UAV Relative Position Display Using a Fixed Home Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of unmanned aerial vehicles (UAVs) experience disorientation during flight due to the UAV model deviating from a preset reference point, making it difficult to control the vehicle effectively.
Innovation Solution
A method and system that involves obtaining and displaying the relative location of the UAV in a terminal using a home point as a reference, allowing the UAV to be monitored and controlled more accurately by maintaining the home point as a central reference within the terminal display, even as the UAV moves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UAV model is displayed in the terminal without a fixed reference point, then the UAV can be tracked during flight, but the model deviates from the preset reference start point causing user disorientation
Solution Approach 1:
The patent introduces a virtual reference point (home point) as an intermediary element between the UAV and the user interface. This virtual reference point remains fixed on the terminal display while the UAV model moves relative to it, providing a stable reference that prevents user disorientation. The home point acts as a mediator that maintains the relationship between the moving UAV and the static display interface.
Solution Approach 2:
The patent transforms the display system from showing absolute position to showing relative position. Instead of displaying the UAV's absolute coordinates on the map, the system displays the UAV's position relative to the home point, creating a new dimensional reference frame centered on the home point. This dimensional transformation allows the reference point to remain fixed while the UAV model moves within this relative coordinate system.
2Measurement precision
If the terminal display shows the UAV's absolute position on the map, then the UAV location is accurately represented, but the home point moves and disappears from view when UAV flies beyond threshold
Solution Approach 1:
The patent inverts the traditional display approach by making the home point the center of the display coordinate system rather than making the map the reference. Instead of moving the home point with the UAV or keeping it fixed on the map, the system inverts the reference frame so that the home point remains fixed at the center of the terminal display while the UAV position is updated within this fixed reference frame. This inversion prevents the home point from disappearing.
3Ease of operation
If the reference point is updated to follow the UAV, then the UAV remains centered in the display, but the user loses the reference to the original start point
Solution Approach 1:
The patent extracts the reference function from the home point itself and separates it from the UAV's position. The home point is extracted as a fixed reference marker that remains at the original start location, while the UAV's position is displayed relative to this extracted reference point. This extraction allows the reference information to be maintained independently of the UAV's movement, preventing the loss of reference to the start point.
