Abstract
An optimized method and apparatus for correcting for distortions in rendering add-on graphics within a streaming video feed comprising receiving a streaming video feed captured using a real camera, including an image frame capturing an image of a real asset having a size and a position within the image frame, the image frame being captured from a particular view point and having a particular field of view, the real camera introducing a plurality of measurable image distortions into the image frame, receiving set of camera instrumentation sensors data corresponding to the view point, the field of view, distortion parameters of the real camera, creating a virtual camera, generating add-on graphics having a size and an insertion position within the image frame, creating a first distortion grid having a first set of coordinate values, creating a second distortion grid having a second set of coordinate values wherein the second set of coordinate values are derived from the first set of coordinate values, using the second grid to distort the add-on graphics for image distortion, and compositing the distorted add-on graphics with the image frame.
