  • Publication number: 20240202930
    Abstract: A vehicle according to an embodiment includes: a sensor including one or more sensors configured to obtain information about a target object present around the vehicle; and a sensor information fusion device including a processor configured to control to generate or maintain a sensor fusion track using the information about the target object provided by the sensing device, wherein the processor is configured to control to determine a length of the sensor fusion track using a partial LiDAR (PL) track in which only a portion of the target object is detected in a boundary area of the sensors and estimate an edge point in a shape reconstructed based on the determined length of the sensor fusion track.

  • Publication number: 20230258792
    Abstract: An embodiment object tracking method by use of sensor fusion technology includes creating a LiDAR track that tracks an object according to point clouds extracted from LiDAR data of the object, creating a non-final sensor fusion track for the object according to camera data or radar data in addition to the LiDAR data, assessing consistency of a heading angle of the LiDAR track, and determining the heading angle of the LiDAR track to be a heading angle of a final sensor fusion track according to a result of assessing the consistency.
