Vehicle Peripheral Display Device Indicator Line 3D Shadow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle peripheral display devices struggle to clearly depict indicator lines on a three-dimensional peripheral image, making it difficult for drivers to recognize their positional relationship with the image, especially distinguishing between road lines and indicator lines.
Innovation Solution
The integration of a shadow portion and/or a side surface portion adjacent to the indicator lines enhances their three-dimensional display, creating a visual effect that makes the lines appear as if they are on the road surface, improving recognition for both color-blind and non-color-blind drivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If indicator lines are displayed two-dimensionally on a peripheral image, then the display device can show guidance information, but the positional relationship between the indicator lines and the three-dimensional peripheral image is difficult to recognize
Solution Approach 1:
The patent applies dimensionality change by adding a shadow portion to the two-dimensional indicator line, creating a three-dimensional visual effect. The shadow portion extends from the indicator line in the direction opposite to the light source, giving the line depth and making it appear to float above or be embedded in the road surface. This resolves the contradiction by enhancing positional relationship recognition through 3D visualization without adding physical complexity to the display device.
Solution Approach 2:
The patent utilizes color changes by displaying the shadow portion in a different luminance or color tone compared to the indicator line itself. The shadow is typically rendered in a darker shade to simulate lighting effects, creating visual contrast that enhances the perception of depth and spatial relationship between the indicator line and the road surface in the peripheral image.
2Reliability
If indicator lines are displayed with uniform thickness, then the display is simple, but the lines are difficult to distinguish from road lines in the peripheral image
Solution Approach 1:
By adding the shadow portion to the indicator line, the patent creates a three-dimensional visual effect that distinguishes the indicator line from flat road markings. The shadow gives the indicator line apparent height or depth, making it stand out from the two-dimensional road surface and lines, thereby improving distinguishability without complicating the display device.
Solution Approach 2:
The patent enhances line distinguishability by rendering the shadow portion in a different color or luminance level than the indicator line. This color contrast creates visual separation between the indicator line and the road surface, making it easier for drivers to distinguish the guidance information from actual road markings.

AI summary
The device is provided with an image acquisition unit for acquiring a peripheral image of a vehicle, the peripheral image being captured by an image pickup device provided to the vehicle; a display device for displaying the peripheral image, the display device being provided inside a vehicle cabin; and an indicator line output unit for causing an indicator line as a guide for a driver during a driving operation to be displayed superimposed on the peripheral image, at least one of a shadow portion and a side surface portion adjacent to the indicator line being added to the indicator line.
