Vehicle Overview Image Width Recognition via Planar Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image generation devices struggle to accurately display vehicle width in overview images, especially when the virtual viewpoint is positioned to view one side surface of the vehicle, making it difficult for drivers to recognize the vehicle's dimensions.
Innovation Solution
An image generation device synthesizes an overview image from multiple camera angles on the vehicle, superimposing a planar image of the vehicle onto the road surface, allowing both side surfaces to be displayed as independent lines, facilitating intuitive recognition of the vehicle's width and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a three-dimensional shape of the vehicle is superimposed on the overview image, then the vehicle position is displayed, but the vehicle width is difficult to recognize depending on the virtual viewpoint position
Solution Approach 1:
The patent transitions from displaying a three-dimensional vehicle shape to displaying a two-dimensional planar image of the vehicle superimposed on the overview image. This dimensional reduction allows the vehicle width to be clearly represented as a planar figure that can be intuitively recognized by the driver, eliminating the confusion caused by three-dimensional perspective effects in the overview image.
Solution Approach 2:
The patent creates a planar copy or representation of the vehicle (a two-dimensional figure representing the vehicle's outline) and superimposes it on the overview image. This copied planar representation accurately reflects the vehicle's width and position without the complications of three-dimensional perspective, making it easy for the driver to recognize the vehicle dimensions.
2Productivity
If the virtual viewpoint is positioned to view one side surface of the vehicle, then the overview image is generated, but the vehicle width recognition becomes difficult
Solution Approach 1:
Instead of relying on the three-dimensional viewpoint position to convey vehicle width information, the patent projects a two-dimensional planar representation of the vehicle onto the overview image. This planar figure clearly displays the vehicle's width regardless of the virtual viewpoint's position, maintaining overview image generation efficiency while improving width display accuracy.
Solution Approach 2:
The patent uses visual representation changes (creating a distinct planar figure) to highlight the vehicle's width. By representing the vehicle as a separate planar overlay with clear boundaries, the system makes the vehicle width visually distinct and easily recognizable against the background overview image, independent of viewpoint orientation.

AI summary
An image generation device according to an embodiment includes a synthesis unit and a superimposition unit. The synthesis unit synthesizes an overview image for a virtual viewpoint that is provided in a manner to look in a direction of travel of a vehicle so as to include at least a portion of a side of the vehicle based on a taken image that is taken by an image-taking unit that is provided on the vehicle. The superimposition unit superimposes a plane image where a vehicle has been caused to be planar, at a position of the vehicle on a road surface, on an overview image that is synthesized by the synthesis unit.
