		eVision.EFrameScaling	frameScaling )

Creates an EFrame from the EFoundPattern.

Parameters

useAngle	Whether to use the angle of the EFoundPattern in the frame.
frameScaling	How to handle the scale of the frame.

Creates an EFrame from the EFoundPattern.

Property Documentation

◆ Angle

float eVision.EFoundPattern.Angle

get

Angle of the found instance, in clockwise direction and in the current angle unit.

This returned value is always comprised in the range [- a half turn, + a half turn].

◆ AreaRatio

float eVision.EFoundPattern.AreaRatio

get

When the EFoundPattern was computed from an EMatcher: Ratio between the found pattern area inside the search ROI/Region and its complete area. When the EFoundPattern was computed from an EPatternFinder: returns 1.0.

◆ Center

eVision.EPoint eVision.EFoundPattern.Center

get

Reference point of the instance.

By default, this is its center. If the property EPatternFinder.Pivot has been changed in the EPatternFinder, the point returns the pivot_ in the instance.

◆ DrawBoundingBox

bool eVision.EFoundPattern.DrawBoundingBox

getset

Flag indicating if the EFoundPattern.Draw method must draw the bounding box of the FoundPattern.

The default value is true.

◆ DrawCenter

bool eVision.EFoundPattern.DrawCenter

getset

Flag indicating if the EFoundPattern.Draw method must draw the center of the FoundPattern.

The default value is true.

◆ DrawFeaturePoints

bool eVision.EFoundPattern.DrawFeaturePoints

getset

Flag indicating if the EFoundPattern.Draw method must draw the feature points of the EFoundPattern.EFoundPattern object.

When the EFoundPattern was computed from an EMatcher, there are no feature points to draw and setting this to true will throw an Exception.

When the EFoundPattern was computed from an EPatternFinder in which:

EPatternFinder.ComputePerFeaturePointScore is true, the feature points are drawn in a Red-Yellow-Green colormap, where red indicates a per feature-point score close to -1, yellow to 0 and green to 1.
EPatternFinder.ComputePerFeaturePointScore is false, the feature points are drawn using the default color of the DrawAdapter.

The default value is false.

◆ DrawRegion

eVision.EDrawRegion eVision.EFoundPattern.DrawRegion

getset

Flag indicating if the EFoundPattern.Draw method must draw the region of the EFoundPattern object (region that was used during Learn), its contour or neither. If no region was used during learning, setting this to EDrawRegion.EDrawRegion_DrawContour or EDrawRegion.EDrawRegion_Draw will throw an exception. See EFoundPattern.HasRegion to check if a region was used during learning.

The default value is EDrawRegion.EDrawRegion_NoDraw.

◆ HasFeaturePoints

bool eVision.EFoundPattern.HasFeaturePoints

get

Indicates whether there are feature points within this EFoundPattern. See EFoundPattern.DrawFeaturePoints to draw the feature points.

◆ HasRegion

bool eVision.EFoundPattern.HasRegion

get

Indicates whether there is an ERegion associated with this EFoundPattern, i.e. whether an ERegion was used during the learning of the pattern. See EFoundPattern.DrawRegion to draw the region.

◆ LearntPatternIndex

uint eVision.EFoundPattern.LearntPatternIndex

get

Returns the index of the pattern learnt by EPatternFinder.LearnPatterns or EMatcher.LearnPatterns corresponding to this EFoundPattern.EFoundPattern or 0 if a single pattern was learnt.

◆ Quadrangle

eVision.EQuadrangle eVision.EFoundPattern.Quadrangle

get

Returns the corners of the bounding box of the found pattern.

◆ Scale

float eVision.EFoundPattern.Scale

get

Scaling factor of the found pattern, in units (not percent).

Querying this will throw an Exception if EFoundPattern.ScaleX != EFoundPattern.ScaleY.

◆ ScaleX

float eVision.EFoundPattern.ScaleX

get

Horizontal Scaling factor of the found pattern, in units (not percent).

EPatternFinder does not support anisotropic scaling. In that case, this will return the same result as EFoundPattern.Scale.

◆ ScaleY

float eVision.EFoundPattern.ScaleY

get

Vertical Scaling factor of the found pattern, in units (not percent).

EPatternFinder does not support anisotropic scaling. In that case, this will return the same result as EFoundPattern.Scale.

◆ Score

float eVision.EFoundPattern.Score

get

Matching score of the found pattern, in units (not percent).

The matching score range is [-1.0..1.0].
