VR Image Editing via Spherical Projection Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VR image editing tools do not support intuitive editing of 360° images, as they distort when projected onto a plane, lacking functions like drawing or text insertion, and fail to provide real-time distortion review.
Innovation Solution
A display apparatus and control method that allow users to edit VR images by changing the shape and position of objects within the editing tool, using projection methods to maintain the integrity of the spherical image while editing on a planar representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spherical VR image is projected onto a plane for editing, then the image can be displayed and edited on a flat screen, but distortion occurs during the projection process
Solution Approach 1:
The patent applies spherical geometry to the editing process by creating a virtual spherical coordinate system that maps onto the planar display. Editing objects are positioned and sized according to spherical relationships, allowing intuitive editing on a flat screen while maintaining accurate spatial representation of the 360° VR image through spherical projection mathematics
2Adaptability or versatility
If existing photo editing tools are used on projected VR images, then basic editing functions are available, but the tools do not provide additional 360° image functions and editing does not match user intent due to distortion
Solution Approach 1:
The patent transforms editing parameters from Cartesian coordinates to spherical coordinates, changing the fundamental parameter system used by editing tools. Objects are positioned using azimuth and elevation angles instead of x-y coordinates, and sizing is based on angular dimensions, which maintains accurate spatial relationships in the 360° VR image while providing specialized functions for spherical content creation
3Loss of time
If editing is performed on a planar projection of a spherical image, then editing can be visualized on screen, but real-time distortion review is not possible
Solution Approach 1:
The patent implements real-time feedback by continuously calculating and displaying distortion information as the user performs editing operations. The system computes the projection distortion based on the current spherical to planar transformation parameters and provides visual feedback to the user, allowing immediate assessment and adjustment of editing decisions to achieve the desired final appearance in the 360° VR image
