Vehicle Display Control for Distorted Wheel Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for vehicles produce unnatural bird's-eye view images when the vehicle is steered significantly, causing wheel images to appear distorted and protruding, leading to discomfort for viewers.
Innovation Solution
A display control device with a viewpoint conversion unit, steering determination unit, image correction unit, and display control unit that suppresses or makes inconspicuous the image of the wheel in bird's-eye view images when the steering angle exceeds a predetermined value by creating a masked area and replacing it with a history or replacement image, preventing distortion and positional shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If viewpoint conversion is performed on images captured by cameras mounted on the vehicle to create bird's-eye view images, then the synthesized image provides comprehensive surrounding view information, but wheel images become distorted and protruding when the vehicle is steered largely
Solution Approach 1:
The system performs preliminary detection of wheel positions and steering angles before synthesizing the bird's-eye view image. When large steering angles are detected, the system pre-adjusts the image synthesis process to suppress or mask distorted wheel images before they appear in the final displayed image, preventing the unnatural protruding effect
Solution Approach 2:
The system applies different processing quality to different regions of the bird's-eye view image. Specifically, regions containing wheel images that are detected to be distorted due to large steering angles receive special processing (suppression or masking), while other regions maintain normal image quality and detail
2Shape
If the steering angle exceeds a predetermined value, then the wheel image appears distorted and protruding in the bird's-eye view, but suppressing or masking the wheel image creates a masked area that may reveal underlying unnatural images
Solution Approach 1:
The system introduces a background image as an intermediary layer behind the wheel image. When the wheel image needs to be suppressed or masked due to distortion, the background image (which contains the road surface and surrounding environment) is displayed instead, providing a natural transition that avoids revealing unnatural underlying images and maintains visual continuity in the bird's-eye view

AI summary
In a display control device, a viewpoint conversion unit converts the viewpoint of images captured by cameras to obtain viewpoint converted images as viewed from above the own vehicle. A steering determination unit determines whether the steering angle of a wheel of the own vehicle is equal to or greater than a predetermined value. When the steering angle is equal to or greater than the predetermined value, an image correction unit creates a corrected image by processing a viewpoint converted image of the wheel in the viewpoint converted image so that the image of the wheel is prevented from being displayed. The image synthesis unit combines the corrected image and the other viewpoint converted images to create a synthesized image. The display control unit displays the synthesized image and an image of the own vehicle on a display device.
