◆ SetTolerances() [1/2]

void eVision.Legacy.EPointGauge.SetTolerances ( float tolerance )

Sets the half length and the rotation angle of the point location gauge.

Parameters

tolerance Half length of the point location gauge. The default value is 10.

By default, the point location gauge length value is 20 (2x10), which means 20 pixels when the field of view is not calibrated and 20 "units" in case of a calibrated field of view. The sign of the rotation angle depends whether the field of view is calibrated or not.

When the field of view is calibrated, the coordinate system is said to be direct, the abscissa extends rightwards and the ordinate extends upwards. In this case, an anticlockwise rotation leads to a positive angle value.
When the field of view is not calibrated, the coordinate system is said to be inverse, the abscissa extends rightwards and the ordinate extends downwards. In this case, a clockwise rotation leads to a positive angle value.

Sets the half length and the rotation angle of the point location gauge.

Parameters

tolerance	Half length of the point location gauge. The default value is 10.
angle	Rotation angle of the point location gauge. The default value is 0.

By default, the point location gauge length value is 20 (2x10), which means 20 pixels when the field of view is not calibrated and 20 "units" in case of a calibrated field of view. The sign of the rotation angle depends whether the field of view is calibrated or not.

When the field of view is calibrated, the coordinate system is said to be direct, the abscissa extends rightwards and the ordinate extends upwards. In this case, an anticlockwise rotation leads to a positive angle value.

Property Documentation

◆ Active

new bool eVision.Legacy.EPointGauge.Active

getset

Sets the flag indicating whether the gauge is active or not.

When complex gauging is required, several gauges can be grouped together. Applying EPointGauge.Process to the mother gauge or shape triggers the measurement of the whole. Only the active gauges will participate in the process. By default, the gauge is active (true).

◆ Center

override eVision.EPoint eVision.Legacy.EPointGauge.Center

set

Center coordinates of a EPointGauge object.

◆ HVConstraint

bool eVision.Legacy.EPointGauge.HVConstraint

getset

Status of the restriction on the orientation of the point location gauge or model fitting sample paths.

Sample paths are the point location gauges placed along the model to be fitted.

◆ MeasuredPeaks

eVision.EPeak [] eVision.Legacy.EPointGauge.MeasuredPeaks

get

Returns information pertaining to the derivative peak associated with all of the edge-crossing point, such as its area, amplitude, start, length and center.

If you want to query less than 10 peaks, using EPointGauge.GetMeasuredPeak should be faster.

Note: For this method to succeed, it is necessary to previously call EPointGauge.Measure.

◆ MeasuredPoints

eVision.EPoint [] eVision.Legacy.EPointGauge.MeasuredPoints

get

Returns the coordinates of all edge-crossing points, measured along the unique sample path of the point location gauge.

These coordinates pertain to the World space; they are expressed in the reference frame to which the current EPointGauge object belongs.

If you want to query less than 10 points, using EPointGauge.GetMeasuredPoint should be faster.

Note: For this method to succeed, it is necessary to previously call EPointGauge.Measure.

◆ MinAmplitude

uint eVision.Legacy.EPointGauge.MinAmplitude

getset

Offset added to the Threshold when a peak is to be detected.

When analyzing a derivative profile, a peak is made up of consecutive pixel values above Threshold. To detect weak [strong] transitions, lower [raise] the Threshold value. To avoid interference of noise, an additional parameter is provided. The MinAmplitude parameter is an offset added to Threshold when a peak is to be detected. When the pixel values of the derivative profile do not reach Threshold + MinAmplitude, the peak is not taken into account. Anyway, when a peak is taken into account, all the pixels with values above Threshold are considered (for more accuracy). Setting the MinAmplitude value to 0 merely cancels its effect.

◆ MinArea

uint eVision.Legacy.EPointGauge.MinArea

getset

Minimum area value.

A transition is detected if its derivative peak reaches Threshold + MinAmplitude value, and then declared valid if the area between the peak curve and the horizontal at level Threshold reaches the MinArea value.

◆ NumMeasuredPoints

uint eVision.Legacy.EPointGauge.NumMeasuredPoints

get

Number of edge-crossing points along the point location gauge.

