VR System Position-Based Panoramic Image Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems lack efficient methods for generating and managing multi-viewpoint images from celestial-sphere cameras, leading to awkward viewing experiences due to the display of hemispherical images, which are not naturally suited for human perception.
Innovation Solution
A virtual reality system comprising an image capturing device, a communication terminal, and a VR terminal that inputs and transmits position information and image identification data, allowing the VR terminal to select and display images based on the user's position, converting hemispherical images into spherical panoramic images using OpenGL ES and displaying them as planar images to mitigate the awkwardness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hemispherical images are displayed directly from celestial-sphere cameras, then the complete spherical field of view is captured, but the viewing experience becomes awkward and unnatural for human perception
Solution Approach 1:
The patent segments the hemispherical image data into multiple planar panoramic images representing different viewpoints. Instead of displaying the complete hemisphere at once, the system divides it into discrete selectable views that can be presented in a natural planar format, resolving the contradiction between comprehensive coverage and comfortable viewing.
Solution Approach 2:
The patent transforms the three-dimensional hemispherical projection into two-dimensional planar panoramic representations. This dimensional conversion allows the spherical field of view to be preserved while presenting the content in a format naturally suited for human visual perception on flat displays.
2Adaptability or versatility
If multiple viewpoint images are generated and managed, then immersive virtual reality experience is enhanced, but system complexity increases
Solution Approach 1:
The patent creates a universal image management system that handles multiple viewpoint images through standardized processes. The same generation, transmission, and selection mechanisms work across all viewpoints, reducing overall system complexity despite the multi-viewpoint capability.
Solution Approach 2:
The patent introduces an intermediary selection mechanism that manages the complexity of multiple viewpoint images. This intermediary layer handles the coordination between image generation, transmission, and display, simplifying the overall management of multi-viewpoint content.
3Ease of operation
If position information is tracked and used to select images, then natural viewing experience is achieved, but data processing requirements increase
Solution Approach 1:
The patent performs preliminary organization of position information and image data associations before actual viewing. By pre-establishing the relationships between viewer position and corresponding panoramic images, the system minimizes real-time processing requirements while maintaining natural viewing experience.

AI summary
A VR system includes an image capturing device, a communication terminal, a communication management system, and a VR terminal. The communication terminal is configured to input position information of the image capturing device, and transmit, to the communication management system, the position information of the image capturing device and image identification. The communication management system is configured to receive the position information of the image capturing device and the image identification information, and transmit, to the VR terminal, the position information and the image identification information. The VR terminal is configured to store, for each of a plurality of communication terminals, the position information of the image capturing device and the image identification information, select the position information of the image capturing device according to a position of the VR terminal, and display an image of image data indicated by particular image identification information associated with the selected position information.
