Detailed Description

Enumeration Type Documentation

Status

enum Status

The tracking status of the TrackableBehaviour.

Enumerator
NO_POSE	Pose for the trackable could not be delivered.
LIMITED	The tracking is limited.
TRACKED	The trackable was tracked.
EXTENDED_TRACKED	The trackable was extended tracked.

StatusInfo

enum StatusInfo

Information on the tracking status. Gives the primary reason about the problem with tracking (STATUS::NO_POSE or STATUS::LIMITED).

Enumerator
NORMAL	Tracking is working normally.
NOT_OBSERVED	Target is not detected.
UNKNOWN	Unknown reason for limited status.
INITIALIZING	Not enough information yet for accurate tracking.
RELOCALIZING	The tracking system is currently relocalizing.
EXCESSIVE_MOTION	Moving too fast for accurate tracking.
INSUFFICIENT_FEATURES	Not enough features for accurate tracking.
INSUFFICIENT_LIGHT	Not enough light for accurate tracking.
RECOMMENDING_GUIDANCE	Could not snap the target. Recommend to show a Guide View overlay.
WRONG_SCALE	The target scale does not match the physical scale of the object.
MISSING_DATA	Asynchronous loading of the tracking data failed. Tracking quality might decrease or the tracking might be lost.

TrackingOptimization

enum TrackingOptimization

Optimize tracking quality and robustness for different target types.

Enumerator
DEFAULT	Best tracking performance for the majority of use cases and targets.
LOW_FEATURE_OBJECTS	Optimize tracking for objects with smooth, untextured surfaces, that lack features and detailed structures, including cars, sheet metal parts and many inustrial objects. Do not use for objects that move while being tracked.
AR_CONTROLLER	Optimize tracking for use cases where small, handheld fast moving targets are used like a AR/VR controller. Tracking will be less stable if the object is stationary.
