Constructor & Destructor Documentation

◆ ELineGauge() [1/2]

eVision.Legacy.ELineGauge.ELineGauge ( )

Constructs a line measurement context.

With the default constructor, all the parameters are initialized to their respective default values. With the copy constructor, the constructed line measurement context is based on a pre-existing ELineGauge.ELineGauge object. The gauge children are also copied. Hierarchy copying through a copy constructor is always recursive. To disable this recursion, use instead the ELineGauge.CopyTo method.

◆ ELineGauge() [2/2]

eVision.Legacy.ELineGauge.ELineGauge ( eVision.Legacy.ELineGauge other )

Constructs a line measurement context.

Parameters

other Another ELineGauge object to be copied in the new ELineGauge object.

With the default constructor, all the parameters are initialized to their respective default values. With the copy constructor, the constructed line measurement context is based on a pre-existing ELineGauge.ELineGauge object. The gauge children are also copied. Hierarchy copying through a copy constructor is always recursive. To disable this recursion, use instead the ELineGauge.CopyTo method.

Member Function Documentation

◆ AddSkipRange() [1/2]

uint eVision.Legacy.ELineGauge.AddSkipRange ( eVision.EIntegerRange range )

Adds an item to the set of skip ranges and returns the index of the newly added range.

Parameters

range The skip range.

The samples indices between start and end (including the boundaries) will be discarded during the measurement process. This method allows to define skip ranges in an ELineGauge. This means that, at measure time, samples belonging to these ranges will not be taken into account. A sample may belong to more than one skip range; to be discarded, a sample has to pertain to at least one range. Moreover, the skip ranges are allowed to overlap one another. The range is allowed to be reversed (i.e. end is not required to be greater than start). Also, start and end are not required to reference valid indices at the time of the call (i.e. the range may lie outside of the current return value for ELineGauge.NumSamples).

◆ AddSkipRange() [2/2]

uint eVision.Legacy.ELineGauge.AddSkipRange	(	uint	start,
		uint	end )

Adds an item to the set of skip ranges and returns the index of the newly added range.

Parameters

start	Beginning of the skip range.
end	End of the skip range.

The samples indices between start and end (including the boundaries) will be discarded during the measurement process. This method allows to define skip ranges in an ELineGauge. This means that, at measure time, samples belonging to these ranges will not be taken into account. A sample may belong to more than one skip range; to be discarded, a sample has to pertain to at least one range. Moreover, the skip ranges are allowed to overlap one another. The range is allowed to be reversed (i.e. end is not required to be greater than start). Also, start and end are not required to reference valid indices at the time of the call (i.e. the range may lie outside of the current return value for ELineGauge.NumSamples).

Property Documentation

◆ Active

new bool eVision.Legacy.ELineGauge.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 ELineGauge.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).

◆ AverageDistance

float eVision.Legacy.ELineGauge.AverageDistance

get

Average distance between the sampled points and the fitted model.

Irrelevant in case of a point location operation.

◆ ClippingMode

eVision.EClippingMode eVision.Legacy.ELineGauge.ClippingMode

getset

Clipping mode, that allows to choose how the fitted segment length and center are computed.

By default, the clipping mode is EClippingMode.EClippingMode_CenteredNominal, which corresponds to the behavior appearing in eVision version 6.4 and before.

◆ FilteringThreshold

float eVision.Legacy.ELineGauge.FilteringThreshold

getset

Relative filtering threshold, that is the fraction of the average distance between the sampled points and the fitted model above which a point is filtered out.

Irrelevant in case of a point location operation. During a model fitting operation, the "filtering" process can be invoked to remove outliers, i.e. points that were located significantly far away from the fitted model (so that their position is dubious).

◆ HVConstraint

bool eVision.Legacy.ELineGauge.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.

◆ KnownAngle

bool eVision.Legacy.ELineGauge.KnownAngle

getset

Flag indicating whether the slope of the line to be fitted is known or not.

A line model to be fitted may have a well-known slope. It is possible to impose the value of this slope, thus removing one degree of freedom. The line fitting gauge slope is set by means of ELineShape.Angle. 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.

