Typedef Documentation

◆ dwCalibrationEngineHandle_t

typedef struct dwCalibrationEngineObject* dwCalibrationEngineHandle_t

Definition at line 63 of file CalibrationTypes.h.

◆ dwCalibrationRoutineHandle_t

Handles to calibration module objects.

Definition at line 62 of file CalibrationTypes.h.

◆ dwCalibrationStatusChanged

typedef void(* dwCalibrationStatusChanged) (dwCalibrationRoutineHandle_t routine, dwCalibrationStatus status, void *userData)

Enumeration Type Documentation

◆ dwCalibrationFastAcceptanceOption

enum dwCalibrationFastAcceptanceOption

Fast-acceptance options to configure calibration routines with.

If previously accepted estimates are available, fast-acceptance is a method to reduce re-calibration times in case the previous estimates can be validated with latest measurements. This option allows to configure the fast-acceptance behaviour of calibration routines supporting fast-acceptance

Enumerator
DW_CALIBRATION_FAST_ACCEPTANCE_DEFAULT	Let the calibration engine decide if fast-acceptance should be used.
DW_CALIBRATION_FAST_ACCEPTANCE_ENABLED	Unconditionally enable fast-acceptance (previously accepted estimates need to be available)
DW_CALIBRATION_FAST_ACCEPTANCE_DISABLED	Unconditionally disable fast-acceptance (previously accepted estimates will not be used)

Definition at line 139 of file CalibrationTypes.h.

◆ dwCalibrationSignal

enum dwCalibrationSignal

Defines signal types supported by a calibration routine.

Enumerator
DW_CALIBRATION_SIGNAL_POSE_SENSOR_TO_RIG	Pose-related signals and pose components.
DW_CALIBRATION_SIGNAL_POSE_SENSOR_TO_SENSOR	estimating a "sensor to rig" pose
DW_CALIBRATION_SIGNAL_POSE_ROLL	estimating "sensor to sensor" poses
DW_CALIBRATION_SIGNAL_POSE_PITCH	estimating the roll component of an orientation
DW_CALIBRATION_SIGNAL_POSE_YAW	estimating the pitch component of an orientation
DW_CALIBRATION_SIGNAL_POSE_X	estimating the yaw component of an orientation
DW_CALIBRATION_SIGNAL_POSE_Y	estimating the x component of a translation / direction
DW_CALIBRATION_SIGNAL_POSE_Z	estimating the y component of a translation / direction
DW_CALIBRATION_SIGNAL_VEHICLE_SPEED_FACTOR	estimating the z component of a translation / direction Vehicle-related signals
DW_CALIBRATION_SIGNAL_VEHICLE_WHEEL_RADII	estimating speed correction factor for CAN odometry
DW_CALIBRATION_SIGNAL_VEHICLE_FRONT_STEERING_OFFSET	estimating wheel radii

Definition at line 115 of file CalibrationTypes.h.

◆ dwCalibrationState

enum dwCalibrationState

Defines the current state of an individual calibration.

Enumerator
DW_CALIBRATION_STATE_NOT_ACCEPTED	The routine hasn't accepted an estimate.
DW_CALIBRATION_STATE_ACCEPTED	The routine has accepted an estimate and calibration continues.
DW_CALIBRATION_STATE_FAILED	The routine has failed calibration.

Definition at line 68 of file CalibrationTypes.h.
