navlie.types.Measurement¶

class navlie.types.Measurement(value: ndarray, stamp: float | None = None, model: MeasurementModel | None = None, state_id: Any | None = None)¶

Bases: object

A simple data container containing a generic measurement’s value, timestamp, and corresponding model stored as a MeasurementModel object. This container can be used as-is without inheritance.

Parameters:

value (np.ndarray) – the value of the measurement reading
stamp (float, optional) – timestamp, by default None
model (MeasurementModel, optional) – model for this measurement, by default None
state_id (Any, optional) – optional state ID, by default None

value¶

Container for the measurement value

Type:: numpy.ndarray

stamp¶

Timestamp

Type:: float

model¶

measurement model associated with this measurement.

Type:: navlie.types.MeasurementModel

state_id¶

Optional, ID of the state this measurement is associated.

Type:: Any

minus(y_check: ndarray) → ndarray¶

Evaluates the difference between the current measurement and a predicted measurement.

By default, assumes that the measurement is a column vector, and thus, the minus operator is simply vector subtraction.
