发明名称 SYSTEM AND METHOD OF INTEGRATING LIVE VIDEO INTO A CONTEXTUAL BACKGROUND
摘要 A live video feed is seamlessly inserted into a static background image while maintaining the proper positioning and scaling of the combined image. The current frame of the live video feed is first texturized onto a surface. The surface is a set of points that are translated to the location, e.g., latitude/longitude coordinates, of the live video source. A series of matrix transformations of the texturized surface coordinates is performed. First, the texturized surface is rotated to be tangential to the earth at the location of the live video source. Next, the texturized surface is rotated again to reflect the heading of the live video source. Lastly, the texturized surface is scaled to conform to the background image. The transformed live image is then inserted into the larger background image in its proper position and displayed.
