Abstract: The present invention provides a battery safety test device includes: a mechanical switch element having one end connected to either a battery positive or negative electrode and the other end connected to an electronic switching element; the electronic switching element having one end connected to the mechanical switch element and the other end connected to the other of the battery positive or negative electrode; a voltage sensor for measuring a voltage of the battery after the mechanical switch element and the electronic switching element are turned on; and a current sensor for measuring a current of the battery after the mechanical switch element and the electronic switching element are turned on.

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.
