    • An embodiment of a system and method that inserts a virtual image into a sequence of video frames. The method includes capturing geometric characteristics of the sequence of video frames, employing the captured geometric characteristics to define an area of the video frames for insertion of a virtual image, registering a video camera to the captured geometric characteristics, identifying features in the sequence of video frames to identify the defined area of video frames for insertion of the virtual image, and inserting the virtual image in the defined area. Vanishing points are estimated to determine the geometric characteristics, and the virtual image is blended with the area of video frames prior to inserting the virtual image in the defined area.
    • 将虚拟图像插入到视频帧序列中的系统和方法的实施例。 该方法包括捕获视频帧序列的几何特征,采用所捕获的几何特征来定义用于插入虚拟图像的视频帧的区域,将摄像机注册到所捕获的几何特征,识别视频序列中的特征 帧以识别用于插入虚拟图像的视频帧的定义区域,以及将虚拟图像插入到定义的区域中。 估计消失点来确定几何特征,并且在将虚拟图像插入定义区域之前,虚拟图像与视频帧的区域混合。
