Surrounding Display Guide Line Transparency for Obstacle Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle surrounding display systems face issues with visibility and recognition of obstacles due to changes in display modes of guide lines, which can impair the perception of surrounding images and vehicle width or distance to obstacles.
Innovation Solution
A surrounding display device with a display processing unit that superimposes a guide line on a surrounding image, a detection unit that detects obstacles within the guide line region, and a change unit that reduces the salience of the guide line by increasing its transmittance when an obstacle is detected, ensuring clear visibility of both the guide line and the obstacle.

Engineering Contradiction Analysis
1Reliability
If the guide line display mode is changed to improve obstacle detection, then the visibility of the surrounding image is impaired
Solution Approach 1:
The guide line is divided into multiple sections along its length, with each section independently adjusted for transparency based on obstacle proximity. Sections closer to detected obstacles use higher transparency to maintain surrounding image visibility, while sections farther away maintain lower transparency for better guide line visibility.
Solution Approach 2:
The guide line display dynamically adjusts its transparency and visual properties in real-time based on detected obstacle positions and distances. When obstacles are detected, the system modifies the guide line appearance; when no obstacles are present, the guide line returns to its original high-visibility state.
2Illumination intensity
If the guide line salience is increased to improve visibility, then the recognition of vehicle width or distance to obstacle becomes difficult
Solution Approach 1:
Different portions of the guide line exhibit different transparency levels tailored to their functional needs. The guide line maintains high salience in regions where it serves as a reference for vehicle width, while becoming more transparent in regions where obstacle detection and distance measurement are priorities.

AI summary
A surrounding display device includes: a display processing unit that causes a display device to display a display image in which a guide line is superimposed on a surrounding image indicating a situation in surroundings of a mobile body; a detection unit that detects existence of an obstacle in a region specified by the guide line; and a change unit that changes a display mode of the guide line such that a salience of the guide line decreases when the detection unit detects the existence of the obstacle in the region.
