Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external measurement apparatus (GPS) and pre-input image information are used to land on dynamic targets, then landing precision is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent extracts and removes the external measurement apparatus (GPS) and pre-input image information requirements from the landing system. The aerial vehicle achieves precise landing on dynamic targets using only its own onboard imaging device and processing capabilities, eliminating the need for external aids and reducing system complexity.
Solution Approach 2:
The aerial vehicle serves itself by using its own onboard image device to capture, process, and track the dynamic target. The system performs self-navigation and self-landing through onboard image processing algorithms that calculate position, velocity, and landing parameters without external measurement devices or pre-input data.
2Measurement precision
If external measurement apparatus and pre-input image information are used, then landing precision is improved, but adaptability to changing targets and environments deteriorates
Solution Approach 1:
The patent implements a dynamic tracking system where the aerial vehicle continuously captures real-time images of the dynamic target and updates its position and velocity calculations throughout the flight. The image processing algorithms dynamically adjust to the target's motion, allowing the system to adapt to changing targets and environments while maintaining landing precision.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring the dynamic target's position through onboard imaging and adjusting the flight path in real-time. The image processing results provide continuous feedback on target location and motion, enabling the aerial vehicle to adapt its navigation and landing approach based on current conditions rather than relying on pre-input information.
3Measurement precision
If the aerial vehicle continuously tracks and adjusts flight parameters to maintain target centering, then landing precision is improved, but energy consumption increases
Solution Approach 1:
The patent applies partial action by implementing continuous image processing and tracking only during the critical landing phase rather than throughout the entire flight. The system captures images at specific intervals and processes them to calculate landing parameters, performing sufficient tracking to achieve precision landing while avoiding excessive energy consumption from continuous full-scale processing.

AI summary
The present invention relates to an aerial vehicle landing method, an aerial vehicle, and a computer readable storage medium. The present invention has no requirement on a motion form of a dynamic target and whether a measurement device is equipped, and does not require that a feature image of a target is obtained in advance either. Instead, motion information of a target is obtained by means of desirable tracking real-timeness of an on-board image device. Therefore, it is ensured that the aerial vehicle can reach a location near the target, and this process allows the dynamic target to have a complex motion form. Desirable tracking real-timeness allows an aerial vehicle to change a target at any flight time point, and continuous tracking and precise landing can be achieved.
