Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scene extension techniques in TV and cinema production, such as chroma-keying and projection screens, are limited by restrictive camera movements and composition issues, failing to seamlessly integrate virtual and real images in real-time, especially in live programs.
Innovation Solution
The system employs LED screens, a glass background, and motion-tracking cameras with sensors to create a panoramic studio environment, using software to distort and project images in real-time, allowing for seamless integration of virtual and real elements, with cameras and lenses tracking movements to ensure accurate perspective and distortion correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If chroma-keying is used to extend scenarios, then virtual images can be integrated with real images, but the technique is restricted to stationary or minimal camera movement
Solution Approach 1:
The system transitions from static chroma-keying to dynamic projection surfaces that move and deform in real-time according to camera position and movement. The projection surface is divided into multiple independently controllable panels that can be positioned at different angles and distances, allowing the system to adapt to various camera movements while maintaining image integration stability through real-time coordinate transformation.
Solution Approach 2:
The system employs optical sensors to detect camera position and movement in real-time, feeding this information back to the projection system. This feedback loop enables the projection surface to dynamically adjust its position, angle, and deformation parameters to match the camera's movement, thereby maintaining stable virtual-real image integration even during dynamic camera operations.
2Ease of operation
If projection screens are used to extend scenarios, then the technique is simpler and easier to apply, but camera movements are limited and wider movement shows the limits of the panel
Solution Approach 1:
The projection surface is divided into multiple independent panels or segments that can be individually positioned, angled, and controlled. This segmentation allows each panel to be optimized for specific camera views while collectively providing extensive coverage. The modular structure enables the system to accommodate wider camera movements by activating different panels in sequence or simultaneously at different positions.
Solution Approach 2:
The system extends the traditional 2D projection screen into a 3D spatial arrangement by positioning panels at various angles and distances from the camera. This dimensional transformation allows the projection surface to wrap around or surround the camera, providing immersive coverage that accommodates dynamic camera movements while maintaining implementation simplicity through standardized panel modules.
3Adaptability or versatility
If LED screens are arranged laterally and rotated to form panoramic environment, then studio perception is expanded and camera movement is fluid, but device complexity increases
Solution Approach 1:
The LED panels serve multiple functions simultaneously: they act as projection surfaces for virtual images, provide physical structural elements of the studio set, and can be independently controlled for different camera perspectives. This multi-functionality reduces the need for separate systems and justifies the added complexity by delivering versatile capabilities from integrated components.
Solution Approach 2:
The system dynamically adjusts panel parameters such as position, angle, rotation, and brightness in real-time based on camera movement and programming requirements. This parameter flexibility allows a single fixed physical installation to achieve various panoramic configurations and camera movement patterns, effectively managing complexity through software control rather than physical reconfiguration.
