UAV Panoramic Viewing Control for Independent Flight and Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAV surveillance and aerial photography systems are limited by the camera's viewing angle, requiring the vehicle to be manually maneuvered to re-observe objects outside its field of view, and the video display direction is fixed to the flight direction, leading to a poor user experience.
Innovation Solution
A control method and system that acquires and displays the UAV's attitude and video in a panoramic format, allowing independent control of flight direction and viewing angle, enabling smooth video viewing from any angle through spherical, annular, or wide-angle videos, processed for stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a camera head is mounted in front of the UAV in the flight direction, then the UAV can capture videos in the flight direction, but the viewing angle is limited and objects outside the field of view cannot be observed without manual maneuvering
Solution Approach 1:
The patent transitions from a single forward-facing camera to a multi-camera array arranged in different spatial dimensions around the UAV body. This includes cameras mounted on the front, rear, left, and right sides, enabling 360-degree panoramic video capture without requiring manual repositioning of the UAV. The dimensional arrangement of cameras resolves the contradiction by providing omnidirectional coverage while maintaining automated operation.
Solution Approach 2:
The patent implements a multi-functional camera system where multiple cameras serve different viewing directions simultaneously. The front camera captures forward views, rear cameras capture backward views, and side cameras capture lateral views. This universal camera array allows the UAV to observe objects from any direction without manual intervention, resolving the contradiction between ease of observation and viewing angle coverage.
2Ease of operation
If the video display direction is fixed to the flight direction, then the system is simple to implement, but the user experience is poor as users cannot view objects from different angles
Solution Approach 1:
The patent implements dynamic video synthesis that adapts to user viewing requirements. The system synthesizes panoramic videos from multiple camera feeds in real-time, allowing users to view objects from any angle by rotating the synthesized view rather than physically repositioning the UAV. This dynamic approach enhances user experience while managing system complexity through software-based solutions.
Solution Approach 2:
The patent creates virtual panoramic video copies from multiple physical camera feeds. Instead of requiring users to manually switch between different camera views or reposition the UAV, the system generates synthesized panoramic video representations that can be rotated and viewed from any angle. This copying approach improves user experience while avoiding the complexity of physical reconfiguration.
3Productivity
If manual maneuvering is required to re-observe objects outside the field of view, then the single camera system is simple, but time is lost and productivity decreases
Solution Approach 1:
The patent pre-positions multiple cameras to cover all directional views before observation begins. The camera array is configured in advance to capture front, rear, left, and right views simultaneously, eliminating the need for time-consuming manual repositioning during observation. This preliminary arrangement of cameras resolves the contradiction by enabling immediate access to any viewing angle.
Solution Approach 2:
The patent enables continuous panoramic video capture from all directions simultaneously through the multi-camera array. Unlike single-camera systems that require intermittent repositioning, this system maintains continuous observation capability across all angles, eliminating dead time and improving observation efficiency while reducing the time lost to repositioning operations.
