Multi-Field-of-View Video Streaming Stitching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional moving cameras, such as PTZ cameras, typically provide only a single field-of-view at a time, limiting the user's ability to obtain an overview of non-contiguous surveillance regions and preventing simultaneous viewing of multiple field-of-views from multiple sensors.
Innovation Solution
A system and method that captures and stitches multiple field-of-views into a single video stream, allowing for the transmission of a comprehensive overview stream, even if the fields-of-view are not synchronized in time, using an image sensor and processing unit to receive user selections, capture images, and combine them into a single stream for display on a computing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single field-of-view is provided from a moving camera, then the camera structure remains simple, but the user cannot obtain an overview of non-contiguous surveillance regions
Solution Approach 1:
The patent combines multiple field-of-views from different camera positions into a single unified video stream. The system captures images from multiple predetermined positions and stitches them together to create a composite stream that presents an overview of non-contiguous surveillance regions, resolving the contradiction between simplicity and comprehensive coverage.
Solution Approach 2:
The system divides the surveillance area into multiple non-contiguous regions, each captured by the camera at different predetermined positions. These segmented views are then reassembled into a unified stream, allowing the user to perceive the overall environment without requiring a single continuous field-of-view.
2Adaptability or versatility
If preset tours are used to access multiple field-of-views, then the camera can visit predefined positions, but the user loses an overall perspective of the environment
Solution Approach 1:
Instead of presenting field-of-views sequentially through preset tours, the system merges multiple positions into a single simultaneous stream. This allows the user to view multiple perspectives at once while maintaining an overall perspective of the environment, eliminating the trade-off between multi-position access and situational awareness.
3Adaptability or versatility
If only one field-of-view is streamed at a time, then the data transmission remains simple, but the user cannot see the same FoV from multiple sensors side-by-side
Solution Approach 1:
The system merges multiple field-of-views from different sensors into a single consolidated stream rather than transmitting them as separate channels. This approach enables multi-sensor viewing capability while managing data volume efficiently by combining rather than multiplying the data streams.

AI summary
Methods and systems for providing a single stream including multiple FoVs. One system includes an image sensor configured to receive a selection of a plurality of field-of-views from a user, capture an image associated with each of the plurality of field-of-views, stitch the image associated with each of the plurality of field-of-views into a single stream, and transmit the single stream to at least one computing device.
