Multi-Camera Video Stitching for Immersive Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video surveillance systems lack an intuitive way for security personnel to track objects moving between multiple camera views, requiring manual switching and lacking an immersive display of information from adjacent cameras.
Innovation Solution
A system that uses a processing circuit to detect corners in images from multiple cameras, correlate these points to calculate transformation functions, and stitch video from different cameras to provide an immersive, interactive display on a single electronic screen, allowing users to change vantage points seamlessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple camera displays are arranged on a bank of monitors with labels and overhead maps, then security personnel can view content from different cameras, but it becomes difficult to intuitively track objects moving between cameras and requires manual switching and memory of monitor locations
Solution Approach 1:
The patent merges multiple camera views into a single composite display that shows all camera feeds simultaneously with their spatial relationships preserved. This allows security personnel to view content from different cameras on one screen rather than switching between multiple monitors, maintaining spatial context and enabling intuitive object tracking across camera boundaries.
Solution Approach 2:
The patent adds a spatial dimension to the display by showing camera locations and fields of view overlaid on a map or floor plan. This visual representation provides spatial context that helps personnel understand the physical layout and track objects moving between cameras by following their paths on the map overlay rather than relying on memory of monitor positions.
2Productivity
If conventional surveillance systems use separate monitors for each camera with manual switching, then system complexity is reduced, but surveillance efficiency and user experience deteriorate due to lack of immersive display and intuitive object tracking
Solution Approach 1:
The patent creates a universal display interface that can show multiple camera views simultaneously while providing both individual camera monitoring and comprehensive scene overview capabilities. The system integrates map overlay, camera selection, and object tracking functions into a single interface, allowing security personnel to perform multiple surveillance tasks without switching between different systems or displays.
3Loss of time
If security personnel manually switch between monitors to track moving objects, then device complexity is minimized, but time is lost due to manual switching and the need to remember monitor-camera associations
Solution Approach 1:
The patent performs preliminary spatial arrangement and labeling of camera views in the composite display, organizing them according to their physical locations before the user needs to track an object. This pre-organization allows security personnel to immediately understand camera positions and relationships without needing to remember associations or perform manual configuration, enabling faster object tracking across camera boundaries.

AI summary
A system for providing stitched video from a first camera and a second camera to an electronic display system includes a processing circuit configured to associate a view a first camera with an approximate location. The processing circuit is further configured to build relationship data between the first camera and a second camera using the approximate location. The processing circuit is further configured to transform video from the first camera relative to video from the second camera, the transformation based on the relationship data. The processing circuit is further configured to use the transformed video to cause the stitched video to be provided to the electronic display system.
