threshold is larger than this value can be detected. The larger the value, the stronger noise
resistibility, the smaller the number of edges obtained, and even the target edge points are
filtered out.
Edge Width
It means the edge span. The larger the span, the slower the edge transition speed will be. It is
recommended to set a large value. if the two edges are too close, the large value may result in
edge losing.
Caliper Quantity
It is used to scan ROI area quantity of edge points.
Removed Point
It means that the number of minimum points that have high error to be excluded from fitting. In
general, if there is a great number of points excluded from fitting, its value should be set higher.
For better results, it is recommended to use it in combination with the parameter of distance to
remove.
Removed Distance
The max. pixel distance from the outliers to the fit circle. The smaller the value, the more the
exclusion points.
Projection Width
It means that the area width of edge point ROI. You can increase this parameter value within a
certain range to obtain a more stable edge points.
Initial Fit Type
It has two types, including Global Fit and Local Optimum. Global Fit is used to find global
feature points and fit circle. Local Optimum is used to fit the circle according to the local feature
points.
Fit Mode
It has three types, including Least Squares, huber and tukey. As the number of outliers and the
distance from the group increases, it is recommended to use least squares, huber, and tukey
successively.
