UAV Video Display With Independent Viewing-Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAV surveillance and aerial photography systems limit viewers to a specific viewing angle and require complex flight adjustments to maintain video object visibility, complicating the viewing experience.
Innovation Solution
The flight direction of the UAV is decoupled from the display viewing angle, allowing independent control of video viewing angles through inertial and positional data, enabling spherical, annular, or wide-angle video display without altering the UAV's flight path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera head is mounted in front of the UAV in the flight direction to capture video, then the UAV can obtain viewing experience based on its flight direction, but the viewers are limited to a specific viewing angle and require complex flight adjustments to maintain video object visibility
Solution Approach 1:
The patent segments the coupling between UAV flight direction and video display angle by introducing an independent angle control mechanism. The video display angle can be adjusted separately from the flight path, allowing viewers to change viewing angles without requiring flight adjustments. This decoupling resolves the contradiction by enabling viewing angle flexibility while maintaining simple flight operation.
Solution Approach 2:
The patent implements dynamic angle adjustment capability where the video display angle can be changed in real-time independently of the UAV's flight direction. This dynamic control allows the system to adapt to different viewing preferences without affecting the flight path, thus improving viewing angle flexibility while keeping flight operation simple.
2Adaptability or versatility
If the UAV flight direction is coupled with the video display angle, then the system structure is simple, but the viewing experience is limited and requires flight adjustments to maintain object visibility
Solution Approach 1:
The patent divides the control system into independent modules: flight control and angle display control. This segmentation allows the video display angle to be adjusted independently from the flight direction, achieving viewing angle independence without significantly increasing overall system complexity. The modular approach maintains structural simplicity while adding the desired flexibility.
Solution Approach 2:
The patent makes the control system multi-functional by enabling it to independently control both flight path and video display angle. This universal control capability allows a single system to handle both navigation and viewing angle adjustment, achieving viewing angle independence without proportionally increasing device complexity.
