Abstract
In one aspect, video latency reduction by real-time warping is described. In one aspect, an original geometric image model of a digital video frame is adjusted according to a video frame latency, to form an adjusted geometric image model. A geometric image model may represent a field of view from a remote camera used to capture the digital video frame. The adjusted geometric image model may be overlaid onto the original geometric image model to capture a warped image. In one aspect the warped image is re-projected according to the adjusted geometric image model to form a re-projected image. The re-projected image may then be displayed to approximate a real-time field of view from a camera used to capture the digital video frame. In one aspect, an attitude and runway alignment of an unmanned aerial vehicle may be controlled using a displayed, re-projected image. Other aspects are described and claimed.
