    • Disclosed are methods and apparatus for automatic visual detection of events, for recording images of those events and retrieving them for display and human or automated analysis, and for sending synchronized signals to external equipment when events are detected. An event corresponds to a specific condition, among some time-varying conditions within the field of view of an imaging device, that can be detected by visual means based on capturing and analyzing digital images of a two-dimensional field of view in which the event may occur. Events may correspond to rare, short duration mechanical failures for which obtaining images for analysis is desirable. Events are detected by considering evidence obtained from an analysis of multiple images of the field of view, during which time moving mechanical components can be seen from multiple viewing perspectives.
    • 公开了用于自动视觉检测事件的方法和装置,用于记录这些事件的图像并检索它们以进行显示和人或自动分析,以及当检测到事件时向外部设备发送同步信号。 事件对应于在成像设备的视野范围内的一些时变条件之中的特定条件,其可以通过基于捕获和分析二维视场的数字图像的视觉手段来检测,其中事件 可能发生。 事件可能对应于罕见的,短期的机械故障,其中获得用于分析的图像是期望的。 通过考虑从对视场的多个图像的分析获得的证据来检测事件,在此期间可以从多个观看视角看到移动机械部件。
