Georegistered Video Metadata Distribution for Aerial Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern battlefield surveillance systems face challenges in identifying features and distributing intelligence information, particularly video data, due to large file sizes and bandwidth limitations, which restricts the delivery of imagery to remote locations from the control center.
Innovation Solution
A method and apparatus for capturing and distributing broadband data, including time-tagged video frames and sensor metadata, which are georeferenced by combining with geographic information to create enhanced metadata files, allowing for efficient processing and display on user devices with varying capabilities, enabling the distribution of georegistered video and imagery to remote locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video data is transmitted from the AV to remote locations, then intelligence information distribution is improved, but transmission bandwidth requirements increase significantly
Solution Approach 1:
The patent segments video data transmission by delivering only essential metadata (georegistration parameters, timing information, sensor data) to remote locations, while the actual video frames are processed and displayed using locally available reference imagery. This segmentation reduces transmission bandwidth from requiring full video streams to only transmitting compact metadata packets.
Solution Approach 2:
The patent extracts and transmits only the critical georegistration metadata from the complete video data set. By separating the essential spatial-temporal registration information from the full video content, the system transmits minimal data while enabling remote devices to reconstruct georegistered displays using local reference imagery.
2Measurement precision
If full-resolution video is processed and displayed on remote devices, then image quality is improved, but computing power requirements increase
Solution Approach 1:
The patent uses locally stored reference imagery as a copy or template that remote devices use to reconstruct the georegistered display. Instead of transmitting and processing full-resolution video frames, the system uses the reference imagery copy at the remote device to render the georegistered view, significantly reducing computational requirements while maintaining display quality.
3Difficulty of detecting and measuring
If georegistration metadata is transmitted to remote locations, then feature identification capability is improved, but data transmission requirements increase
Solution Approach 1:
The patent transmits georegistration metadata in optimized parameter formats that enable remote devices to perform feature identification. By encoding spatial transformation parameters, timing synchronization data, and sensor metadata in compact forms, the system improves feature identification capability while minimizing data transmission requirements.

AI summary
A system and method for preparing for distribution to, distributing to and/or use by one or more devices broadband data associated with intelligence information garnered from an aerial vehicle (“AV”): The method may include obtaining from sensors coupled to the AV video depicting an area of surveillance, obtaining metadata associated with the video, aligning, temporally, the video and metadata, using reference information to align, spatially, the video and metadata, forming for distribution to the at least one device enhanced metadata as a function of the video, metadata and reference information, wherein the enhanced metadata is operable to enable displaying at the devices at least a portion of the video, whereby after receiving a distribution of the enhanced metadata, the devices are operable to display such portion of the video.
