Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft display systems face challenges in distinguishing and accurately rendering detached objects, such as power lines and bridges, within terrain data, which can lead to difficulties in providing a clear and effective visual representation for flight crews.
Innovation Solution
A method that involves receiving terrain data, generating a point cloud of a three-dimensional field of view, identifying detached objects, and generating display commands to emphasize these objects within the visual display, allowing for their accurate rendering on a display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional terrain data processing methods are used, then the display system can show basic terrain features, but detached objects such as power lines and bridges cannot be accurately distinguished and displayed
Solution Approach 1:
The patent segments terrain data processing into distinct stages: generating a point cloud from terrain data, identifying detached objects within the point cloud, and rendering them with appropriate visual differentiation. This segmentation allows the system to handle complex terrain data systematically while improving detection accuracy for detached objects.
Solution Approach 2:
The patent transforms traditional 2D terrain representation into a 3D point cloud structure, enabling the system to detect and display detached objects in three-dimensional space. This dimensional enhancement allows flight crews to perceive the spatial relationships and heights of detached objects relative to the terrain, significantly improving measurement precision.
2Manufacturing precision
If detailed terrain data is stored and processed, then a high level of detail can be achieved in synthetic displays, but storing and processing large amounts of terrain data becomes difficult
Solution Approach 1:
The patent extracts only the essential geometric information needed for display by converting detailed terrain data into a point cloud representation. This extraction process retains the necessary spatial information for accurate rendering while reducing the complexity of data storage and processing by eliminating redundant detailed information.
Solution Approach 2:
The patent creates a simplified digital copy of the terrain environment in the form of a point cloud, which preserves the essential spatial relationships and features needed for synthetic vision display. This copy enables high-precision rendering without requiring storage of the full complexity of original terrain data.
3Loss of information
If detached objects are not distinguished from attached objects, then the display system is simpler to operate, but flight crews lack situational awareness of detached objects
Solution Approach 1:
The patent applies local quality differentiation by rendering detached objects with distinct visual characteristics compared to attached terrain features. This allows flight crews to immediately distinguish between objects that are part of the terrain and those that are detached, preserving critical information while maintaining intuitive display operation through consistent visual cues.

AI summary
A display system is provided for a vehicle. The display system includes a data source configured to provide terrain data with detached objects that are detached from ground terrain and attached objects that are attached to ground terrain; a processing unit coupled to the data source configured to receive the terrain data and to distinguish the detached objects from the attached objects to generate display commands for a three-dimensional view that comprises graphical elements representing both the detached objects and the attached objects; and a display device coupled to the processing unit and configured to receive the display commands and operable to render the common three-dimensional view to thereby allow viewing of the detached objects and the attached objects.
