Field Detail

• onAlerts

  Explain this code

  public final LSDWeakCallbacks<List<LSDAlert>> onAlerts

  Callback for results from LSDAlertManager.determineAlerts(java.util.List<com.here.see.livesense.common_lib.detection.LSDObjectRecognition>, int, int, int, java.util.Date)

• onLaneAlerts

  Explain this code

  public final LSDWeakCallbacks<List<LSDAlert>> onLaneAlerts

  Callback for results from LSDAlertManager.determineLaneAlerts(java.util.List<com.here.see.livesense.domain.Recognition>, int, int, int, java.util.Date)

Constructor Detail

• LSDAlertManager

  public LSDAlertManager()

Method Detail

• setRoi

  Explain this code

  public void setRoi(Roi roiPtr)

• setCameraProperties

  Explain this code

  public void setCameraProperties(LSDCameraProperties cameraProperties)

  Set properties of camera used for detections, if not set, then only a subset of alerts will be produced.

  Parameters:

  cameraProperties - Properties of camera used for detections

• setAlertSettings

  Explain this code

  public void setAlertSettings(LSDAlertSettings alertSettings)

• setMinimumSpeed

  Explain this code

  public void setMinimumSpeed(float minimumSpeed)

  Set minimum speed threshold for proximity alerts to trigger. Alerts will not trigger when current speed is below minimumSpeed

  Parameters:

  minimumSpeed - speed in meters per second

• setCurrentSpeed

  Explain this code

  public void setCurrentSpeed(float currentSpeed)

  Set current speed of vehicle

  Parameters:

  currentSpeed - speed in meters per second

• setTimeToCollisionAlert

  Explain this code

  public void setTimeToCollisionAlert(float timeInSeconds)

  Set time to collision threshold under which a collision should be considered a danger.

  Parameters:

  timeInSeconds - time in seconds

• setTimeToCollisionWarning

  Explain this code

  public void setTimeToCollisionWarning(float timeInSeconds)

  Set time to collision threshold under which a collision should be considered a warning. Value should be greater than time to collision alert for meaningful output.

  Parameters:

  timeInSeconds - time in seconds

• setCollisionBufferDistance

  Explain this code

  public void setCollisionBufferDistance(float collisionBufferDistance)

  Set the buffer distance, in meters, used during collision calculations.

  This distance represents the distance between the camera position and the front of the vehicle.

  The default buffer distance is 2.5 meters.

  Parameters:

  collisionBufferDistance - Buffer distance in meters. A negative value will set buffer distance to 0.

• determineAlerts

  Explain this code

  public List<LSDAlert> determineAlerts(List<LSDObjectRecognition> recognitions,
                                        int frameWidth,
                                        int frameHeight,
                                        int sensorOrientation,
                                        Date frameDateTime)

  Determine if any alerts should be generated for a frame of detections. Returned List is same as given by LSDAlertManager.onAlerts callback.

  Parameters:

  recognitions - Recognitions to process

  frameWidth - Width of detection frame

  frameHeight - Height of detection frame

  sensorOrientation - Relative rotation of detection frame

  frameDateTime - Timestamp of frame

  Returns:

  List of Alerts for processed recognitions, empty list if no new alerts.

• determineLaneAlerts

  Explain this code

  public List<LSDAlert> determineLaneAlerts(List<Recognition> recognitions,
                                            int frameWidth,
                                            int frameHeight,
                                            int sensorOrientation,
                                            Date frameDateTime)

  Determine if any lane-related alerts should be generated for a frame of lane detections.

  The returned list is the same as given by the lane alerts callback.

  The alerts generated by this method are independent from LSDAlertManager.determineAlerts(List, int, int, int, Date).

  This method does nothing if recognitions does not contain lane detections or there is insufficient lane information in the available lane detections.

  NOTE:This feature is in Beta and the API may change without notice.

  Parameters:

  recognitions - Lane recognitions to process

  frameWidth - Width of detection frame

  frameHeight - Height of detection frame

  sensorOrientation - Relative rotation of detection frame

  frameDateTime - Timestamp of frame

  Returns:

  List of alerts for processed lane recognitions, empty list if no new alerts
