Vehicle Display System Target Position Distortion Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems struggle to reliably identify the intended target for messages displayed on the outer surface of a vehicle, making it difficult to ensure that the message is viewed by the correct person.
Innovation Solution
A vehicle display system that includes a display device, a position acquiring unit to determine the target's position, and a distortion correction processor to correct the image displayed based on the target's position, ensuring the intended person can view the image clearly while others perceive it as distorted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If messages are displayed on the outer surface of the vehicle for persons around the vehicle, then communication with external persons is improved, but it becomes difficult to reliably identify the intended target and ensure clear viewing
Solution Approach 1:
The patent applies distortion correction to create location-specific image qualities. By calculating distortion based on the intended target's position and applying opposite distortion to the display image, the system ensures that only the intended target views the message clearly, while other positions perceive distorted images. This local quality differentiation enables reliable target identification and maintains communication effectiveness.
2Measurement precision
If display is optimized for a specific target position, then viewing clarity for the intended target is improved, but viewing quality for other positions deteriorates
Solution Approach 1:
The patent converts the harmful effect of distortion into a beneficial identification mechanism. By intentionally introducing position-specific distortion correction, the system makes the display clear only at the intended target's position while deliberately distorted at other positions. This transforms distortion from a defect into a useful feature for target identification and message delivery control.
3Manufacturing precision
If distortion correction is applied based on target position, then message delivery accuracy is improved, but system complexity increases
Solution Approach 1:
The patent performs preliminary distortion correction calculations based on predetermined display positions and target positions. By pre-calculating the distortion parameters and storing them in advance, the system reduces real-time processing complexity. The distortion correction is applied using pre-computed values, which simplifies the control process while maintaining high message delivery accuracy.

AI summary
A vehicle display system includes a display device, a position acquiring unit, and a distortion correction processor. The display device is mounted on a vehicle. The position acquiring unit is configured to acquire a position of a target by which an image to be displayed by the display device is to be viewed. The distortion correction processor is configured to correct, on a basis of the position of the target acquired by the position acquiring unit, distortion of the image to be displayed by the display device.
