Enumeration Type Documentation

POSITIONAL_TRACKING_STATE

enum POSITIONAL_TRACKING_STATE

strong

Lists the different states of positional tracking.

Enumerator
SEARCHING	\warn DEPRECATED: This state is no longer in use.
OK	The positional tracking is functioning normally.
OFF	The positional tracking is currently disabled.
FPS_TOO_LOW	The effective FPS is too low to provide accurate motion tracking results. Consider adjusting performance parameters (e.g., depth mode, camera resolution) to improve tracking quality.
SEARCHING_FLOOR_PLANE	The camera is currently searching for the floor plane to establish its position relative to it. The world reference frame will be set afterward.
UNAVAILABLE	The tracking module was unable to perform tracking from the previous frame to the current frame.

ODOMETRY_STATUS

enum ODOMETRY_STATUS

strong

Report the status of current odom tracking.

Enumerator
OK	The positional tracking module successfully tracked from the previous frame to the current frame.
UNAVAILABLE	The positional tracking module failed to track from the previous frame to the current frame.
LAST

SPATIAL_MEMORY_STATUS

enum SPATIAL_MEMORY_STATUS

strong

Report the status of current map tracking.

Enumerator
OK	The positional tracking module is operating normally.
LOOP_CLOSED	The positional tracking module detected a loop and corrected its position.
SEARCHING	The positional tracking module is searching for recognizable areas in the global map to relocate.
OFF	Spatial memory is disabled
LAST

POSITIONAL_TRACKING_FUSION_STATUS

enum POSITIONAL_TRACKING_FUSION_STATUS

strong

Report the status of the positional tracking fusion.

Enumerator
VISUAL_INERTIAL

INERTIAL_GNSS
UNAVAILABLE
LAST

POSITIONAL_TRACKING_MODE

enum POSITIONAL_TRACKING_MODE

strong

Lists the mode of positional tracking that can be used.

Enumerator
GEN_1	Default mode. Best compromise in performance.
GEN_2	Next generation of positional tracking, allow better accuracy.

REFERENCE_FRAME

enum REFERENCE_FRAME

strong

Lists possible types of position matrix used to store camera path and pose.

Enumerator
WORLD	The transform of sl::Pose will contain the motion with reference to the world frame (previously called PATH).
CAMERA	The transform of sl::Pose will contain the motion with reference to the previous camera frame (previously called POSE).
