Dynamic Background Sky Display for 3D Navigation Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems fail to provide users with more graphical map data by displaying the same background images when the driving direction of a vehicle changes, despite the vehicle's location remaining unchanged.
Innovation Solution
A method and apparatus that store and maintain map data and background sky image data in a database, detect the driving direction angle of a vehicle, compute the corresponding background sky image position, extract the relevant image data, and display it as a background sky, allowing for a different background sky to be displayed based on the vehicle's direction in a 3D navigation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same background image is displayed when vehicle location does not change, then the navigation system maintains simple display logic, but the user experience becomes less graphical and less engaging
Solution Approach 1:
The background sky image is dynamically selected and displayed based on the vehicle's driving direction angle. The system continuously updates the background image to match the current driving direction, transforming the static display into a dynamic one that adapts to vehicle orientation changes, thereby improving display adaptability without requiring complex hardware modifications
Solution Approach 2:
The system changes the display parameter from a fixed background image to a direction-dependent background image. By using the driving direction angle as a variable parameter, the system selects appropriate background sky images from multiple pre-stored options, enabling the display to adapt to different driving directions while maintaining manageable system complexity through parameter-based selection
2Loss of information
If different background skies are displayed according to driving direction angle, then the graphical quality and user experience are improved, but the system requires storing and processing multiple background image datasets
Solution Approach 1:
The background sky image data is segmented into multiple directional segments, each corresponding to a specific driving direction angle range. Instead of storing and processing one large comprehensive image set, the system divides the sky imagery into manageable directional portions, allowing efficient storage and quick retrieval based on the current driving direction, thus reducing the effective data volume needed at any given time
Solution Approach 2:
The system applies local quality by storing and displaying background sky images with high visual fidelity only for the current driving direction, while other directional images are stored in a compressed or lower-resolution format. This ensures that the visual information quality is maintained for the relevant view while reducing the overall data storage requirements for all possible directions

AI summary
A method of displaying a background sky in a navigation system, the method including: storing and maintaining map data and background sky image data with respect to one or more directions of the map data in a database; detecting a driving direction angle of a vehicle; computing a position of a background sky image corresponding to the detected driving direction angle; extracting background sky image data corresponding to the computed position of the background sky image from the database; and displaying the extracted background sky image data as a background sky with respect to the map data.
