  • Graphical coordinate system transform for video frames
    Patent number: 10580148
    Abstract: A computing device is provided, which is configured with a processor configured to compute feature points in a new frame and a prior frame of a series of successive video frames, compute optical flow vectors between these frames, and determine a homography transform between these frames based upon the feature points and optical flow vectors. The processor is further configured to apply the homography transform to the graphical element coordinate system in the prior frame to generate an updated graphical element coordinate system in the new frame, and generate a six degree of freedom camera pose transform therebetween based on the homography transform and a camera pose of the graphical element coordinate system in the prior frame. The processor is further configured to render an updated graphical element in the new frame relative to the updated graphical element coordinate system using the six degree of freedom camera pose transform.
