UAV Elevation Orbit Control for Vertical-Angle Inspection Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicles (UAVs) are limited to horizontal surrounding flight, restricting the capture viewing angle and reducing their functional practicability for applications like aerial photography and security inspection.
Innovation Solution
Implementing a method for elevation surrounding flight control that allows UAVs to fly along a vertical plane around a point of interest, using different flight rules for free and centripetal capture viewing angle modes, enabling the UAV to maintain specific flight attitudes and velocities for uniform speed and effective image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UAV performs horizontal surrounding flight only, then the flight control is simple, but the capture viewing angle is limited and functional practicability is reduced
Solution Approach 1:
The patent transitions the UAV flight from a two-dimensional horizontal plane to a three-dimensional vertical plane by introducing elevation changes. The UAV now flies around the point of interest in a vertical plane, enabling capture viewing angles from above, below, and side perspectives, thereby significantly expanding the adaptability and versatility of image capture while managing flight control complexity through structured flight rules.
2Adaptability or versatility
If the UAV adopts multiple flight rules for different capture modes, then the functional practicability is improved, but the control complexity increases
Solution Approach 1:
The patent implements dynamic flight control by defining different flight rules for different capture viewing angle modes. In free capture mode, the UAV maintains a perpendicular flight attitude to the trajectory. In centripetal capture mode, the UAV adjusts its attitude dynamically to always point the photographing apparatus toward the point of interest. This dynamic adaptation enables functional versatility while managing control complexity through mode-based rule switching.
Solution Approach 2:
The patent changes flight parameters (flight attitude, velocity adjustment) based on the selected capture mode. The system adjusts the UAV's orientation and velocity at different trajectory points to achieve uniform speed and proper positioning for image capture. This parameter adjustment strategy improves functional practicability for different inspection scenarios while keeping control logic manageable through parameter-based adaptation.
