Method and system for combining videos for display in real-time |
摘要 |
A system and method combines videos for display in real-time. A set of narrow-angle videos and a wide-angle video are acquired of the scene, in which a field of view in the wide-angle video substantially overlaps the fields of view in the narrow-angle videos. Homographies are determined among the narrow-angle videos using the wide-angle video. Temporally corresponding selected images of the narrow-angle videos are transformed and combined into a transformed image. Geometry of an output video is determined according to the transformed image and geometry of a display screen of an output device. The homographies and the geometry of the display screen are stored in a graphic processor unit, and subsequent images in the set of narrow-angle videos are transformed and combined by the graphic processor unit to produce an output video in real-time.
