Windshield Navigation Image Composition for Misregistration Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems cause user discomfort due to misregistration and complexity in overlaying navigation guidance and map information, leading to potential misinterpretation and distraction for vehicle drivers.
Innovation Solution
An image generation apparatus that integrates vehicle position and path information to generate composite images of guide and map images, associating them through auxiliary images, allowing for natural interpretation and reducing user discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If navigation guidance and map information are overlaid on the windshield, then the driver can see driving-related images without large eye movements, but the user is likely to feel discomfort due to misregistration and complexity
Solution Approach 1:
The patent divides the navigation information into separate layers: guide image layer and map image layer. Each layer can be independently controlled and adjusted. The guide image layer contains directional guidance elements while the map image layer contains geographical context, allowing them to be processed and displayed separately to reduce complexity
Solution Approach 2:
The patent introduces an image generation apparatus as an intermediary component that processes and integrates the guide and map images before displaying them on the windshield. This intermediary device handles the complex tasks of image generation, alignment, and overlay, separating the complexity from the driver's direct interaction with the display
2Loss of information
If multiple navigation information elements are displayed together, then comprehensive navigation data is provided, but misregistration and complexity lead to potential misinterpretation and distraction
Solution Approach 1:
The patent utilizes the spatial dimension of the windshield display to organize navigation information. By projecting images at different positions and angles on the windshield, the system creates a three-dimensional spatial arrangement of navigation elements, allowing comprehensive information display while maintaining clear visual separation and reducing misinterpretation
Solution Approach 2:
The system incorporates feedback mechanisms where the image generation apparatus continuously adjusts the guide and map images based on vehicle position data and driver behavior. This feedback loop ensures accurate registration of overlay elements and adapts the display to reduce distraction, maintaining reliability while providing comprehensive navigation information

AI summary
An image generation apparatus (vehicle information acquirer/controller) is utilized in a display system that projects an image onto a display medium of a vehicle to enable a user to visually recognize a virtual image, and includes a vehicle information acquirer that acquires vehicle position information indicating the current location of a vehicle and path information indicating a path along which the vehicle is guided to a destination; a map image generator that generates a map image of the vicinity of the current location in accordance with the vehicle position information; a guide image generator that generates a guide image indicating a path relative to the current location in accordance with the vehicle position information and the path information; and a composite image generator that generates a composite image for projecting the guide image and the map image, in a mode in which these images are associated with each other.
