Variable Compression Panorama Display for Aircraft Cockpits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cockpit display systems provide a limited field of view, restricting pilots' ability to monitor the entire airspace, as they only show a narrow angular range in front of the aircraft, which is insufficient for operational tasks.
Innovation Solution
An environment display device with an image signal processing system that allows for variable compression of panoramic images, enabling undistorted or compressed areas to be selected, with adjustable viewing angles between 0° and 360° horizontally and -90° to +90° vertically, allowing for enhanced field of view without distortion impairment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a panoramic image with large field of view is displayed on the image display device, then the operator's field of view is expanded, but image distortion occurs that impairs the operator's ability to perceive the situation
Solution Approach 1:
The panoramic image is divided into multiple compression areas with different compression degrees. The image display device displays at least a first compression area with a first degree of compression and a second compression area with a second degree of compression, where the compression degrees differ. This segmentation allows different regions to be displayed with appropriate distortion levels, maintaining situational awareness while reducing peripheral distortion.
Solution Approach 2:
Different regions of the panoramic image are assigned different compression characteristics. The image signal processing device processes input image signals to create output image signals where at least a first area is reproduced with a first degree of compression and a second area with a second degree of compression. This local quality approach ensures that critical areas maintain higher fidelity while peripheral areas accept greater compression.
2Area of moving object
If the entire panoramic image is displayed with uniform compression, then the field of view is maximized, but the resolution and detail are reduced across all areas
Solution Approach 1:
The patent applies different compression degrees to different regions of the panoramic image. The image signal processing device creates output image signals where at least a first area is reproduced with a first degree of compression and a second area with a second degree of compression. This allows critical areas to maintain higher resolution while peripheral areas use greater compression to maximize field of view.
Solution Approach 2:
The panoramic image is segmented into multiple compression areas. The image display device displays at least a first compression area with a first degree of compression and a second compression area with a second degree of compression. This segmentation enables optimized resolution distribution across the field of view.
3Area of moving object
If variable compression is applied to different areas of the panorama, then the field of view is enhanced without excessive distortion, but the device complexity increases
Solution Approach 1:
The image signal processing device dynamically adjusts compression parameters based on the spatial location and characteristics of different image areas. The system can adaptively determine compression degrees for different regions, allowing flexible optimization of field of view and distortion control. This dynamic approach enables the system to respond to varying operational requirements.
Solution Approach 2:
The patent changes compression parameters spatially across the image. The image signal processing device processes input image signals to create output image signals with varying compression degrees in different areas. This parameter change approach allows optimization of both field of view and image quality without requiring complete system redesign.
