    • It is provided a method for generating a 3D representation of a scene, initially represented by a first video stream captured by a certain camera at a first set of viewing configurations. The method includes providing video streams compatible with capturing the scene by cameras, and generating an integrated video stream enabling three-dimensional display of the scene by integration of two video streams. The method includes calculating parameters characterizing a viewing configuration by analysis of elements having known geometrical parameters. The scene may be a sport scene which a playing field, a group of on- field objects and a group of background objects. The method includes segmenting a frame to those portions, separately associating each portion to the different viewing configuration, and merging them into a single frame. Also, the method may include calculating of on-field footing locations of on-field objects, computing new locations in a new frame, and transforming the on-field objects to the respective frame as a 2D object. Furthermore, the method may include synthesizing at on-field objects by segmenting portions of the object from respective frames of the first video stream, stitching the portions together and rendering the stitched object within a synthesized frame.
    • 提供了一种用于生成场景的3D表示的方法,该场景最初由在第一组观看配置下由某个相机拍摄的第一视频流表示。 该方法包括提供与通过照相机捕获场景兼容的视频流,以及通过集成两个视频流来生成能够进行场景三维显示的集成视频流。 该方法包括通过分析具有已知几何参数的元素来计算表征观看配置的参数。 该场景可以是一个运动场景,一个运动场,一组现场对象和一组背景对象。 该方法包括将帧分割到那些部分,将每个部分分别关联到不同的观看配置,并将它们合并成单个帧。 此外,该方法可以包括计算现场对象的现场基地位置,计算新帧中的新位置,以及将现场对象变换为相应的帧作为2D对象。 此外,该方法可以包括通过从第一视频流的各个帧分割对象的部分,将这些部分拼接在一起并在合成帧内渲染缝合对象来合成现场对象。
