Constructor & Destructor Documentation

◆ ECircleGauge() [1/2]

eVision.Legacy.ECircleGauge.ECircleGauge ( )

Constructs a circle measurement context.

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

◆ ECircleGauge() [2/2]

eVision.Legacy.ECircleGauge.ECircleGauge ( eVision.Legacy.ECircleGauge other)

Constructs a circle measurement context.

Parameters
otherAnother ECircleGauge object to be copied in the new ECircleGauge object.

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

Member Function Documentation

◆ AddSkipRange() [1/2]

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

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

Parameters
rangeThe 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 ECircleGauge. 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 ECircleGauge.NumSamples).

◆ AddSkipRange() [2/2]

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

Property Documentation

◆ Active

new bool eVision.Legacy.ECircleGauge.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 ECircleGauge.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.ECircleGauge.AverageDistance
get

Average distance between the sampled points and the fitted model.

Irrelevant in case of a point location operation.

◆ Circle

override eVision.Legacy.ECircle eVision.Legacy.ECircleGauge.Circle
set

Sets the nominal position (center coordinates), diameter, angular origin and amplitude of the circle fitting gauge according to a known circle.

◆ FilteringThreshold

float eVision.Legacy.ECircleGauge.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.ECircleGauge.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.

◆ InnerFilteringEnabled

bool eVision.Legacy.ECircleGauge.InnerFilteringEnabled
get

Getter method for the GetInnerFilteringEnabled property. This property is the flag indicating if the inner sampled point filtering is enabled (true), or not.

The inner sampled point filtering is activated as soon as the corresponding ECircleGauge.InnerFilteringThreshold is set. To disable inner filtering, use the ECircleGauge.DisableInnerFiltering method.

◆ InnerFilteringThreshold

float eVision.Legacy.ECircleGauge.InnerFilteringThreshold
getset

Sampled point inner filtering threshold.

If inner filtering is enabled, the sampled points that have been found inside the measured circle are filtered in regard of their distance to it. If this distance is greater than the threshold, the sampled point is set as invalid, and removed from the measure. This distance is in physical units. The inner sampled point filtering is activated as soon as the corresponding threshold is set. To disable inner filtering, use the ECircleGauge.DisableInnerFiltering method.

◆ MeasuredCircle

eVision.Legacy.ECircle eVision.Legacy.ECircleGauge.MeasuredCircle
get

Information pertaining to the fitted circle.

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

◆ MinAmplitude

uint eVision.Legacy.ECircleGauge.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.ECircleGauge.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.ECircleGauge.MinNumFitSamples
getset

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

In case of a ECircleGauge, a single value is used. When the ECircleGauge.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.ECircleGauge.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.ECircleGauge.NumMeasuredPoints
get

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

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

◆ NumSamples

uint eVision.Legacy.ECircleGauge.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.ECircleGauge.NumSkipRanges
get

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

◆ NumValidSamples

uint eVision.Legacy.ECircleGauge.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.ECircleGauge.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.ECircleGauge.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.ECircle eVision.Legacy.ECircleGauge.Shape
get

◆ Smoothing

uint eVision.Legacy.ECircleGauge.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.ECircleGauge.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.ECircleGauge.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.ECircleGauge.Tolerance
getset

Searching area half thickness of the circle fitting gauge.

A circle fitting gauge is fully defined knowing its nominal position (given by the coordinates of its center), its nominal radius (diameter), the angular position from where it extents, its angular amplitude and its outline tolerance. By default, the searching area thickness of the circle 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.ECircleGauge.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 ECircleGauge.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.ECircleGauge.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.ECircleGauge.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.ECircleGauge.Type
get

Shape type.

◆ Valid

bool eVision.Legacy.ECircleGauge.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 ECircleGauge.MeasureSample, and thus a point has been measured.
