Electronic Device Viewpoint Selection for Multi-Camera Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for displaying videos from multiple camera viewpoints in sports or performances lack the ability to effectively allow users to select and view specific player or performer perspectives, limiting the immersive experience and engagement.
Innovation Solution
A system that includes cameras mounted on players or performers transmitting video data along with motion and location information to a server, which stabilizes and processes the data to generate user interface information for selecting desired viewpoints, allowing users to choose and display specific videos on electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple camera viewpoints are transmitted simultaneously, then users can select from more perspectives, but system complexity and data transmission load increase
Solution Approach 1:
The system segments video data from multiple cameras into separate streams, each with associated metadata (position, orientation, timestamp). This allows independent processing and selection of individual camera viewpoints without requiring simultaneous processing of all data, reducing system complexity while maintaining versatility.
Solution Approach 2:
A server acts as an intermediary between cameras and user devices. The server receives video data from multiple cameras, processes metadata, and delivers selected video streams to users based on their choices. This intermediary layer simplifies the architecture by centralizing data management and reducing direct peer-to-peer complexity.
2Speed
If video data from moving cameras is transmitted directly, then real-time viewpoints are provided, but video stability deteriorates
Solution Approach 1:
The system performs preliminary stabilization processing on video data from moving cameras before transmission. Metadata including camera position and orientation is processed in advance to enable compensatory transformations, ensuring stable video output while maintaining real-time transmission capabilities.
Solution Approach 2:
The system uses feedback from metadata (camera position, orientation, acceleration data) to dynamically adjust video stabilization parameters. This closed-loop approach allows real-time compensation for camera movement, maintaining both speed and stability.
3Adaptability or versatility
If cameras are mounted on body parts for first-person videos, then immersive experience is improved, but user comfort and practicality worsen
Solution Approach 1:
The system supports multiple camera mounting configurations (body-mounted, handheld, fixed positions) through a universal platform that processes video data from any source. This allows users to choose the most comfortable mounting method while still achieving immersive first-person perspective experiences.
Solution Approach 2:
Instead of requiring physical body mounting for all users, the system captures first-person videos from selected users and transmits them to other users' devices. This creates a virtual copying of the immersive experience, allowing users to view first-person perspectives without wearing cameras themselves.
