Adaptive Panoramic Image Stitching via Quality Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panoramic imaging systems require manual operation and result in slow image capture and processing times, with challenges in finding suitable stitching locations for high-quality image generation.
Innovation Solution
An adaptive panoramic image generation system that uses an imaging device and processor to determine optimal stitching positions by calculating joint sum of squared differences and adjusting image capture positions, allowing for efficient image stitching and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If many images are captured with large overlap to ensure stitching quality, then stitching quality is improved, but image capture time and processing time increase significantly
Solution Approach 1:
The system calculates a stitching position quality measure for multiple candidate stitching positions in the overlapping region, uses this quality measure feedback to select the optimal stitching position, and determines the next image capture position based on the selected stitching position, creating a closed-loop adaptive process that resolves the contradiction between stitching quality and capture time
Solution Approach 2:
The system dynamically adjusts the image capture position based on real-time evaluation of stitching position quality measures, making the capture process adaptive rather than static, allowing optimization of both quality and time through dynamic decision-making
2Ease of operation
If manual turning of devices is required for panoramic capture, then ease of operation deteriorates, but device complexity remains simple
Solution Approach 1:
The system automatically determines optimal stitching positions and calculates quality measures without user intervention, making the device self-sufficient in optimizing the capture process, thereby improving ease of operation while managing complexity through automation
Solution Approach 2:
The system pre-calculates stitching position quality measures for multiple candidate positions before final stitching, allowing optimal decisions to be made in advance, which simplifies the user operation while the computational complexity is handled preliminarily
