Vehicle Image Controller Gaze Tracking Distortion Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle imaging devices have limited angle of view and suffer from increased distortion when attempting to expand this view, restricting user freedom and requiring precise camera placement, which is challenging due to design constraints.
Innovation Solution
A vehicle image controller that determines and responds to user head or gaze motion by shifting the camera view point and correcting distortion, using a processor to extract and filter image data based on face and gaze information, and applying correction filters to wide-angle images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the angle of view of a camera is increased to expand the visible area, then the view area is improved, but image distortion is increased
Solution Approach 1:
The patent applies distortion correction processing to transform wide-angle images captured by cameras with large angle of view. The processor corrects the distorted regions by applying geometric transformation parameters, thereby maintaining both a wide view area and acceptable image quality without requiring precise camera placement.
2Area of stationary object
If the angle of view of a camera is indefinitely increased, then the view area is improved, but there is an uppermost limit due to excessive distortion
Solution Approach 1:
The system uses distortion correction processing with adjustable parameters to compensate for the inherent limitations of wide-angle lenses. By applying correction algorithms, the system can utilize cameras with very wide angle of view while maintaining reliable image quality, effectively removing the uppermost limit on view area expansion.
3Manufacturing precision
If distortion correction is applied to wide-angle images, then image quality is improved, but processing complexity is increased
Solution Approach 1:
The patent pre-stores distortion correction information corresponding to different camera positions and viewing angles. When an image is captured, the processor quickly retrieves the appropriate correction parameters from storage and applies them, avoiding the need for complex real-time distortion calculation and reducing processing complexity while maintaining image quality.
4Area of stationary object
If multiple cameras are installed to expand the view area without distortion, then view area is improved, but device complexity and installation difficulty are increased
Solution Approach 1:
The patent combines images from multiple cameras into a single synthesized view that provides a wide field of view without the need for complex multi-camera systems. The processor merges the captured images and applies distortion correction to create a unified wide-angle display, reducing the number of cameras needed and simplifying the overall system complexity.
