3D Vehicle Surround View Icon Morphing for Positional Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle surrounding environment display devices struggle to accurately convey the positional relationship between the vehicle and surrounding objects, leading to a sense of incongruity in the user's perception of the virtual space compared to the real environment.
Innovation Solution
A vehicle surrounding environment display device that transforms the host vehicle icon in a virtual space based on the location of the virtual viewpoint relative to a predefined icon transformation region, adjusting the width or height of the icon to align with the user's perspective, thereby correcting the perceived positional relationship.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual space is generated and displayed with a virtual viewpoint, then the user can freely view the environment around the vehicle, but it becomes difficult to understand the positional relationship between the vehicle and surrounding objects compared to the real environment
Solution Approach 1:
The patent transforms the host vehicle icon by changing its geometric parameters (width and height) based on the virtual viewpoint position. When the viewpoint is in the icon transformation region, the icon's width is narrowed and height is reduced to correct the distorted positional perception, thereby resolving the contradiction between viewing freedom and positional accuracy
2Ease of operation
If the virtual viewpoint is allowed to move freely in the virtual space, then the user can view the surrounding environment from multiple angles, but a sense of incongruity arises in the user's perception of the surrounding environment
Solution Approach 1:
The patent defines an icon transformation region around the host vehicle icon and applies transformation only when the virtual viewpoint is located within this region. This localized approach maintains viewing freedom while correcting perception incongruity only where necessary, preserving reliability without restricting ease of operation

AI summary
A vehicle surrounding environment display device configured to generate a virtual space corresponding to a surrounding environment of a host vehicle on the basis of detection information from an external sensor of the host vehicle and display an image inside the virtual space viewed from a virtual viewpoint operated by a user of the host vehicle on a display, wherein a three-dimensional host vehicle icon corresponding to the host vehicle is disposed in the virtual space, and when the virtual viewpoint is located in an icon transformation region set above the rear or front of the host vehicle icon, the host vehicle icon is transformed so that a width of an upper surface of the host vehicle icon is narrower as compared to when the virtual viewpoint is not located in the icon transformation region.
