struct Tracklet

Tracklet structure

Contains tracklets from object tracker output.

Public Types

enum class TrackingStatus : std::int32_t

Values:

enumerator NEW: The object is newly added.

enumerator TRACKED: The object is being tracked.

enumerator LOST: The object gets lost now. The object can be tracked again automatically(long term tracking) or by specifying detected object manually(short term and zero term tracking).

enumerator REMOVED: The object is removed.

Public Functions

DEPTHAI_SERIALIZE(Tracklet, roi, id, label, age, status, srcImgDetection, spatialCoordinates, velocity, speed)

Public Members

Rect roi: Tracked region of interest.

std::int32_t id = 0: Tracklet’s ID.

std::int32_t label = 0: Tracklet’s label ID.

std::int32_t age = 0: Number of frames it is being tracked for.

TrackingStatus status = TrackingStatus::LOST : Status of tracklet.

ImgDetection srcImgDetection: Image detection that is tracked.

Point3f spatialCoordinates: Spatial coordinates of tracklet.

std::optional<Point3f> velocity: Estimated 3D velocity of the tracklet in m/s. nullopt when spatial data is unavailable.

std::optional<float> speed: Magnitude of the estimated 3D velocity in m/s. nullopt when spatial data is unavailable.
