摘要:

事件摄像机是对象跟踪应用的理想选择,因为它们能够捕获快速移动的对象,同时减少延迟和数据冗余。现有的基于事件的聚类和特征跟踪方法的监视和目标检测的工作,以及在大多数情况下,但在海洋环境中的不足。我们对海上船舶检测和跟踪的应用需要一个过程,该过程可以识别特征并输出表示该特征是由船舶产生的可能性的置信度分数,这可能会触发后续警报或激活分类系统。然而,海洋环境提出了独特的挑战,例如波浪倾向于产生大多数事件,需要大部分计算处理并产生误报检测。通过过滤冗余事件并分析每个事件簇的运动,我们可以识别和跟踪船只,同时忽略较短的寿命和不稳定的特征,如波浪产生的特征。

英文摘要:

Event cameras are ideal for object tracking applications due to their ability to capture fast-moving objects while mitigating latency and data redundancy. Existing event-based clustering and feature tracking approaches for surveillance and object detection work well in the majority of cases, but fall short in a maritime environment. Our application of maritime vessel detection and tracking requires a process that can identify features and output a confidence score representing the likelihood that the feature was produced by a vessel, which may trigger a subsequent alert or activate a classification system. However, the maritime environment presents unique challenges such as the tendency of waves to produce the majority of events, demanding the majority of computational processing and producing false positive detections. By filtering redundant events and analyzing the movement of each event cluster, we can identify and track vessels while ignoring shorter lived and erratic features such as those produced by waves.
