Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If geometric positioning algorithm is used to calculate position coordinates, then landing accuracy is improved, but computational complexity and processing burden increase
Solution Approach 1:
The patent uses a visual copy of the landing pattern displayed on the ground as a reference for the UAV to identify and land. Instead of complex geometric calculations, the system creates a visual replica (landing pattern) that the UAV can directly recognize and follow, significantly reducing computational requirements while maintaining landing accuracy
Solution Approach 2:
The patent replaces the mechanical/computational system of geometric positioning calculations with an optical/visual system. The UAV uses image recognition to identify the landing pattern visually, substituting complex mathematical computations with simpler visual detection and pattern matching processes
2Object-affected harmful factors
If landing pattern is dynamically changed, then interference avoidance is improved, but system complexity increases
Solution Approach 1:
The landing pattern is designed to be dynamically changeable, allowing the system to adapt to different environmental conditions and avoid interference. The pattern can be modified in real-time based on detected conditions, providing flexibility without requiring complex adaptive algorithms
Solution Approach 2:
The patent utilizes color changes in the landing pattern to convey different states and information to the UAV. By varying colors and visual characteristics, the system can indicate pattern changes, guidance information, and status updates, enabling interference avoidance through simple visual modifications rather than complex system changes

AI summary
The present disclosure provides a method, a device and a system for guiding an unmanned aerial vehicle to land. A navigation equipment on the unmanned aerial vehicle sends a landing instruction to the ground, so that a landing platform receiving the landing instruction displays a landing pattern. The navigation equipment scans image of the ground to identify the landing pattern, and guides the unmanned aerial vehicle to land at the landing pattern and land on the landing platform eventually. The landing platform displays a landing pattern according to the received instruction, and the unmanned aerial vehicle lands at the landing pattern, so that the unmanned aerial vehicle lands quickly and conveniently without extensive calculation.
