Traveling-State Display Device for Vehicle Wobble Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safe driving education technologies fail to effectively visualize a vehicle's wobble state, such as deviation from a traveling lane or dangerous wobble, making it difficult for drivers to recognize steering-induced movements from onboard camera videos.
Innovation Solution
A traveling-state display device that detects a virtual central line from a road-captured image, transforms the image to stabilize the road surface, and moves a symbol indicating the vehicle to show its position, allowing for clear visualization of the vehicle's wobble state by combining transformed images with traveling trajectory and lane markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a road-captured image is displayed directly to show vehicle traveling state, then the actual driving state can be visualized, but the vehicle's wobble state and deviation from traveling lane cannot be clearly recognized
Solution Approach 1:
The patent introduces a virtual central line as an intermediary reference element that is superimposed on the road-captured image. This virtual central line serves as a mediator between the raw camera footage and the driver's perception, enabling the driver to visually recognize vehicle wobble state and lane deviation without altering the original road-captured image. The virtual central line acts as a visual reference that transforms the undifferentiated road view into an informative display showing vehicle position and movement trajectory relative to the lane center.
2Measurement precision
If the road-captured image is transformed to stabilize the road surface, then the visualization of vehicle wobble state is improved, but the processing complexity increases
Solution Approach 1:
The patent segments the image processing into distinct functional components: (1) detection of the virtual central line from the road-captured image, (2) calculation of vehicle position relative to the virtual central line, and (3) superimposition of the virtual central line and vehicle position symbol on the transformed image. This segmentation allows each processing step to be optimized independently, reducing overall processing complexity while maintaining measurement precision for vehicle position detection.
Solution Approach 2:
The patent creates a virtual copy of the central line position and vehicle trajectory information, superimposing these calculated elements over the transformed road-captured image. Instead of complexly transforming the entire original image to show vehicle movement, the system copies and overlays simplified visual representations (virtual central line and vehicle position symbol) that convey the essential wobble state information with minimal processing requirements.
3Loss of information
If a symbol indicating vehicle position is moved according to traveling position, then the movement trajectory is emphasized, but the device complexity increases
Solution Approach 1:
The patent extracts only the essential trajectory information needed to show vehicle wobble state - specifically the lateral position of the vehicle relative to the virtual central line - and displays this as a simplified moving symbol. Instead of processing and displaying complex trajectory data, the system extracts and displays only the critical position information, reducing display processing complexity while maintaining effective visualization of the traveling trajectory and wobble pattern.

AI summary
A computer detects a virtual central line of a traveling lane from a road-captured image captured from a vehicle. Next, the computer displays a transformed image generated by transforming the road-captured image such that the detected virtual central line is situated in a prescribed position. At this point, the computer moves a display position of a symbol indicating the vehicle on the generated transformed image according to a result of detecting a traveling position of the vehicle in the traveling lane.
