Systems and methods for detecting flashlights on one or more traffic signal devices are provided. The method includes capturing a series of images of one or more traffic signal elements in a traffic signal device over a period of time. The method further includes, for each traffic signal element, analyzing the series of images to determine one or more time periods during which the traffic signal element is in an open state or a closed state, and analyzing the time periods to determine one or more different open states and one or more different closed states. The method further includes identifying one or more cycles associated with the different on-states followed by the different off-states or the different off-states followed by the different on-states, and classifying the traffic signal element as a flash upon identifying a threshold number of adjacent cycles.
本发明提供了用于检测一个或多个交通信号装置上的闪光灯的系统和方法。该方法包括在一段时间内捕获交通信号装置中的一个或多个交通信号元件的一系列图像。该方法还包括,针对每个交通信号元件,分析一系列图像以确定交通信号元件处于打开状态或关闭状态的一个或多个时间段,并且分析该时间段以确定一个或多个不同的打开状态和一个或多个不同的关闭状态。该方法还包括识别与不同的打开状态紧接着不同的关闭状态或者不同的关闭状态紧接着不同的打开状态相关的一个或多个周期,并且在识别出阈值数量的相邻周期时,将交通信号元件分类为闪光灯。
