Mobile Device Video Stream Access via Field of View Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video surveillance systems require time-consuming formal launching procedures to access video data streams between devices, which can lead to delays in tracking objects of interest and sharing views between users, potentially causing users to lose track of the object or miss critical moments.
Innovation Solution
A method where a mobile device scans and matches the field of view of a video data stream on a monitoring station with pre-captured camera markers to directly retrieve the video data stream from its source, eliminating the need for detailed source information and enabling instant access and sharing of video data streams across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If formal launching procedures (entering username, password, device details) are used to access video data streams, then security and authentication are ensured, but access time increases considerably
Solution Approach 1:
The system performs preliminary authentication by capturing the field of view displayed on the monitoring station screen and matching it with pre-stored camera markers. This preliminary action establishes authentication credentials in advance, allowing direct access to video data streams without requiring formal launching procedures at the time of access.
Solution Approach 2:
The system creates a visual copy (screenshot or field of view capture) of the monitoring station display and matches it against stored camera markers. This copying mechanism enables the mobile device to identify and access the desired video stream through visual recognition rather than through formal authentication procedures.
2Adaptability or versatility
If formal launching is required to assign video views to other users, then user authorization is properly managed, but the sharing process becomes time-consuming
Solution Approach 1:
The system provides visual feedback by displaying the field of view from the monitoring station on the mobile device screen. This visual feedback mechanism allows users to confirm they are viewing the correct stream while enabling rapid sharing with other users without requiring formal authorization procedures.
Solution Approach 2:
The system uses the displayed field of view as an intermediary between the monitoring station and the mobile device. This visual intermediary enables direct video stream assignment to other users through the matching process, bypassing traditional authorization workflows while maintaining proper user management.
3Ease of operation
If users move from monitoring station to target location to track objects, then mobility and flexibility are improved, but continuous monitoring is compromised due to access delays
Solution Approach 1:
The system replaces the mechanical interaction of physically being at the monitoring station with an optical/electronic field of view capture and matching mechanism. Users can point their mobile device camera at the monitoring station screen to capture the field of view, which is then matched with stored markers to establish direct video stream access, enabling mobility without compromising monitoring continuity.
Data Source
AI summary
Systems and methods for directly accessing video data streams and data between devices in a video surveillance system can include a first camera of a mobile device capturing an image of a field of view of a video data stream displayed on a second device, the mobile device matching the field of view with a source of the video data stream, and responsive to matching the field of view with the source, the mobile device retrieving the video data stream directly from the source.
