UAV Landing Area Imaging for Safe Return and Attitude Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often cannot observe the landing area of a UAV when it is beyond visual range or obstructed, posing safety risks for the UAV and surrounding objects during landing.
Innovation Solution
Equipping the UAV with a photographing device that captures images of the landing area and sends them to a terminal device for display, allowing users to adjust the UAV's attitude to avoid obstacles and select a safe landing location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UAV operates beyond visual range or in obstructed areas, then the UAV can access more locations and expand operational capability, but the user cannot observe the landing area and safety cannot be ensured
Solution Approach 1:
The patent implements a feedback mechanism by capturing images of the landing area with a photographing device on the UAV and transmitting these images to a terminal device for display to the user. This allows the user to observe the landing environment in real-time or near-real-time, enabling informed decisions about landing safety while operating beyond visual range, thus resolving the contradiction between expanded operational capability and maintained safety
Solution Approach 2:
The patent introduces an intermediary system consisting of the photographing device, communication module, and terminal device display. This intermediary chain bridges the gap between the UAV's remote operation and the user's need for visual confirmation of the landing area, allowing safe operation beyond visual range by providing indirect visual feedback through captured images
2Extent of automation
If the user cannot observe the landing area, then the UAV can operate autonomously without user input, but the user cannot adjust the UAV position to select a suitable landing location
Solution Approach 1:
The patent creates a dynamic control system where the degree of autonomy can be adjusted based on user needs. The UAV can operate autonomously to navigate to the home point, but the user can switch to manual control mode by observing captured images on the terminal device and sending control instructions to adjust the UAV's position and select a suitable landing location, thus combining autonomous operation with user control flexibility
3Productivity
If the UAV lands without real-time environmental feedback, then the landing process is faster and simpler, but the safety of the UAV and surrounding objects cannot be ensured
Solution Approach 1:
The patent implements preliminary action by capturing images of the landing area before the UAV completes its landing approach. The photographing device acquires environmental information in advance, allowing the user to assess potential hazards and make necessary adjustments to the landing position or abort the landing if safety concerns are identified, thus preventing harmful outcomes while maintaining efficient landing operations

AI summary
An unmanned aerial vehicle (UAV) control method includes: obtaining a distance between the UAV and a home point; obtain, based on the distance, a first image captured by photographing a home point with a first photographing device; sending the first image to a terminal device for display; and upon receiving a first control instruction sent by the terminal device, adjusting an attitude of the UAV based on the first control instruction. The present disclosure can improve the safety of the UAV during returning and landing. A UAV, a system and a storage medium are also provided.
