Scene Locking in Vehicle-to-Vehicle Video Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle-to-vehicle networks, drivers face challenges in selecting and maintaining a particular scene of interest on a display due to the dynamic nature of video cameras capturing the scene briefly as vehicles move, leading to distraction and frequent searches among multiple video feeds.
Innovation Solution
A method and system that analyze key features in a selected video feed to identify and lock onto a specific scene, using image analysis logic to switch between video feeds from multiple cameras to ensure continuous display of the desired scene, even as the initial camera stops capturing it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver manually reviews available video feeds one at a time to find a scene of interest, then the driver can locate the desired scene, but the driver becomes distracted and must frequently repeat the process as cameras move relative to the scene
Solution Approach 1:
The system performs automatic scene locking without requiring continuous manual intervention from the driver. Once the driver selects a scene of interest, the scene locking logic automatically monitors multiple video feeds and switches between them to maintain continuous display of the selected scene, making the system self-regulating and eliminating the need for repeated manual searches
Solution Approach 2:
The system dynamically changes the displayed video feed parameter based on which camera is currently capturing the selected scene. The display logic continuously evaluates multiple video feeds and switches the active feed parameter to maintain the locked scene, adapting to the dynamic movement of vehicles and cameras in the network
2Adaptability or versatility
If multiple video cameras are used to capture different scenes, then scene coverage is improved, but the system complexity increases requiring logic to manage multiple feeds
Solution Approach 1:
The scene locking logic acts as an intermediary between multiple video cameras and the display device. It receives video feeds from multiple cameras, processes them through feature comparison and scene matching, and selectively outputs the appropriate feed to the display, simplifying the management of multiple cameras through a centralized control mechanism
Solution Approach 2:
The system implements continuous feedback by monitoring whether the currently displayed video feed still contains the locked scene features. The scene locking logic constantly compares key features of the locked scene against the current video feed and triggers a switch to an alternative feed when the scene is no longer visible, creating a closed-loop control system that automatically maintains scene continuity

AI summary
In V2V or other networks in which multiple video feeds are available to a participant, a participant can select a particular video feed for display. The participant has the option of selecting or locking onto a particular camera so that the display continues to show scenes captured by that camera without regard to what appears in those scenes. As an alternative, the participant may select or lock onto a particular scene. If a scene is selected, the current video feed is analyzed to identify key features. The video feed is monitored. If the key features disappear from the video feed, video feeds available from other cameras are analyzed for the presence of the key features. A new video feed (i.e., camera) is selected from the set of video feeds currently generating images including the key features.
