UAV Map Display Logic for Head-On Collision Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to consider the traveling direction of unmanned aerial vehicles when determining the need to display cautionary marks, leading to unnecessary notifications of potential near misses or collisions.
Innovation Solution
An information processing device and method that acquires position and direction information of multiple UAVs, displaying cautionary information only when the distance and front directions of two or more UAVs meet specific thresholds, indicating a higher risk of collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monitoring required marks are displayed based only on distance between aircrafts, then all close aircraft pairs are notified, but unnecessary notifications occur when aircraft are not facing each other
Solution Approach 1:
The patent applies local quality by making the monitoring mark display conditional on the specific spatial relationship between aircraft. Instead of uniformly displaying marks for all aircraft pairs within distance threshold, the system selectively displays marks only when aircraft are facing each other (head-on or near head-on configuration), thereby reducing false positives while maintaining reliability for actual collision risks
Solution Approach 2:
The system dynamically evaluates the relative orientation and facing direction of aircraft in addition to distance. The monitoring mark display is not static but depends on real-time assessment of whether aircraft are facing each other, allowing the system to adapt notifications to the actual collision risk situation
2Ease of operation
If monitoring required marks are displayed for all aircraft pairs within threshold distance, then comprehensive monitoring is achieved, but operator attention is wasted on low-risk situations
Solution Approach 1:
The patent makes the monitoring function selective by applying different display behaviors to different spatial configurations. Aircraft pairs that are close but not facing each other do not trigger monitoring marks, while those facing each other do, thereby optimizing operator attention allocation to high-risk situations only

AI summary
An UAV monitoring server acquires position information indicating a position and direction information indicating a front direction of each of a plurality of UAVs in flight, and in a case where the plurality of UAVs includes two or more UAVs in which a distance between the positions is less than or equal to a predetermined first threshold value and the front directions are facing each other, causes information urging caution to be displayed in association with respective UAV objects of the two or more UAVs on a two-dimensional map screen.