◆ Line

override eVision.Legacy.ELine eVision.Legacy.ELineGauge.Line

set

Sets the nominal position, length and rotation angle of the line fitting gauge, according to a known ELine object.

◆ MeasuredLine

eVision.Legacy.ELine eVision.Legacy.ELineGauge.MeasuredLine

get

Information pertaining to the fitted line.

Use method EShape.GetFound to get the status of the measurement. ELineGauge.MeasuredLine returns a successful fitted line if EShape.GetFound is true, otherwise it returns the orginal (nominal) line.

◆ MinAmplitude

uint eVision.Legacy.ELineGauge.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.ELineGauge.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.

◆ MinNumFitSamples

int eVision.Legacy.ELineGauge.MinNumFitSamples

getset

Sets/Gets the minimum number of samples required for fitting the shape.

In case of a ELineGauge, a single value is returned. When the ELineGauge.Measure method is called, and if not enough valid points are detected, then the method returns directly, and the measured gauge is set to the nominal parameters.

◆ NumFilteringPasses

uint eVision.Legacy.ELineGauge.NumFilteringPasses

getset

Number of filtering passes for a model fitting operation.

Irrelevant in case of a point location operation. During a filtering pass, the points that are too distant from the model are discarded. During a model fitting operation, the "filtering" process can be invoked to remove outliers, i.e. points that were located significantly far away from the fitted model (so that their position is dubious). By default (the number of filtering passes is 0), the outliers rejection process is disabled.

◆ NumMeasuredPoints

uint eVision.Legacy.ELineGauge.NumMeasuredPoints

get

Number of edge-crossing points along the sample path of the gauge that was inspected with the last call to ELineGauge.MeasureSample.

Note: For this method to succeed, it is necessary to previously call ELineGauge.MeasureSample.

◆ NumSamples

uint eVision.Legacy.ELineGauge.NumSamples

get

Number of sampled points during the model fitting operation.

Irrelevant in case of a point location operation. After a model fitting operation, a number of points have been fitted along the model. Among them, some are not reliable because of their Area value. Among the remaining ones, some are filtered out (NumFilteringPasses, FilteringThreshold).

◆ NumSkipRanges

uint eVision.Legacy.ELineGauge.NumSkipRanges

get

Number of skip ranges in the gauge after a call to ELineGauge.AddSkipRange.

◆ NumValidSamples

uint eVision.Legacy.ELineGauge.NumValidSamples

get

Number of valid sample points remaining after a model fitting operation.

Irrelevant in case of a point location operation. After a model fitting operation, a number of points have been fitted along the model. Among them, some are not reliable because of their Area value. Among the remaining ones, some are filtered out (NumFilteringPasses, FilteringThreshold).

◆ RectangularSamplingArea

bool eVision.Legacy.ELineGauge.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.

◆ SamplingStep

float eVision.Legacy.ELineGauge.SamplingStep

getset

Approximate distance between sampled points during a model fitting operation.

Irrelevant in case of a point location operation. To fit a model, a series of point location operations are performed along the model. The point location gauges spacing is given by the sampling step. By default, the sampling step is set to 5, which means 5 pixels when the field of view is not calibrated, and 5 physical units in case of a calibrated field of view. Be aware that if the sampling step is too large, the number of sampled points along the model will not be sufficient enough to accurately locate it.

◆ Shape

eVision.Legacy.ELine eVision.Legacy.ELineGauge.Shape

get

◆ Smoothing

uint eVision.Legacy.ELineGauge.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.ELineGauge.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.ELineGauge.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.ELineGauge.Tolerance

getset

Searching area half thickness of the line fitting gauge.

By default, the searching area thickness of the line fitting 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.

◆ TransitionChoice

eVision.ETransitionChoice eVision.Legacy.ELineGauge.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 ELineGauge.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.ELineGauge.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.ELineGauge.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.ELineGauge.Type

get

Shape type.

◆ Valid

bool eVision.Legacy.ELineGauge.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 inspected with the last call to ELineGauge.MeasureSample, and thus a point has been measured.
