摘要： Disclosed are collision preventing apparatuses and methods for a vehicle. The collision preventing apparatus estimate whether objects located in a vicinity of the vehicle may collide with each other based on data collected from a sensor in the vehicle, determine a trajectory of each of the objects, verify whether the estimated trajectories intersect, determine that the objects may collide with each other in response to the estimated trajectories overlapping, inform each of the objects of a collision risk when the objects may collide with each other, and differently perform an operation of informing the objects of the collision risk based on a collision level of each of the objects.

摘要： A method and apparatus for controlling a vision sensor are provided. The apparatus and corresponding method are configured to predict an expected point, on a traveling path of a host vehicle, at which an illumination variation greater than or equal to a threshold is expected to occur, and determine whether the host vehicle is located within a threshold distance. The apparatus and corresponding method are also configured to control a vision sensor in the host vehicle based on the expected illumination variation in response to the host vehicle being located within the threshold distance.

摘要： A network connection control apparatus and method of a terminal for switching connection between heterogeneous networks depending on the data communication environment are provided. The communication network connection control method of a terminal includes measuring received signal strength and Internet Protocol (IP) packet transmission and reception amounts in a state where the terminal is connected to an IP network, switching, when the received signal strength is equal to or less than a predetermined received signal strength threshold, from the connection to the IP network to a connection to a cellular network, comparing, when the received signal strength is greater than the threshold, the IP packet reception amount with a predetermined reception threshold, and switching, when the IP packet reception amount is equal to or less than the reception threshold, from the connection to the IP network to the connection to the cellular network.

摘要： An object tracking apparatus is provided. The object tracking apparatus includes a processor configured to detect, from a first image frame, an amodal region including a first visible region in which a target object is visible and an occlusion region in which the target object is occluded, determine, based on the detected amodal region of the first image frame, that at least a partial region of a second image frame is a search region of the second image frame, the second image frame being temporally adjacent to the first image frame, and track the target object in the second image frame based on the determined search region.
