UAV Panoramic 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 display direction and angle, using panoramic video stabilization and user-controlled display settings to maintain a stable viewing experience regardless of flight direction changes.
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, then the viewing angle is fixed and simple to implement, but the video object visibility is lost when the UAV changes flight direction
Solution Approach 1:
The patent segments the coupling between flight direction and viewing angle by introducing an independent viewing angle control system. The UAV's flight control and camera viewing angle control are separated into independent modules, allowing the camera to maintain a fixed viewing angle relative to the ground while the UAV changes flight direction. This segmentation enables video object continuity without requiring complex mechanical adjustments to the camera mounting.
Solution Approach 2:
The patent replaces mechanical camera orientation adjustments with computational image processing and rendering techniques. Instead of physically rotating the camera to track objects, the system uses software-based methods to maintain video object visibility, substituting mechanical complexity with digital processing capabilities.
2Ease of operation
If the UAV adjusts flight direction to maintain video object visibility, then object tracking is achieved, but the viewing experience is disrupted and operation becomes complex
Solution Approach 1:
The patent establishes a predetermined relationship between UAV attitude changes and viewing angle adjustments. When the UAV changes flight direction, the system pre-calculates and automatically adjusts the viewing angle according to the established relationship, maintaining video object visibility without requiring real-time complex operations from the user. This preliminary setup of control relationships simplifies operation while maintaining viewing stability.
3Adaptability or versatility
If panoramic video is used to provide multi-angle viewing, then viewing versatility is improved, but video stabilization and processing complexity increase
Solution Approach 1:
The patent extracts and processes only the necessary portion of panoramic video data corresponding to the current viewing angle. Instead of transmitting or processing the entire panoramic video sphere, the system identifies and extracts the relevant angular sector based on UAV attitude and display requirements, reducing processing complexity while maintaining viewing flexibility.
Solution Approach 2:
The patent applies partial processing to panoramic video by rendering only the visible portion of the panoramic sphere at any given moment. This partial action approach processes less data than full panoramic rendering would require, reducing computational complexity while providing the same viewing experience for the user.
