Field Details

position

private P extends com.irurueta.geometry.Point<?> position

Position where fingerprint readings were made.

positionCovariance

private com.irurueta.algebra.Matrix positionCovariance

Constructor Details

RssiFingerprintLocated

protected RssiFingerprintLocated(List<R> readings,
 P position)

Constructor.

Parameters:

readings - non-located RSSI readings defining the fingerprint.

position - position where readings were made.

Throws:

IllegalArgumentException - if either readings or position are null.

RssiFingerprintLocated

protected RssiFingerprintLocated(List<R> readings,
 P position,
 com.irurueta.algebra.Matrix positionCovariance)

Constructor.

Parameters:

readings - non-located RSSI readings defining the fingerprint.

position - position where readings were made.

positionCovariance - covariance of inhomogeneous coordinates of current position (if available).

Throws:

IllegalArgumentException - if either readings or position are null, or covariance has invalid size.

RssiFingerprintLocated

protected RssiFingerprintLocated()

Empty constructor.
