Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video surveillance systems lack spatial context, making it difficult for users to interpret video feeds within the larger surrounding area, as they only provide video feeds without contextual information.
Innovation Solution
Combining video surveillance with virtual 3D modeling and georeferencing techniques to overlay live video feeds onto accurate, georeferenced 3D models of monitored areas, allowing users to visualize the video in its true-to-life context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video surveillance systems provide only video feeds to users, then the system complexity is low, but the user cannot interpret the video feed within the larger surrounding context
Solution Approach 1:
The patent combines video surveillance feeds with virtual 3D models of the monitored area into a unified display system. The video feeds are overlaid onto the corresponding locations in the 3D model, allowing users to see both the detailed video content and the broader spatial context simultaneously. This merging resolves the contradiction by integrating multiple information sources without creating separate complex systems.
Solution Approach 2:
The virtual 3D model serves as an intermediary between the video feeds and the user. Instead of directly presenting raw video feeds without context, the system uses the 3D model as a mediator to provide spatial reference and contextualize the video content. This intermediary element adds spatial context information without requiring the user to mentally map multiple separate displays.
2Ease of operation
If prior art monitoring systems provide video feeds without contextual information, then the ease of operation is high, but the user has difficulty understanding or visualizing the monitored video in the context of the surrounding area
Solution Approach 1:
The patent transitions from traditional 2D video feed display to a 3D virtual model overlay system. By adding the third dimension (spatial context) to the flat video feeds, users can visualize the monitored area in its true-to-life context. This dimensional enhancement allows users to easily interpret video content while simultaneously understanding its location within the broader monitored area.
3Loss of information
If the system overlays video recording onto the virtual 3D model, then the situational awareness is enhanced, but the processing complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing the virtual 3D model of the monitored area before video feeds need to be overlaid. The georeferenced 3D model is created and stored in advance, with all spatial relationships and coordinate systems predetermined. When video feeds arrive, they can be quickly mapped to the existing model structure without requiring complex real-time processing, thus enhancing situational awareness while managing processing complexity.

AI summary
A video monitoring system and method comprises a first camera at a first camera location configured to video record a first monitored area, wherein a georeference location of the first monitored area is known, and a virtual 3D model of the monitored zone that includes the first camera location and the first monitored area, wherein the virtual 3D model is georeferenced to a physical location. The system further comprises a processor configured to receive the video recording of the first monitored area and to overlay the video recording of the first monitored area onto a part of the virtual 3D model that corresponds to the georeference location of the first monitored area. A display is also connected to the processor and configured to display the virtual 3D model of the monitored zone overlaid with the video recording of the first monitored area.
