Abstract: Airborne tracking systems use sensors to track objects of interest. In order to track the objects of interests, the sensors need to be steered such that the object is kept, ideally, in the center of the sensors field of view. Automatic steering of optical sensors requires the generation of a track on an object of interest. When tracking boats on the water, current approaches to image processing may generate multiple detections on the object of interest. Embodiments of the present disclosure solve the track multiplicity problem by grouping tracks associated with the object of interest into a cluster and by estimating a most likely location of the object within the cluster of tracks. Based on the estimated location, embodiments of the present disclosure outputs a single track for the object. The single track is used by an automatic steering system to maintain a sensor aimed at the object of interest.

Abstract translation: 机载跟踪系统使用传感器跟踪感兴趣的物体。 为了跟踪感兴趣的对象，传感器需要被引导，使得物体理想地保持在传感器视场的中心。 光学传感器的自动转向需要在感兴趣的物体上产生轨迹。 当跟踪水上的小船时，目前的图像处理方法可能会对感兴趣的对象产生多个检测。 本公开的实施例通过将与感兴趣对象相关联的轨道分组为群集并且通过估计轨道簇内的对象的最可能位置来解决轨道多重性问题。 基于估计的位置，本公开的实施例为对象输出单个轨道。 单个轨道由自动转向系统使用以保持针对感兴趣对象的传感器。
