Geospatial Metadata Overlay for Video Situational Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in effectively communicating and processing georeferenced video data, providing situational awareness, and accurately tracking objects within georeferenced video feeds, especially when dealing with varying position accuracy and large amounts of data.
Innovation Solution
A video processing system that includes a display, geospatial database, and video processor, which overlays selected geospatially-tagged metadata onto a viewable area, providing indicators for locations outside the viewable area, and allows for real-time tracking and correction of geospatial metadata across multiple video feeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If georeferenced video data is displayed with all available metadata, then information completeness is improved, but user interface complexity and difficulty of communication increase
Solution Approach 1:
The patent extracts and separates specific geospatial metadata elements (such as location markers, coordinate information, and geotagged annotations) from the complete video data stream. This allows selective display of relevant metadata without overwhelming the user interface, maintaining information completeness while improving ease of operation through targeted information presentation.
Solution Approach 2:
The patent segments geospatial metadata into distinct, manageable components that can be independently processed and displayed. By dividing the metadata into separate elements (spatial coordinates, temporal markers, annotation data), the system can selectively render only the most relevant portions, reducing interface complexity while preserving essential information.
2Loss of information
If multiple independent map displays are arranged to maximize situational awareness, then information presentation is improved, but device complexity and screen space requirements increase
Solution Approach 1:
The patent merges multiple map display functions into a single integrated display interface. By combining situational awareness information, video feeds, and geospatial metadata into one unified display, the system maintains comprehensive information presentation while reducing device complexity and optimizing screen space utilization compared to multiple independent displays.
3Measurement precision
If image registration is performed to correct geospatial accuracy, then position precision is improved, but processing time and computational complexity increase
Solution Approach 1:
The patent performs preliminary geospatial calibration and registration during the video capture and initial processing phase. By pre-establishing accurate geospatial references and performing registration operations before final display or analysis, the system achieves high position precision without adding processing delays during critical operational phases.
4Loss of information
If geospatial metadata is overlaid on video feeds, then situational awareness is improved, but visual clarity and object tracking may be degraded
Solution Approach 1:
The patent applies local quality by selectively overlaying geospatial metadata only in specific regions or contexts where it provides value. By controlling the placement, density, and visibility of metadata overlays based on local display conditions and user needs, the system maintains situational awareness while preserving visual clarity and object tracking accuracy in critical areas.
Data Source
AI summary
A video processing system may include a display, at least one geospatial database, and a video processor. The video processor may cooperate with the display and the at least one geospatial database and be configured to display a georeferenced video feed on the display and defining a viewable area, and to overlay selected geospatially-tagged metadata onto the viewable area and relating to a geolocation outside the viewable area.
