Method Details

getAccuracy

public static double getAccuracy(double expectedDistance,
 AverageMeasurement firstAverageMeasurement,
 AverageMeasurement secondAverageMeasurement)

This method computes the distance of two average points. Then the expected distance is subtracted from the distance of the points.

Parameters:

expectedDistance - - value of type double

firstAverageMeasurement - - value of type AverageMeasurement

secondAverageMeasurement - - value of type AverageMeasurement

Returns:

accurate - the distance

getAccuracyRotation

public static Quaternion getAccuracyRotation(Quaternion expectedRotation,
 Measurement firstMeasurement,
 Measurement secondMeasurement)

This method gets a quaternion (four double values) and two measurements. With the method getRotation the quaternion of firstMeasurement is fetched. From this value, the second quaternion is subtracted from the second measurement. Then the expected quaternion is subtracted.

Parameters:

expectedRotation - - of type quaternion

firstMeasurement - - of type Measurement

secondMeasurement - - of type Measurement

Returns:

result - of type quaternion

getBoxPlot

public static BoxPlot getBoxPlot(List<Double> values)

This method calculates the values for a boxplot. The values are sorted by using the sort method of the Collections class. After that, an array is created from the ArrayList using the method toDoubleArray, because the Percentile class can only count on arrays. The values are calculated using the available methods in these two classes.

Parameters:

values - - a list with values

Returns:

boxPlot - of type boxPlot with results
