3D Vehicle Surround View Icon Stretching for Positional Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle surrounding environment display devices struggle to accurately convey the positional relationship between the host vehicle and surrounding objects, leading to user discomfort when viewing the virtual space.
Innovation Solution
A vehicle surrounding environment display device that adjusts the length of a three-dimensional host vehicle icon based on the virtual viewpoint's position relative to a predefined icon transformation region, stretching the icon when the viewpoint is within this region to enhance spatial perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual space is generated to display the surrounding environment of the host vehicle, then the user can freely view the environment around the vehicle, but it becomes difficult to grasp the positional relationship between the host vehicle and surrounding objects compared to the actual environment
Solution Approach 1:
The patent introduces a transformation region in the virtual space that corresponds to the blind spot region of the host vehicle. When the virtual viewpoint enters this transformation region, the viewpoint position is transformed to prevent it from entering the blind spot region, thereby maintaining accurate positional relationship representation while allowing free viewing in other dimensions.
Solution Approach 2:
The patent dynamically adjusts the virtual viewpoint position based on its coordinates relative to the transformation region. When the viewpoint approaches the transformation region, its position parameters are modified to maintain accurate spatial relationships, while other parameters remain unchanged to preserve viewing freedom.
2Ease of operation
If the virtual viewpoint is allowed to move freely in the virtual space, then the user can view the environment from any angle, but the user experiences discomfort in recognizing the surrounding environment due to distorted positional relationships
Solution Approach 1:
The patent implements dynamic adjustment of the virtual viewpoint position based on its real-time coordinates. When the viewpoint enters the transformation region corresponding to the blind spot, its position is dynamically transformed to maintain accurate spatial relationships, while allowing free movement in non-transformed regions.
Solution Approach 2:
The transformation region acts as an intermediary between the user's free viewpoint movement and the accurate representation of spatial relationships. It mediates by transforming viewpoint positions that would otherwise create distortion, while leaving other positions unchanged.

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 displayed in a stretching display that is stretched in length of the host vehicle icon compared to when the virtual viewpoint is not located in the icon transformation region.
