Abstract
Methods and systems for combining multiple video streams are provided. Video feeds are received from multiple optical sensors, and homography information and/or corner metadata is calculated for each frame from each video stream. This data is used to mosaic the separate frames into a single video frame. Local translation of each image may also be used to synchronize the video frames. The optical sensors can be provided by an airborne platform, such as a manned or unmanned surveillance vehicle. Image data can be requested from a ground operator, and transmitted from the airborne platform to the user in real time or at a later time. Various data arrangements may be used by an aggregation system to serialize and/or multiplex image data received from multiple sensor modules. Fixed-size record arrangement and variable-size record arrangement systems are provided.
