Augmented Reality Wall Camera Viewer Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality and filmmaking technologies face challenges in providing real-time, immersive backgrounds that accurately respond to camera and viewer movements, leading to delays and reduced immersion in filmed scenes.
Innovation Solution
A system that combines camera and viewer tracking with real-time perspective shifting in projected augmented reality backgrounds, allowing for dynamic updates of the scene based on the camera's and viewer's positions, thereby enhancing immersion and reducing post-production delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional green screen filming is used, then post-production flexibility is improved, but immersion during filming deteriorates and re-shoots are required
Solution Approach 1:
The system pre-renders background scenes and prepares augmented reality content before filming begins. The virtual background is created in advance and then dynamically integrated with live-action footage, allowing directors to visualize the complete scene during filming without requiring post-production re-shoots.
Solution Approach 2:
A camera tracking system serves as an intermediary between the physical camera and the virtual background. The tracker attached to the camera communicates position and orientation data to the rendering system, which automatically adjusts the virtual background perspective to match camera movement, eliminating the need for manual post-production alignment.
2Reliability
If rendered scenes are displayed on large displays, then immersion is improved, but delay in real-time response worsens
Solution Approach 1:
The system replaces mechanical large display hardware with a digital projection system. Instead of physically moving or updating a large display screen in real-time, the solution uses software-based rendering that projects virtual backgrounds directly onto surfaces, achieving real-time responsiveness without mechanical delays.
Solution Approach 2:
The virtual background system dynamically adapts to camera movement through real-time tracking. As the camera moves, the rendered background automatically adjusts its perspective and position to maintain the illusion of depth and space, creating an immersive experience that responds instantly to camera motion without delay.
3Extent of automation
If computer vision techniques are used to detect positions, then automation is improved, but processing time worsens
Solution Approach 1:
The system extracts only the essential tracking information needed for background rendering from the camera data. Instead of performing full computer vision analysis of the entire scene, the tracker extracts specific position and orientation parameters that are then used directly by the rendering system, significantly reducing processing time while maintaining automation.
Data Source
AI summary
Systems, methods, and machine-readable media are disclosed. A computing device is in communications with a display and one or more trackers that determine a location of a camera relative to the display. The computing device generates a digital scene for presentation on the display such that one or more objects shown in the digital scene have suitable perspective for the location of the camera as determined by the tracker.
