360-Degree Video Stitching Guide for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 360-degree video capture technologies face challenges in maintaining high resolution and avoiding distortion at stitching regions, particularly when multiple cameras with different resolutions are used, leading to potential dislocation and discoloration of objects in the boundary regions.
Innovation Solution
A mobile terminal and operating method that provide a guide for the stitching region and resolution quality, allowing users to adjust camera positions to avoid stitching regions and ensure high-resolution capture by displaying stitching regions and camera resolution information, enabling users to turn the camera to prevent objects from being stitched and maintain high resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If multiple cameras are used to capture 360-degree video, then the view angle coverage is improved, but distortion and dislocation occur in stitching regions
Solution Approach 1:
The system performs preliminary actions by providing guidance information to users before capturing 360-degree video. The guidance indicates optimal camera orientations that minimize stitching regions over objects, allowing users to adjust camera position in advance to avoid distortion and dislocation in the final video.
2Adaptability or versatility
If cameras with different resolutions are used, then device versatility is improved, but resolution inconsistency occurs in stitched video
Solution Approach 1:
The system applies local quality by providing resolution information specifically for regions captured by different cameras. The guidance information indicates which areas of the scene will be captured by which cameras, allowing users to position important objects in regions captured by high-resolution cameras while accepting lower resolution in other areas.
3Manufacturing precision
If stitching regions are minimized, then video quality is improved, but device complexity increases
Solution Approach 1:
The system uses feedback by providing real-time or pre-capture guidance information to users about camera orientation and positioning. This feedback loop allows users to adjust camera position based on information about where stitching regions will occur, achieving high video quality without requiring complex automated stitching algorithms.
