Interface Summary
LocationSensor The interface LocationSensor should be implemented by objects which are sensors, that is, they generate Measurements.
 

Class Summary
AngleMeasurement The AngleMeasurement class captures am obsolute orientation such as a phased antenna array or a relative angle such as from a compass or tilt sensor.
CentroidTracker A class containing functionality to track a physical object or set of grouped physical objects where the tracked object is placed at the centroid of the position's of the last n sensors making measurements.
LinearDistanceMeasurement The LinearDistanceMeasurement class represents a linear distance measured between a sensor and an object.
LocationMath This class contains static mathematical routines for manipulating location and geometric information.
LocationReport A location report contains the location of an object and the uncertainty of that location.
MapMeasurement The MapMeasurement class captures a sensor measurement reporting the full x,y,z placement of an object.
MeanLocationReport A mean location report contains the mean State and standard deviation of for an object.
Measurement The Measurement class is a generic class from which the fundamental location measurements types inherit.
Measurement.TimestampComparator This class provides a comparator ordered by the timestamps of measurements, for example, in order to sort a list of Measurment objects by their timestamps.
MobileTracker A abstract class containing functionality to track a mobile physical object or mobile set of grouped physical objects.
MotionModel A generic motion model suitable for humans on foot.
OccupancyGrid An occupancy grid used by particle filters to find the number of discrete active grid cells in order to perform adaptive sampling.
ParticleFilterTracker A class containing functionality to track a physical object or set of grouped physical objects with a particle filter representing the location probability distribution and a motion model represents the object's motion patterns.
ParticleLocationReport A particle location report contains a list of all or some of the samples of the full particle filter for an object.
PlanarSweepMeasurement The PlanarSweepMeasurement Class contains the measurements from one planar sweep of a sensor.
PointTracker A class containing functionality to naively track a physical object or set of grouped physical objects where the tracked object is simply placed at the exact position the sensor making each new measurement.
ProximityMeasurement The ProximityMeasurement class represents a sensor reading of two objects which are nearby one another based on the limited range of a physical phenomenon (e.g. reception of an infrared emission).
Sample A Sample contains a state and an associated importance weight.
SmoothCentroidTracker A class containing functionality to track a physical object or set of grouped physical objects where the tracked object is placed at the centroid of the position's of the last n sensors making measurements, smoothed by the history of previous centroids.
State This class is and point estimate of an objet's location (translation and quaternion rotation) and its forward velocity in meters per seconds.
StateLocationReport A state location report contains a State of an object.
StateTransform This class represents a matrix transformation of the estimated or actual location (translation and rotation) an object.
StaticTracker A class containing functionality to track a static physical object or set of grouped physical objects.
Tracker An abstract class containing functionality to track a physical object.
TrueStateMeasurement The TrueStateMeasurement class is used to represent a ground truth measurement for evaluation purposes.
WorldMap The WorldMap class describes a coordinate system in which location computations occur.
