CogLineMax.EdgeAngleTolerance Property

CogLineMax EdgeAngleTolerance Property

Cognex VisionPro 9.20

Gets or sets the maximum allowable angle between a line and an inlier of the line. Edge points must meet this constraint to become inliers of the line.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	Thrown when you assign a value less than zero or greater than PI/2.

Remarks

In case of better image quality and cleaner edges, a smaller EdgeAngleTolerance helps increase the robustness of line finding. In case of noisier edges, edge points on the desired line may have noisy gradient directions, therefore a larger EdgeAngleTolerance is advised.
