Multi-Camera Peppers Ghost Filming for Lifelike Telepresence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional peppers ghost filming and display systems suffer from poor image quality and difficulty in transmitting high-quality displays over limited bandwidth, especially in live communication transmissions, resulting in a lack of lifelike and immersive telepresence experiences.
Innovation Solution
The system enhances peppers ghost displays by optimizing video image acquisition, projection through semi-transparent screens, and using advanced lighting and camera setups to create a visually realistic and immersive telepresence experience, suitable for larger offices and public environments, with features like LED panels, Heads Up Displays, and augmented reality integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional filming and display methods are used for peppers ghost images, then the system is simpler to implement, but the image quality is lacking and does not produce a lifelike image
Solution Approach 1:
The system divides the filming process into multiple capture locations with dedicated cameras positioned at specific angles (front, side, rear) to capture different aspects of the subject. This segmentation allows each camera to optimize its specific viewing angle and lighting conditions, resulting in higher overall image quality while maintaining manageable system complexity through modular camera placement
Solution Approach 2:
The patent transitions from conventional 2D filming to multi-dimensional capture by positioning cameras at various heights and angles relative to the subject. The filming location includes a raised platform or stage area where cameras are positioned above and to the sides of the subject, creating a three-dimensional capture geometry that enhances the realism and depth of the final peppers ghost image
2Manufacturing precision
If high quality peppers ghost displays are transmitted over limited bandwidth, then the image quality and realism are improved, but the transmission becomes difficult and loses fidelity
Solution Approach 1:
The system creates multiple video images from the same subject performance using different cameras positioned at various locations. These multiple video signals can then be transmitted separately over the available bandwidth, allowing the receiving system to reconstruct a high-quality display by combining the information from multiple lower-quality individual transmissions, effectively overcoming bandwidth limitations
Solution Approach 2:
By dividing the video transmission into multiple separate video signals from different camera positions, the system allows parallel transmission over the available bandwidth. Each camera captures a specific aspect of the performance, and the combined information provides sufficient detail for high-quality display without requiring a single ultra-high bandwidth channel
3Manufacturing precision
If the filming location does not match the lighting conditions at the display stage, then the setup is simpler, but the projected image lacks perceived likeness to real original
Solution Approach 1:
The system performs preliminary lighting setup and calibration at the filming location before actual performance. The lighting arrangement is pre-configured to match the anticipated display conditions, and lighting controls are programmed in advance to replicate the lighting direction and quality used during capture. This preliminary preparation ensures accurate lighting matching without complex real-time adjustments during performance

Function Achieved in This Case
The system provides a more lifelike and immersive telepresence experience by ensuring high-quality image projection and transmission, allowing for interactive and remote viewing of virtual subjects with enhanced realism and clarity, even in bright environments.
Implementation Method 1
an image source arranged to project an image directly towards a semitransparent screen for receiving a film of an image and subsequently projected by the image source to generate a partially reflected image directed towards an audience
Data Source
AI summary
A system and method for filming and displaying a 3D image is provided, including acquisition of one or more video images at one or more capture locations of one or more subjects, the images being recorded as a data film for storage and playback, or transmission over a network, to a watching audience. The video images at the display venue are projected onto or through semi-transparent screens arranged to appear in front of a backdrop to a stage. The images may be displayed alongside or on the same stage as live performing talent, the projection perceived by the viewing audience as a virtual image. The semi-transparent screen is invisible to the watching audience or the cameras during the performance. The video image viewed by an online audience is perceived as bearing a close likeness to subject(s), providing a real presence of a virtual subject performing on a stage.
