    摘要: A method used in broadcasts of events is disclosed for identifying the coordinates of an object in world space from a video frame, where the object is not on the geometric model of the environment. Once the world coordinates of the object are identified, a graphic may be added to a video replay showing the object. The method may also be expanded in a further embodiment to identify a trajectory of an object over time moving through world space from video images of the start and end of the trajectory, where the object is not on the geometric model of the environment. Once the trajectory of the object in world space is identified, a graphic may be added to a video replay showing the trajectory.

    摘要: Metadata associated with a video is used to enhance a display of the video. A fingerprint is calculated using a particular fingerprint algorithm for one or more frames or images of the video. The fingerprint is associated with metadata for the one or more frames or images, and the fingerprint and the associated metadata are stored in a metadata repository. When a user requests enhancement of a video at a client device, the client device will calculate a fingerprint for one or more frames or images of the video to be enhanced using the same fingerprint algorithm and use the calculated fingerprint to access metadata associated with that fingerprint in the metadata repository. The accessed metadata is used to enhance a display of the video based on the user request.

    摘要: The path and/or position of an object is tracked using two or more cameras which run asynchronously so there is need to provide a common timing signal to each camera. Captured images are analyzed to detect a position of the object in the image. Equations of motion for the object are then solved based on the detected positions and a transformation which relates the detected positions to a desired coordinate system in which the path is to be described. The position of an object can also be determined from a position which meets a distance metric relative to lines of position from three or more images. The images can be enhanced to depict the path and/or position of the object as a graphical element. Further, statistics such as maximum object speed and distance traveled can be obtained. Applications include tracking the position of a game object at a sports event.
