UAV Escape Control Using Participant Position and Venue Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) used for providing information at competitions or events often interfere with participants, risking collision or distraction due to their flight paths and noise, particularly in sports like golf where precise concentration is required.
Innovation Solution
An unmanned aerial vehicle escape system that includes participant position information acquisition, movement instruction, layout information acquisition, escape destination determination, and escape mechanisms to safely reposition the UAV based on participant and venue data, avoiding interference zones and ensuring smooth event progression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the unmanned aerial vehicle stays at the same place to provide information, then the information provision function is maintained, but the participant may be interfered with by the UAV
Solution Approach 1:
The UAV dynamically adjusts its position between a stationary information-providing state and an escaping state. The system transitions from a fixed position to a moving position based on real-time detection of participant states, resolving the contradiction by making the position dynamic rather than static
Solution Approach 2:
The system uses feedback from participant position information and state detection to control UAV behavior. When the participant is detected to be in a concentration state, the UAV escapes; otherwise, it maintains its information provision position, creating a closed-loop control system that balances both requirements
2Measurement precision
If the unmanned aerial vehicle moves closer to photograph the participant, then the image quality improves, but the participant concentration deteriorates due to propeller noise and distraction
Solution Approach 1:
The system takes preliminary action by detecting participant concentration states before capturing images. When concentration is detected, the UAV escapes in advance to avoid causing distraction, preventing the harmful effect before it can occur
Solution Approach 2:
The UAV dynamically adjusts its distance from the participant based on real-time state detection. It moves closer for better imaging when the participant is not concentrating, and moves away when concentration is detected, optimizing both image quality and participant focus
3Duration of action of stationary object
If the unmanned aerial vehicle follows the flight path, then the information provision is continuous, but the collision risk with flying objects increases
Solution Approach 1:
The system performs preliminary detection of participant states and flight conditions before the UAV follows its flight path. By detecting potential collision risks in advance and escaping when concentration states are detected, it prevents collisions while maintaining continuous operation
Solution Approach 2:
The system continuously monitors participant position and state, providing feedback that controls UAV flight path execution. This closed-loop control allows the UAV to maintain continuous information provision while dynamically avoiding collision risks

AI summary
To avoid interfering with a participant when information on a venue of a competition or an event is provided by using an unmanned aerial vehicle, participant position information acquisition means of an unmanned aerial vehicle escape system acquires participant position information on a position of the participant in the venue of the competition or the event. Movement instruction means instructs an unmanned aerial vehicle for providing information on the venue to move to a position defined based on the participant position information. Layout information acquisition means acquires layout information on a layout of the venue. Escape destination determination means determines an escape destination of the unmanned aerial vehicle based on the participant position information and the layout information. Escape means causes the unmanned aerial vehicle to escape to the escape destination determined by the escape destination determination means.
