Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simulation of three-dimensional images is used to change viewpoint angles, then viewpoint flexibility is improved, but calculation complexity increases and image fidelity is lost
Solution Approach 1:
The patent uses pre-captured images from multiple cameras as direct copies of real-world viewpoints, avoiding the need to simulate three-dimensional images through complex calculations. Each camera captures a real viewpoint, and these captured images are directly displayed or combined, eliminating the computational burden of rendering virtual viewpoints while maintaining image fidelity.
Solution Approach 2:
The patent extracts only the necessary viewpoint information by positioning cameras at specific locations around the subject. Instead of calculating all possible viewpoints, the system captures images from a有限 number of fixed camera positions and allows users to select from these pre-captured viewpoints, thereby reducing calculation complexity while maintaining viewpoint flexibility.
2Adaptability or versatility
If multiple cameras are used to record one object, then viewpoint coverage is improved, but data volume increases and processing complexity increases
Solution Approach 1:
The patent segments the viewing experience into discrete viewpoint options, where each camera captures a specific viewpoint. Instead of transmitting and processing continuous multi-view data, the system divides the scene into separate viewpoint segments (one per camera) and allows selective display of these segmented viewpoints, reducing the amount of data that needs to be processed and transmitted.
Solution Approach 2:
The patent uses a有限 number of cameras positioned at key viewpoints around the subject, capturing only the essential perspectives needed for multi-viewpoint display. This partial coverage approach provides sufficient viewpoint diversity for most applications without requiring exhaustive coverage from numerous cameras, thereby controlling data volume while maintaining adequate viewpoint coverage.
3Manufacturing precision
If post-production processing is used to generate virtual viewing-angle images, then image quality is improved, but processing time increases and live broadcasting capability is lost
Solution Approach 1:
The patent performs all necessary image capture and basic processing in advance, during the recording phase. Multiple cameras simultaneously capture images from different viewpoints, and these pre-captured images are stored ready for display. When viewing, the system simply retrieves and displays the pre-captured images without requiring real-time processing or generation, enabling live broadcasting capability while maintaining image quality.
4Manufacturing precision
If multi-viewpoint images are transmitted without compression, then image fidelity is improved, but network bandwidth requirement increases and transmission efficiency decreases
Solution Approach 1:
The patent extracts and transmits only the essential image data from each camera viewpoint, using selective display of pre-captured images. By allowing users to select from discrete viewpoint options rather than transmitting continuous multi-view data streams, the system reduces the amount of data that needs to be transmitted while maintaining adequate image fidelity for the selected viewpoints.
Data Source
AI summary
A system for displaying multi-viewpoint images includes a terminal device having a communication component, a user interface (UI) component and a processing component. The communication component receives an image and a polygonal image model for establishing the relationship between each image and a corresponding viewing angle; one of the viewpoint angles is the current viewpoint angle. The UI component generates a UI for presenting the correspondence between the image of the current viewpoint angle and its viewpoint angle; the correspondence is used for selecting a target-viewpoint angle from the viewpoint angles. The processing component generates a switch instruction based on the target-viewpoint angle and allows UI to present an image corresponding to the target-viewpoint angle after UI presents an interval image being an image of an interval viewpoint angle between the current viewpoint angle and the target-viewpoint angle and is generated based on the image of the target-viewpoint angle.