◆ RectangularSamplingArea

bool eVision.Legacy.EPointGauge.RectangularSamplingArea

getset

Flag indicating whether the sampling area remains a rectangle when rotated, instead of becoming a parallelogram.

By default, this flag is set to true: the sampling area always remains a rectangle. Setting this property is only useful when the thickness transition parameter is greater than 1. In fact, when thickness transition parameter is equal to 1, rectangle and parallelogram reduce to the same segment.

◆ Shape

eVision.EPoint eVision.Legacy.EPointGauge.Shape

get

◆ Smoothing

uint eVision.Legacy.EPointGauge.Smoothing

getset

Number of pixels used for the low-pass filtering operation.

To reduce the effect of noise, the profile data can be low-pass filtered along the point location gauge direction.

◆ Thickness

uint eVision.Legacy.EPointGauge.Thickness

getset

Number of parallel segments used to extract the data profile.

To reduce the effect of noise and/or strengthen a transition, several parallel profiles can be accumulated.

◆ Threshold

uint eVision.Legacy.EPointGauge.Threshold

getset

Threshold level used to delimit significant peaks in the data profile.

When analyzing a derivative profile, a peak is made up of consecutive pixel values above Threshold. To detect weak [strong] transitions, lower [raise] the Threshold value. To avoid interference of noise, an additional parameter is provided. The MinAmplitude parameter is an offset added to Threshold when a peak is to be detected. When the pixel values of the derivative profile do not reach Threshold + MinAmplitude, the peak is not taken into account. Anyway, when a peak is taken into account, all the pixels with values above Threshold are considered (for more accuracy). Setting the MinAmplitude value to 0 merely cancels its effect.

◆ Tolerance

float eVision.Legacy.EPointGauge.Tolerance

getset

Half length of the point location gauge.

By default, the length of the point location gauge is 20 (2x10), which means 20 pixels when the field of view is not calibrated, and 20 physical units in case of a calibrated field of view.

◆ ToleranceAngle

float eVision.Legacy.EPointGauge.ToleranceAngle

getset

Rotation angle of the point location gauge.

By default, the rotation angle of the point location gauge is 0. The sign of the rotation angle depends whether the field of view is calibrated or not.

When the field of view is calibrated, the coordinate system is said to be direct, the abscissa extends rightwards and the ordinate extends upwards. In this case, an anticlockwise rotation leads to a positive angle value.
When the field of view is not calibrated, the coordinate system is said to be inverse, the abscissa extends rightwards and the ordinate extends downwards. In this case, a clockwise rotation leads to a positive angle value.

◆ TransitionChoice

eVision.ETransitionChoice eVision.Legacy.EPointGauge.TransitionChoice

getset

Transition choice.

Several peaks may be detected along a point location gauge. This parameter helps to select the desired transition. In case of ETransitionChoice.ETransitionChoice_NthFromBegin or ETransitionChoice.ETransitionChoice_NthFromEnd transition choice, set EPointGauge.TransitionIndex to specify the desired transition. By default, the selected transition corresponds to the one with the largest amplitude (ETransitionChoice.ETransitionChoice_LargestAmplitude).

◆ TransitionIndex

uint eVision.Legacy.EPointGauge.TransitionIndex

getset

Index (from 0 on) of the transition to be retained when the transition choice parameter is set to ETransitionChoice.ETransitionChoice_NthFromBegin or ETransitionChoice.ETransitionChoice_NthFromEnd.

Several peaks may be detected along a point location gauge. This parameter helps to select the desired transition. By default, the first transition is retained (the index value is 0).

◆ TransitionType

eVision.ETransitionType eVision.Legacy.EPointGauge.TransitionType

getset

Transition type.

The type of a transition tells whether it crosses increasing or decreasing gray-level values. This helps discriminate between nearby edges of an object. By default, the searched transition type is indifferently a black to white or a white to black transition (ETransitionType.ETransitionType_BwOrWb).

◆ Type

override eVision.EShapeType eVision.Legacy.EPointGauge.Type

get

Shape type.

◆ Valid

bool eVision.Legacy.EPointGauge.Valid

get

Flag indicating if at least one valid transition has been found.

A false value means that no measurement has been performed. A true value means that a transition was found along the sample path defined by the EPointGauge, and thus a point was measured.
