Ship AR Display Dynamic Label Positioning to Prevent Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image generation devices for ships struggle to effectively display various kinds of information about targets around the ship in a way that prevents overlap and ensures readability.
Innovation Solution
An image generation device and method that utilize augmented reality (AR) to overlay detailed information onto an image captured by a camera on a ship, using a combination of sensors and ship devices to provide real-time data and adjust the display dynamically to prevent overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text labels are repositioned to prevent overlap, then readability is improved, but the complexity of the display system increases
Solution Approach 1:
The text labels are dynamically repositioned based on the relative positions of targets and the ship's orientation. The display controller continuously adjusts label positions according to target distance, direction, and ship attitude angles, making the system adaptive rather than static to prevent overlap while maintaining readability
Solution Approach 2:
The system changes multiple parameters simultaneously including label position coordinates, font size, and placement orientation based on target distance and direction. By adjusting these parameters dynamically, the system prevents label overlap and ensures readability without requiring complex additional hardware
2Adaptability or versatility
If multiple kinds of information are displayed about targets, then the usefulness for navigation is improved, but the likelihood of information overlap increases
Solution Approach 1:
Multiple types of information (target distance, direction, ship attitude, AIS data) are segmented and displayed as separate text labels rather than combining them into a single crowded display element. Each piece of information is individually positioned and managed to prevent overlap while maintaining comprehensive navigation data
Solution Approach 2:
The system utilizes multiple spatial dimensions for label placement including horizontal position, vertical position, and orientation angles. By distributing information across these dimensions and adjusting label orientation according to ship attitude, the system accommodates multiple information types without overlap
3Loss of information
If text labels are displayed close to targets, then the correlation between target and information is improved, but the risk of overlap with other labels increases
Solution Approach 1:
Each text label is given local quality characteristics including individual position, orientation, and size adjustments based on its specific target's properties. Labels closer to targets have optimized positioning to ensure clear association, while the system dynamically adjusts each label's parameters to prevent overlap with neighboring labels

AI summary
An image generation device (1) includes a camera (3) installed on a ship (4), a ship device which acquires target information about a target, an AR image generation unit (20) which generates an AR image in which the target information acquired by the ship device is displayed in a captured image captured by the camera (3), marker display means for displaying a marker for selecting the target by a user such that the marker moves according to a display place of the target in the AR image, and marker moving means for moving the display place of at least one of the markers so that determination regions which determining that each marker has been selected do not overlap each other.
