Panoramic Image Stitching with Dual-Memory Load Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panoramic image generation methods require significant memory resources due to the dynamic loading and unloading of images, which can lead to inefficiencies and memory overload during the stitching process.
Innovation Solution
A panoramic image generation apparatus and method that optimizes memory usage by employing a first memory unit for active image stitching and a second memory unit for storage, with a controlled loading and unloading process to manage memory load efficiently, utilizing low-resolution images and three-dimensional space region disposition for stitching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If all photographing images are loaded into memory for stitching processing, then stitching quality is improved, but memory consumption increases
Solution Approach 1:
The patent divides the photographing images into multiple groups and performs stitching processing on each group sequentially rather than loading all images simultaneously. This segmentation allows high-quality stitching to be achieved while maintaining limited memory usage, as only a subset of images needs to be in memory at any given time.
Solution Approach 2:
The patent performs preliminary actions by pre-processing and preparing image groups before the actual stitching operation. Images are organized into groups in advance, and memory is pre-allocated for processing each group sequentially, which optimizes both stitching quality and memory efficiency during the actual processing phase.
2Quantity of substance
If memory is dynamically managed by loading only output images, then memory efficiency is improved, but processing complexity increases
Solution Approach 1:
The patent implements dynamic memory management where the memory allocation and image loading strategy adapts based on the current processing stage and requirements. The system dynamically loads image groups into memory when needed and unloads them after processing, creating a flexible memory usage pattern that balances efficiency and complexity.
Solution Approach 2:
The patent introduces an intermediary memory management layer that coordinates between the image processing units and the physical memory resources. This intermediary structure handles the complexity of dynamic loading and unloading operations, simplifying the overall system architecture while maintaining memory efficiency.
3Manufacturing precision
If high resolution images are processed, then image quality is improved, but processing time increases
Solution Approach 1:
The patent segments the high-resolution image processing task into smaller sub-tasks that operate on divided image groups. By processing images in segments rather than as a complete set, the system maintains high image quality through detailed processing while reducing overall processing time through parallelizable smaller operations and efficient memory access patterns.
