3D Composite Outside-View Display for Eye Position Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices fail to intuitively convey the relationship between the outside image displayed on a screen and the eye position of the occupant, making it difficult for the occupant to adjust their view to see the desired outside image.
Innovation Solution
An image processing device that includes an eye position information acquisition unit, an image acquisition unit, a cropping unit, a projection image generation unit, and an image compositing unit to generate a composite image that aligns the outside image with the eye position, allowing intuitive understanding of the relationship between the screen display and the eye position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a flat screen displays an outside image, then the image can be shown on the screen, but the occupant cannot intuitively understand the relationship between eye position and the displayed image
Solution Approach 1:
A projection image representing a 3D model with an opening is introduced as an intermediary between the flat displayed image and the occupant's eye position. This projection image provides depth cues and spatial context, enabling the occupant to intuitively understand the relationship between their eye position and the displayed outside image without requiring complex adjustments.
2Illumination intensity
If the installation region of the display device is transparent, then the outside can be visible, but the image appears flat and lacks spatial context
Solution Approach 1:
The projection image incorporates a 3D model with an opening that simulates curved or three-dimensional spatial geometry. This curved/spheroidal representation is superimposed on the transparent display region, adding spatial context and depth perception to the otherwise flat displayed image, allowing the outside to remain visible while providing intuitive spatial relationships.

AI summary
An image processing device that enables an occupant of a mobile body, such as a vehicle, to intuitively understand the relationship between an outside image displayed on a display device and an eye position. The device includes: a 3D position information acquisition unit that acquires information on the position of an occupant's eye; an image acquisition unit that acquires an outside image; a cropping unit that crops a region image from the outside image, based on the eye position information; a projection image generation unit that generates a projection image of a 3D model having an opening, as viewed from the position of the eye; an image compositing unit that composites the region image and the projection image such that the region image appears in the opening of the projection image on the screen; and an image output unit that outputs a composite image to the display device.
