Virtual Viewpoint Playback Apparatus Automatic Camera Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual viewpoint image playback systems face challenges in efficiently managing and resetting the virtual camera to a predetermined initial position after each user's viewing, particularly in large-scale exhibitions where multiple users share a single device.
Innovation Solution
A playback apparatus that includes one or more processors to play back a virtual viewpoint image from a predetermined start timecode to a predetermined end timecode, using three-dimensional shape data and virtual viewpoint information. The apparatus controls the virtual viewpoint information differently during playback and initialization, and automatically initializes the timecode and resets the virtual camera to its initial position after each playback session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users share a single device at an exhibition, then user accessibility and device utilization are improved, but the complexity of manually resetting the virtual camera for each user increases
Solution Approach 1:
The system automatically detects when playback ends and autonomously resets the virtual camera to its initial position without requiring staff intervention. The playback apparatus monitors playback status and triggers initialization automatically, making the system self-servicing and eliminating manual reset operations.
Solution Approach 2:
The virtual camera is pre-configured with initial position information stored in the system. Before each playback session begins, the system prepares by having the initial position ready, allowing instant restoration without manual intervention when playback concludes.
2Reliability
If the virtual camera is manually reset after each user, then the next user can start from the initial position, but staff workload and time consumption increase
Solution Approach 1:
The playback apparatus automatically monitors playback status and triggers initialization when playback ends, eliminating the need for staff to manually reset the camera. This self-service mechanism ensures consistent initial positioning while eliminating time loss associated with manual operations.
Solution Approach 2:
The system continuously monitors playback status and uses this feedback to automatically trigger the initialization process when playback concludes, ensuring the virtual camera is always restored to its initial position without manual intervention and maintaining reliability across multiple user sessions.
3Productivity
If automatic initialization is implemented, then staff workload is reduced, but system control complexity increases
Solution Approach 1:
The system implements automatic detection of playback end status and autonomous execution of initialization routines. This self-service automation reduces staff workload and improves exhibition efficiency while the automation control complexity is managed through integrated system design that combines playback monitoring and camera initialization functions.

AI summary
A playback apparatus includes one or more memories storing instructions, and one or more processors executing the instructions to play back a virtual viewpoint image from a predetermined start timecode to a predetermined end timecode, the virtual viewpoint image being generated using three-dimensional shape data generated from images captured from a plurality of positions and virtual viewpoint information, control the virtual viewpoint information, and initialize timecode of the virtual viewpoint image to the predetermined start timecode in response to an end of playback of the virtual viewpoint image, wherein the virtual viewpoint information is controlled differently in playing back the virtual viewpoint image and in initializing the timecode.
