    • Techniques are described for tracking moving objects using a plurality of security cameras. Multiple cameras may capture frames that contain images of a moving object. These images may be processed by the cameras to create metadata associated with the images of the objects. Frames of each camera's video feed and metadata may be transmitted to a host computer system. The host computer system may use the metadata received from each camera to determine whether the moving objects imaged by the cameras represent the same moving object. Based upon properties of the images of the objects described in the metadata received from each camera, the host computer system may select a preferable video feed containing images of the moving object for display to a user.
    • 描述了使用多个安全摄像机跟踪移动物体的技术。 多个相机可以捕获包含移动物体的图像的帧。 这些图像可以由相机处理以创建与对象的图像相关联的元数据。 每个摄像机的视频馈送和元数据的帧可以被发送到主机系统。 主计算机系统可以使用从每个摄像机接收的元数据来确定由摄像机成像的移动物体是否表示相同的移动物体。 基于从每个摄像机接收到的元数据中描述的对象的图像的属性,主计算机系统可以选择包含用于显示给用户的移动物体的图像的优选视频馈送。

    • Embodiments of the disclosure provide for systems and methods for creating metadata associated with a video data. The metadata can include data about objects viewed within a video scene and/or events that occur within the video scene. Some embodiments allow users to search for specific objects and/or events by searching the recorded metadata. In some embodiments, metadata is created by receiving a video frame and developing a background model for the video frame. Foreground object(s) can then be identified in the video frame using the background model. Once these objects are identified they can be classified and/or an event associated with the foreground object may be detected. The event and the classification of the foreground object can then be recorded as metadata.
    • 本公开的实施例提供了用于创建与视频数据相关联的元数据的系统和方法。 元数据可以包括关于在视频场景内观看的对象的数据和/或在视频场景内发生的事件。 一些实施例允许用户通过搜索记录的元数据来搜索特定对象和/或事件。 在一些实施例中,通过接收视频帧并开发视频帧的背景模型来创建元数据。 然后可以使用背景模型在视频帧中识别前景对象。 一旦识别出这些对象,就可以对它们进行分类和/或可以检测与前景对象相关联的事件。 然后可以将事件和前景对象的分类记录为元数据。
