Wide Viewing Angle Image Processing via 3D Projection Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing methods require significant computational resources and time to correct distortion and stabilize images, especially for wide viewing angle images, as they need to be preprocessed before display, which is inefficient and burdensome.
Innovation Solution
An apparatus and method that generates correction parameters for camera intrinsic and stabilization parameters to encode and decode projection geometry in real-time, allowing for three-dimensional rendering and correction of lens distortion and camera stabilization during image display, reducing processing burdens by transforming and projecting geometry in a virtual space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image distortion correction and camera stabilization are performed before display using conventional methods, then the image quality is improved, but the processing time and computational burden increase significantly
Solution Approach 1:
The patent transforms the image correction problem from 2D image space operations to 3D projection geometry operations. By representing the image as a projection of 3D geometry onto a 2D plane, corrections can be performed by adjusting projection parameters rather than processing pixel data, significantly reducing computational complexity and processing time while maintaining correction accuracy
Solution Approach 2:
The patent changes the approach from direct pixel manipulation to parameter-based correction. By modifying projection geometry parameters (such as projection matrix elements, camera intrinsic parameters) rather than processing image pixels directly, the system achieves the same correction effect with much lower computational burden, enabling real-time processing
2Manufacturing precision
If pre-processing is performed on wide viewing angle images before display, then distortion correction is achieved, but the computational resources and processing time required increase significantly
Solution Approach 1:
The patent moves the correction operation from 2D image space to 3D projection space. By representing the wide viewing angle image as a projection of 3D geometry and performing corrections by adjusting projection parameters in 3D space, the system achieves accurate distortion correction with significantly reduced computational resource requirements compared to traditional 2D image processing methods
Solution Approach 2:
The patent creates and manipulates a geometric model (projection geometry) that represents the image structure, rather than directly processing the actual image data. This geometric copy allows for efficient parameter-based corrections to be performed on the model, which then automatically applies to the rendered image, reducing the computational burden of direct image manipulation
3Stability of the object's composition
If conventional image processing methods are used for camera stabilization, then stabilization effect is achieved, but the processing complexity and time consumption increase
Solution Approach 1:
The patent achieves camera stabilization by adjusting projection geometry parameters rather than processing image sequences. By modifying the projection matrix and camera intrinsic parameters to compensate for camera movement, the system achieves stabilization effects with simpler processing logic and reduced computational complexity compared to traditional frame-by-frame image processing methods
