Cog3DPartCorresponderUsingCrsp2D3DsResult Coverage Property Cognex VisionPro
Gets the coverage of this result.

Namespace: Cognex.VisionPro3D
Assembly: Cognex.VisionPro3D (in Cognex.VisionPro3D.dll) Version: 65.1.0.0
Syntax

public double Coverage { get; }

Property Value

Type: Double
The coverage of this result.
Remarks

The coverage is computed as follows:

Coverage = (number of 2D points) / ((number of 3D model points) * (number of cameras))

Where the number of 3D model points includes the number of distinct 3D model points in the specified crsp2D3Ds (which is the input argument for Cog3DPartCorresponderUsingCrsp2D3Ds.CorrespondPartsUsingPointsAndIntersectionPoints) and the number of the derived 3D points from intersected 3D lines or 3D line segments in the model.

The number of 2D points is the total number of 2D points corresponding to 3D model points for this part instance in the specified crsp2D3Ds, plus the total number of the derived 2D points corresponding to the derived 3D points for this part instance.

Note that Coverage can be used to check whether multiple cameras can see the same part instance or not. Coverage of 1.0 means all cameras can see this part instance.
