返回 2 个模型（一个圆轮廓和一个中心点）。这是必要的，因为圆轮廓总是返回一个精确的圆和相应的中心点。
信息：
中心点模型不能脱离相关的圆边模型单独移动。
用于圆搜索的轮廓线只是与找到的实际圆轮廓线相匹配的边缘；下图中用红色标出，以示说明。绿色圆线是根据找到的边缘确定的圆，用于测量。
模型参数 "完整度 "指的是要搜索的边缘，在图片中用红色标出。完整度 "值小于 100%，例如，如果边缘模糊、部分被覆盖或以其他方式中断，则可使用该值。
信息：
在循环模型的示教过程中，模型参数 "完整性 "的返回值始终为 1.0，只能在示教后更改。
如果更改了其他模型参数，也会触发示教！
The circle model always returns 2 models (one circle contour and one center point) in the first teach-in process. This is necessary because a circle contour always returns an exact circle with the corresponding center point.
Information:
A center point model cannot be moved independently of the associated circle edge model.
The contour used for a circle search is only the edge that matches the actual circle contour found; this is marked in red for illustration in the image below. The green circle line is the circle determined with the found edge and is used for the measurement.
Model parameter "Completeness" refers to the edge to be searched for and marked red in the image. A "Completeness" value less than 100% can be used, for example, if edges are blurred, partially covered or otherwise interrupted.
Information:
Model parameter Completeness is always returned with value 1.0 during teach-in of a circular model and can only be changed afterwards.
If other model parameters are changed, this can also trigger a teach-in!
